Nothing Roland. I do exactly that but with a switch thats closed from its 
hit point clear to the chuck and beyond on my Sheldom lathe for Z 
homing. It's 10" or so from the chuck.  Cheap mini micro switches. $5 
for a bag of 10.  An error from either of the 2 stepper servos unhomes 
the machine as the reset on those requires a driver powerdown achieved 
with an f2 disable that shuts down a pair of 40 amp SSR's killing both 
sides of the 250 volt line. And I have .hal configured to do that. So 
after an error, I pull the tool holder, hit f2 to re-enable and rehome 
the machine which goes not destroy the previously set touch-offs. The 
rehome is within .0002" with those cheap switches, then re-install the 
tool and comtinue where it was interrupted. Whats not to like?

Take care and stay well.

I often feel like that I live in a world where cars have three wheels, and
no-one wants to believe that 4 wheels are better..

So  I don't understand why the reference strip in an encoder isn't half
black, half clear, along the full length. Now;
- there is only a single transition that marks the reference point
- it's always obvious which way to go to find that transition;  0:go left
   1:go right
- you don't have to worry (as much) about missing that obscure 'pulse'
- it will remove the homing dilemma plaguing machinists all over the world

What am I missing here?

I haven't tried this only because I have nothing running 
at the moment capable of doing this.
If the "reference channel" produces one pulse at a specific 
spot on the scale with no other pulses within a few tenths 
of an inch, you should be able to use it for precise 
homing.  You'd have a limit switch that would begin the 
search for index sequence of the homing routine.  Then, it 
would advance until it saw the pulse from the scale.  Just 
like the Z mark on a rotary encoder.

The code that works out this warning is often wrong, especially if you 
use offsets or probing. I find the warning more of a hindrance than a help.


However having soft limits is very useful and I don't like running 
machines without them. You know when you run code that if you get 
something wrong the machine won't hit it's hard limits. It's also nice 
when jogging to home. You can just hold the jog buttons until the 
machine stops. On smaller stepper machines you can also do away with 
hard limit switches. My plasma for instance just has home switches and 
rubber buffers as end stops. Once homed you can't hit the end stops 
unless something has gone very wrong (e.g lost steps).

[Emc-users] homing

[dave engvall]

Hi all;

For once I'm writing to say thanks to the developers for making the 
homing sequence quite flexible. .


As I get older I tend to use the KISS principle more and more. I'm 
chasing Gene down the path: just 3 years younger and still kicking.


Specifically, I use a cheap laser diode  and move manually  or jog to 
preposition the X and Y to a specific place. I mounted a tab on the 
right lower side of the table and adjust position so there is a small 
penumbra around a hole in the tab. Kick off homing and it finds the 
index and then proceeds to the predetermined offsets. Works a charm. 
For  Z I adjust manually to a given point and just kick it off.  It 
probably doesn't make much difference anyway since one always touches 
off to the top of the work. Just have to make certain I have enough 
distance between z max and work plane to back off. :-)

ps. the diode spot is about .125" so low power density.

The 'scratch' branch is dgarr/ihome_tst, commit 078206a11

Directory for wheezy-i386:
http://buildbot.linuxcnc.org/dists/wheezy/scratch-rtpreempt/binary-i386/

deb name:
linuxcnc-uspace_2.9.0~pre0~dgarr.ihome.tst~078206a_i386.deb

If users report that this fixes index homing problem on
the master branch, i'll merge the fix to the master
branch.

This bug requires some  effort to reproduce when lacking a
encoder with an index  --- but a tentative fix for index
homing on the master (2.9~pre*) branch is available as
a 'scratch' deb  from the buildbot for few days.

The 'scratch' branch is dgarr/ihome_tst, commit 078206a11

Directory for wheezy-i386:
http://buildbot.linuxcnc.org/dists/wheezy/scratch-rtpreempt/binary-i386/

deb name:
linuxcnc-uspace_2.9.0~pre0~dgarr.ihome.tst~078206a_i386.deb

If users report that this fixes index homing problem on
the master branch, i'll merge the fix to the master
branch.

Installed 2.8.0 and it worked correctly. Installed latest master and it 
faults. I have attached a linuxcnc_info.txt in case that helps. 
Unfortunately I can't find any buildbot builds more than a few days old. 
I'll see how long it takes to build linuxcnc on this machine...

If using the master branch, you should probably try 2.8
and report.

It is master as of a few days ago. The previous version which worked

and report.  The buildbot instructions at the
bottom of the page:  buildbot.linuxcnc.org
don't seem to show 2.8 but you can browse
http://buildbot.linuxcnc.org/dists/
to see if your OS and kernel (rtpreempt or rt(rtai)) have
debs available for 2.8.

For example, in the stretch directory, debs have names like:
linuxcnc-uspace_2.8.0~pre1.5067gf178a1739_amd64.deb

The hash following the 'g' is the commit (f178a1739)
The f178a1739 is the most recent commit for
the 2.8 branch (as of today 17aug19) as shown by
commit listing at:

If you find an appropriate deb, it can be
installed by commands:

$ wget the_deb ;# copy buildbot link
$ sudo dpkg -i the_deb ;# install the deb

From source I could just check out previous commits. The problem is 
that the router's computer is pretty slow and building LinuxCNC would 
take ages. Not good if I have to rebuild many times.

Is index enable connected to the PID component?

If these are both correct and you get this error, could you plot

when homing the first time?





I am seeing this on one of my axis, after upgrading from 2.5 to master.

It moves to the home switch, turns around to find the encoder index

pulse,

and after it finds the index, it faults with a following error - this

only

happens when I start Linuxcnc, ie when machine home isn't known.  If I

home

all again, it works fine.

This only happens on my regular axis, the other 2 are gantry pairs, which
don't fault.

I had FF1 set and command-deriv unconnected and it faults.  Setting all

FF

settings to 0 still faults.  If I connect the encoder velocity (from

5i20)

to command-deriv - it faults when I jog - the velocity coming out of the
pin
is very noisy.

Is this the same problem?

 If I leave it unconnected

Ahh thats a bug in index handling so I guess you will need to leave
the PIDs command-deriv unconnected until that is fixed.

I really really wish that index handling did not cause a joint position

jump.

this is just plain wrong and hatches a nest of ugly patch-arounds.

index)

is very noisy.



Encoder velocity should never connect to command-deriv, only feedback-deriv





Is this the same problem?



I dont think so, the change to PID only affects command-deriv and if you leave 
the command-deriv pin unconnected, the behaviour will be the same as before

I am seeing this on one of my axis, after upgrading from 2.5 to master.  

It moves to the home switch, turns around to find the encoder index pulse,
and after it finds the index, it faults with a following error - this only
happens when I start Linuxcnc, ie when machine home isn't known.  If I home
all again, it works fine.

This only happens on my regular axis, the other 2 are gantry pairs, which
don't fault.

I had FF1 set and command-deriv unconnected and it faults.  Setting all FF
settings to 0 still faults.  If I connect the encoder velocity (from 5i20)
to command-deriv - it faults when I jog - the velocity coming out of the pin
is very noisy.

Is this the same problem?

Thanks for that. I probably should have started this thread on the developer

Updating the master branch for improved

support both axis coordinate jogging (TELEOP_MODE) and joint jogging (not
TELEOP_MODE).

In general, changes for the master branch are described in the "Updating

Linuxcncrsh is specifically included at para 7.9 of:

The linuxcncrsh man page has also been updated to some degree for jogging

Re: [Emc-users] Homing XYAY configuration

[Dewey Garrett]

(oops -- posted to wrong thread earlier)

linuxcncrsh (actually src/emc/usr_intf/emcrsh.cc)
has been updated to a *limited* extent for the
master branch with joints-axes updates.

The extent of updates has primarily been to
maintain the scripts that are used in the runtests
suite of tests.  These scripts are run on the
buildbot (for all supported operating systems) at
each new commit.

In src/emc/usr_intf/emcrsh.cc:setHome(), the code
for "Home All" (== -1) is rejected in both the
master branch AND 2.7.  The absence of this
particular functionality is likely indicative of
the limited usage of linuxcncrsh in the wild.

I've pushed a commit to add this "Home All"
capability and verified the runtests are still ok
on my test machine.

The commit, for the master branch only, is:
https://github.com/LinuxCNC/linuxcnc/commit/b3568fb9094b0075087242fc543c8db0d8e3ad40

#--
There may be other features available in guis
that are not implemented in linuxcncrsh.  If you
make changes and push them to the master branch of
git, it will be important to run the runtests
suite to ensure that the expected output of
existing test scripts is not altered since
alterations may cause test (and buildbot)
failures.

[Emc-users] Homing XYAY configuration

[Eric H. Johnson]

All,

I am running Lcnc 2.8.0-pre1 in an XYAY configuration. I use the linuxcncrsh 
interface for my user interface. It is looking like there are additional 
commands that need to be supported.

Home all, for example, on axis runs differently than doing the same thing over 
linuxcncrsh. Also, I cannot jog over linuxcncrsh, but can with axis. MDI 
commands, and presumably gcode files do work over both interfaces.

It so happens I wrote linuxcncrsh. Are there additional commands that need to 
be supported?

Thanks,
Eric

Thanks,
Eric

Subject: [Emc-users] Homing To Index Following Error

I gave Master a try using only 4 joints for my XYZW machine, and that did not 
make any difference.
I still get a following error on the W (joint3) every first try. (unless the W 
is parked against the limit switch at machine turn on.)

I don't understand why it always seems to work right for the Z axis, but never 
for the W. When I scope the homing of the Z the plots look the same, except for 
the obvious spike of following error on the W, and the time between when the 
index-enable changes and the step in the position feedback. The Z shows they 
happen together in halscope, and W seems to be separated by a couple of 
base-thread cycles.

Is that the source of the problem? And what if anything can I do about it?

--


Pretty sure the mix  of base thread and servo thread cycles is what causes
the problem, homimg to index requires a precise function ordering and I 
dont think you can have the correct function ordering when you have the base 
thread accesing hardware.


I suspect the easiset solution is to choose a fast enought host CPU  that 
is capable of running a 4 KHz or so servo thread

Is W a second spindle axis?

I wonder if you are the only one actually homing a W-axis?

I recently had Z axis homing problems on my HNC lathe. I watched the 
encoder signals with HALscope while turning the screw forward and back 
by hand. I lost position over a few cycles. It turned out to be a bad 
capacitor that was causing the encoder voltage regulator to randomly 
shutdown. I removed the capacitor and function was restored. So, your 
problem may be like this, where the fault may not be consistent or obvious.

If the latch move is slow enough (so the index signal is capturable by 
halscope with a servo thread update rate), capturing a halscope trace of index 
and index-enable might help diagnosis

setp-ing the index-enable pin will not work, but sets-ing the signal that 
carries the index-enable does work and does not require disconnecting hal pins

The 7I77 cannot "store" any encoder counts as it only has encoder input signal 
conditioning on card, though cycling the 7I77 power when LinuxCNC is running 
will like cause a few stray counts. Note the raw counts are not cleared at 
linuxcnc start so can be any initial value (encoder counts and position _are_ 
cleared at linuxcnc startup and encoder position is cleared by index if index 
enable is true). Is it possible that something on the drive changes with 7I77 
power cycles.

How does the Resolver to Quadrature converter decide where the index
is? It might do it on a fixed part of the cycle (the LinuxCNC 7o49
driver does) or it might just pulse every 8192 counts.

The latter method won't work well.

Is the error exactly one turn, or is it truly random?

[Emc-users] Homing to index ends at different positions

[Marius Alksnys]

LinuxCNC 2.7.7, hostmot2, Mesa 5i25 + 7i77, resolver to quadrature 
converter integrated into servo drive, 8192 counts per revolution.

I finished integration and one day operator said that Z position was 
lost after last machine restart.

I checked Z homing process and got different final Z positions at 
different tries, especially after PC and 7i77 5V re-powering.

Then I observed that looking for an index sometimes does not actually 
stop at the index, but at the next one - after one full turn. Would it 
be noise or inverted signal problem it would interpret noises as index 
pulse and would stop faster, not further, but this does not happen.

I played a lot with HOME_LATCH_VEL, making it much smaller, changing its 
direction, but could not get reliable results. I checked position of 
home switch in relation to index position and moved the flag of home 
switch, got around 1200 counts difference between them, but nothing helped.

And now, as I can recall, homing to index with Mesa boards gave me 
problems here and there often. Final workaround was to disable this 
feature and rely on imprecise home switches only :(

[Emc-users] Homing a lathe like the little monster

[Gene Heskett]

Greetings all;

The little monsters ways have been tightend up and it should carve to 
about a thou tolerance for a few days anyway.

Currently using homing switches, with figures in the ini file that while 
not accurate, are at least consistent, which I need to redo the Z axis 
for the size of the new tapered clamps. And I'll likely restore that yet 
today.

But I need something I can tie into a G38.2 in order to do a fine tune of 
the base G54 co-ordinate map to establish a true zero diamater at 
x=0.000.

I am thinking of some sort of an insulated holder I can clamp in the 
chuck, with a bit of give so that I can start the spindle in reverse and 
even though it may be a few thou off-center, a cutting tip would just 
slide along, and if I can access the time open and closed, drive it to a 
50% duty cycle, then add the probe radius to the x value and apply to 
the G54 co-ords such that 0.000 is x dead center.

For repeatability I should so something similar for the z but the shape 
of the tool tip would tend to muck that up unless I only drive x to 
about -.001" for that measurement.

So is there someplace in the linuxcnc memory where I can access the 
elapsed open or closed times of such a cyclic contact?  And make those 
times available to gcode for the math needed?

Cheers, Gene Heskett

Re: [Emc-users] Homing

[Neil]

Okay, found it.  Apparently when I set the sequence in the ini file, the 
Home Axis button changes to Home All automatically.

Thanks.

 Yes you can, and you can change the order of the homing by axis.

 It's in the system integrator manual.   Search for homing.

Another thing I had not yet come across... that the Home button and

 Do you have, in your .ini file, a line per axis stating

 HOME_SEQUENCE = number?

 The number, starting with 0 determines the order that the axises are
 homed in.

 If its missing, I don't think axis gives you anything but the dots to
 select the axis to be homed when the HOME button is clicked on, or the
 keyboard HOME key is pressed.

 When the HOME ALL has been configured correctly, then the keyboard
 shortcut of Ctrl+HOME keys will do it all.  My Z home is fairly close to
 the chuck on my lathe, so I am in the habit of emptying the toolpost
 else it can break expen$ive tooling if there is work in the chuck.
 BTDT. :(

 Because of the preparation to make sure the machine CAN move w/o damaging
 anything, I have serious doubts that LinuxCNC will ever have a 1 time,
 at launch time, automatic home.  That could/would be quite dangerous in
 everyones opinion. IOW the lack of it is a safety feature.

 Cheers, Gene Heskett

Thanks for your report.

In master branch, I have made some changes regarding parallel port
registration in order to support uspace realtime.  I will test later
today whether my work caused this problem.  If so, I'll fix it.

Please remember that the master branch is for new and potentially
untested work, so instability like this occurs much more frequently than
in our stable release branches such as 2.6.x.

Re: [Emc-users] Homing and restarting Lcnc problem

[Jeff Epler]

I tested for the hal_parport device or resource busy problem but was
unable to reproduce it.

I tested on a debian 7 system recently installed from the hybrid.iso.  I
tested at a master branch revision which describes as
v2.6.3-659-gce43af0 (today's master branch) using a standalone test
script in the file pp.hal

loadrt hal_parport cfg=0
loadrt threads period1=100
loadrt not 
net x not.0.out = not.0.in parport.0.pin-01-out
addf not.0 thread1
addf parport.0.write thread1
start

which I ran multiple times in succession with

halrun pp.hal

I did not receive any errors in the terminal or in dmesg.

On my system, the install parport_pc /bin/true line is commented out
in /etc/modprobe.d/linuxcnc.conf, so hal_parport is working in
cooperatin with the linux parallel port driver.  My parallel port is on
a PCI card.

If you can, please test with the standalone hal script (modifying cfg=
if necessary) to see whether that produces the problem for you.  But the
most basic explanation (that I completely botched the unregistration
process for rtai when adding uspace) seems to be discounted at this
point.

If the std linux parport driver is available, and udev loads it, the 
results are similar.  So if you have that driver in the 
/lib/modules/kernel-version tree, nuke it.  In the meantime, rmmod it if 
it shows up in an lsmod listing before you start linuxcnc.

This is a rather elderly problem if that is the problem, but it can still 
bite a new bee.

 results are similar.

No, that has not been true for a long time now.

Since version 2.4.0 (2010), linuxcnc has by default cooperated with the
Linux parallel port drivers, so hal_parport and other parport-using
drivers generally do not interfere with or experience interference from
the kernel parport_pc driver.

For that reason, systems installed since that time have the modprobe.d
line that would disable parport_pc commented out by default.

One great advantage of this, which we have probably not evangelized hard
enough (or scrubbed away all documentation to the contrary), is the
ability to refer to parports by their linux numbering, not worrying
about I/O port addresses:
loadrt hal_parport cfg=0
points at the system's default parallel port, if linux detected one.
Super easy, and it even worked on my system where the only parport is a
PCI-E one!

Some people may still feel more comfortable with parport_pc not loaded.
This reduces the risk that some linux software (such as the printing
system) will touch the port, causing the attached CNC to do something
unexpected.  Those people can uncomment the line or take more drastic
measures if they prefer.  (best possible measure to take: a proper
physical estop chain so this doesn't happen even when somebody boots
windows 98 from cdrom or whatever crazy thing you might imagine)

 why all switches working good on emc2 --- 2.2.4/2.2.5 and do not work
 on emc2--2.5
 ?
 why nobody answer that question?
 do not need to see my machine. obvious problem with 2.5
 ///
 If one do not see the problem with 2.5, than my clear question is who
 else use 5i20 /7i33/7i37  with emc2---2.5?

And I believe this is the first time you have said you are using Mesa's 
interface boards. But then again, my short term memory isn't the greatest, 
one of the hazards of outliving ones enemies. :(

 just want to know answer
 my question is simple and clear.
 
 Here is most important point and please!!! Attention here!
 when i use emc2 -- - 2.2.4/2.2.5
 all LED lights on board 5i20 are ON

I do not know about the 5i20, but the docs on my 5i25 tells me that if 
both leds are on, the board is miss-configured and incapable of working. 
So the first thing I would do is go to Peters site and download  print 
the 5i20's documentation.  That is at:

http://mesanet.com/pdf/parallelcardinfo.html

However, according to the 5i20.pdf, all leds on, on the 5i20 indicates all 
outputs are at logic zero.  As that is the default power up state, I do 
not think it has been configured.

Can you move the machine with the arrow keys after the F1, F2 enable 
sequence?

I do not see the 7i33, but the 7i37 docs are on that same page if you 
scroll down.  Backing up to mesanet.com, and clicking on Anything Daughter 
cards will get you to where the 7i33 docs are.  Get those also.

Next, trace or ring the switches, they are connected to what terminals, 
I assume on the 7i37, since the 7i33 is apparently all servo  encoder 
interfaces.  Tell us that info too.  Properly setting up this 3 board  
combination is far more complex that the standalone 5i25 I am attempting 
to use.

Do you have a backup of the old install of 2.2.4?  It could be used for 
comparison with the 2.5.4 install.

Re: [Emc-users] Homing?

[a k]

i will check , but about all - every single LED was ON on 5i20 or no I can
not say but when i used -emc2--2.2.4 there was many LED light ON
some on middle of the board and some on the side of the 5i20 board.
when i use emc2---2.5.4  NONE of LED was ON..

How that very big and obvious difference can be explained?
And i want to attache to it that limit and home switches stop work on
emc2---2.5.4 
Is this simple coincidence?
That is why i want to find out who else use emc2---2.5.4 with boards
5i20/7i33/7i37?

if one can replay that yes i have used exact same combination ---
emc2---2.5.4 with boards
5i20/7i33/7i3 and no problems--- limit switched working than it sound
complicated .
//
I am not a developer who buckle down emc2-- 2.5.4

  all LED lights on board 5i20 are ON

 I do not know about the 5i20, but the docs on my 5i25 tells me that if
 both leds are on, the board is miss-configured and incapable of working.
 So the first thing I would do is go to Peters site and download  print
 the 5i20's documentation.  That is at:

 http://mesanet.com/pdf/parallelcardinfo.html

 However, according to the 5i20.pdf, all leds on, on the 5i20 indicates all
 outputs are at logic zero.  As that is the default power up state, I do
 not think it has been configured.

 Can you move the machine with the arrow keys after the F1, F2 enable
 sequence?

 I do not see the 7i33, but the 7i37 docs are on that same page if you
 scroll down.  Backing up to mesanet.com, and clicking on Anything Daughter
 cards will get you to where the 7i33 docs are.  Get those also.

 Next, trace or ring the switches, they are connected to what terminals,
 I assume on the 7i37, since the 7i33 is apparently all servo  encoder
 interfaces.  Tell us that info too.  Properly setting up this 3 board
 combination is far more complex that the standalone 5i25 I am attempting
 to use.

 Do you have a backup of the old install of 2.2.4?  It could be used for
 comparison with the 2.5.4 install.

One more question.  Have you executed pncconf?  If not, then the whole 
install is un-configured. Setting up a new install while using that 3 
board combination IS a complex process that requires intimate knowledge of 
how the system was setup in order that it be duplicated using more modern 
syntax.  So, whoever did it for you in the first place, or someone with 
similar skills will have to come to your site and do it again. I am not 
that person, and never having used that board combination myself, I can't 
do any more than ask the std troubleshooting questions.  I asked you to 
show us an ls -lR of the linuxcnc/configs directory tree and you have 
not even done that.  That was so that we might be able to guess which file 
we wanted to see. So there was a reason to ask you to do that, but you 
have refused.  Without some clues, we are as lost as you are.

You were asked to send your 
~/aram/linuxcnc/configs/machine_name/machine_name.hal file, where 
machine_name? is what you see in the top border of the axis display as 
something similar to axis.ngc - AXIS 2.5.4-30-g80efa5f on my-mill-atom-3
In my case then we would want to see, from that
~/home/aram/linuxcnc/config/my-mill-atom-3/my-mill-atom-3.hal.

And I would like to see that same file (machine_name adjusted of course) 
from the original 2.2.4 install, the one that worked.

That machine_name is totally unknown to us, so there is no way we can tell 
you what file it is.

Its obvious to us all by now that it was NOT YOU that set it up and made 
it run nearly a decade ago, and that you are going to have to get that 
person to come back and do it again.  And the nature of free software is 
that while it is free, the labor of knowledgeable people who can make it 
work is not.

What I believe has happened is that you were originally using the old m5i20 
firmware and your own hal file, When you changed to 2.5.4 you started using 
the hm2-servo _Example_ hal file. The example hal file hs no limit switch 
support built in so you will have to add the limit switch connections in the 
hal file in order for them to become functional

  --One other question:  Did you make a new config directory, with new

  i did explain that..
  i did load 2.5.4
  and switches do not work!
  I did use 2.2.4 as a live CD without installation and all switches do
  work . any more question about configuration?
 
  Then that would have been two different sets of configuration
 directories,
  the live cd would have been volatile, in ram, the install of 2.5.4
 would
  be as named subdirectories of ~/you/linuxcnc/configs.  Show us an ls
 -lR
  of this configs directory please.
 
  ,,,
  about --English is not your first language---
  i do not see difference between 1 st or 2nd one
  what i can not see it is clear instruction/direction:
  step 1 - 2...  n
 
  I gave you start points in the last post. You refuse to take even the
  first step required to troubleshoot.
 
  Also, I can assure you that it is not LinuxCNC as I have 2 installs
 here
  that do work.  It is a configuration error.
 
  what is result? etc ,
  what to check in  Hal Meter? which file?
  where -- pins- signals--parameters-- ?
  i will do that but i need clear direction to i can be clear about
  result/outcome.
 
  
 
  I did many times ask question but i can not see the answer.
  why all switches working good on emc2 --- 2.2.4/2.2.5 and do not work
  on emc2--2.5
  ?
  why nobody answer that question?
  do not need to see my machine. obvious problem with 2.5
  ///
  If one do not see the problem with 2.5, than my clear question is who
  else use 5i20 /7i33/7i37  with emc2---2.5?
 
  And I believe this is the first time you have said you are using Mesa's
  interface boards. But then again, my short term memory isn't the
 greatest,
  one of the hazards of outliving ones enemies. :(
 
  just want to know answer
  my question is simple and clear.
  
  Here is most important point and please!!! Attention here!
  when i use emc2 -- - 2.2.4/2.2.5
  all LED lights on board 5i20 are ON
 
  I do not know about the 5i20, but the docs on my 5i25 tells me that if
  both leds are on, the board is miss-configured and incapable of
 working.
  So the first thing I would do is go to Peters site and download  print
  the 5i20's documentation.  That is at:

Approximately right but you are not using a parallel port
so the pin names of the hardware side will be different something more like:

net Xhome  axis.0.home-sw-in = hm2_[HOSTMOT2](BOARD).0.gpio.048.in_not


Note that the gpio number (the 048) depends on which 5I20 connector the
7I37 is connected to and which 7I37 input the limit switch connects to.

(the 048 is just an example)

will it be automatically 2.5.4   ? or 2.5  etc?

 I suspect you are not showing an exact copy, that switch, if you have them
 wired separately, should have a label home switch x or y or z.

 It is very important that you copy us exactly what you see on screen,
 including the menu paths.

  //
  in
  hal_meterParameterhm2_5i20.io_ error
 was the space between io_ and error there?

 Now, I am in the middle of making a 5i25 move my small lathe so I am at
 the limit of what I can do here.

 But I note that when linuxcnc is shut down, every tally led on my C1G BOB
 goes to full brightness.  If the spindle worked, it would be turning the
 motor wide open, somewhere in the 15,000 revs range at the motor shaft.
 My steppers are moving, but very slowly, max 99mm a minute, and with VERY
 leisurely accelerate/decelerate.  This was first light so to speak.  The
 step pulses are so narrow I have to put me in the dark to see a very faint
 glow from the tally leds.  And both stepgens are running the motors
 reverse of the correct direction.  But I have not turned on my Hitachi
 100mhz dual trace scope to see whats going on yet.  Some of these fixes
 will be fairly simple I believe.

 But its about 90F in the shop, I'm 79 and quite well done in this heat so
 for me it can wait.

  i can not read that but it error

 Did you use synaptic to install it, using this line (just add it to the
 bottom of the list) in your /etc/sources.list:

 deb http://buildbot.linuxcnc.org lucid v2.5_branch-rt

 If its not in that list, you will not get automatic updates.

 Both update-manager and synaptic share this list.  You have to
 sudo gedit /etc/apt/sources.list to add that line, and then
 sudo update-manager to update to the last build
 or
 sudo synaptic to un-install/re-install

 hi
 i think that problem in my download
 i will make another CD
 when i download from
 New Installation

1. Download the ISO
http://www.linuxcnc.org/iso/ubuntu-10.04-linuxcnc3-i386.iso

 will it be automatically 2.5.4   ? or 2.5  etc?

 thank you

  Hi
  in hal_meter  a lot thing, i need to know which one to check.

  hal-metersignalshome switch False
 
  only x axis home switch change it to True.

 I suspect you are not showing an exact copy, that switch, if you have them
 wired separately, should have a label home switch x or y or z.

 It is very important that you copy us exactly what you see on screen,
 including the menu paths.

  //
  in
  hal_meterParameterhm2_5i20.io_ error
 was the space between io_ and error there?

 Now, I am in the middle of making a 5i25 move my small lathe so I am at
 the limit of what I can do here.

 But I note that when linuxcnc is shut down, every tally led on my C1G BOB
 goes to full brightness.  If the spindle worked, it would be turning the
 motor wide open, somewhere in the 15,000 revs range at the motor shaft.
 My steppers are moving, but very slowly, max 99mm a minute, and with VERY
 leisurely accelerate/decelerate.  This was first light so to speak.  The
 step pulses are so narrow I have to put me in the dark to see a very faint
 glow from the tally leds.  And both stepgens are running the motors
 reverse of the correct direction.  But I have not turned on my Hitachi
 100mhz dual trace scope to see whats going on yet.  Some of these fixes
 will be fairly simple I believe.

 But its about 90F in the shop, I'm 79 and quite well done in this heat so
 for me it can wait.

  i can not read that but it error
  //
  i think that this down load CD is bad and i can not fix it.
  i need get good down load where all witch work like it was with emc2
  --2.2.4.

   I'm running the latest 2.5.4 i think my is 2.5

 Did you use synaptic to install it, using this line (just add it to the
 bottom of the list) in your /etc/sources.list:

 deb http://buildbot.linuxcnc.org lucid v2.5_branch-rt

 If its not in that list, you will not get automatic updates.

 Both update-manager and synaptic share this list.  You have to
 sudo gedit /etc/apt/sources.list to add that line, and then
 sudo update-manager to update to the last build
 or
 sudo synaptic to un-install/re-install

   Do NOT leave out any details.
  
   Tell us every button push and what happens after every button push.
   Tell us everything you see and do. It is almost impossible to send

   Then when someone answers you and/or asks you a question you MUST

   Don't leave out ANY details as this problem is caused by a minor

 hi
 Gene

That will be highly dependent on your hal file, specifically on how many 
modules you have loaded, and how many functions/pins they each have.

So I can't begin to predict what you will see in the menu's.

Each module will have a name, and each will have functions and pins driven 
by signals, or driving signals as the logic is hooked up by hal, the 
Hardware Abstraction Layer.  A question on a specific module and its 
named pins can often be deduced from a man 9 module_name.

A signal is usually named as the next option to the right of a net 
statement.  Which means it could be named anything you want.  The third 
argument in a net line of the hal file is the source module.#.pin#, 
UNLESS that signal name has been used before, in which case the third and 
succeeding arguments are all places where this signal is to be delivered.
That way you can feed a given signal to more places than you can nicely 
type on one line.

There is more of course, but this needs to be digested, so you can build 
on that.

Ok, while its running but idle, look at the parport pin your home switch 
is coming in on.  Move the machine to where you know the switch is 
activated, see if hal_meter shows the change in status, then consult a 
printout of your hal file to see what net name is associated with that 
parport pin. Trace that signal_name to see where all it goes, and use 
the hal_meter to verify it is getting there.  At some point, it should hit 
the motion module as a home signal, so check it there while moving the 
machine on and off the switch.

What my mind keeps coming back to is that  your .hal file was built in 
2.2.4 days, and may be using old syntax.  The old syntax is supposed to 
work yet, but perhaps there is now a place where it falls thru the 
crack, aka a bug. 2.2.4 is very, very long in the tooth now. It may be 
that you've found a bug.  Serious errors of course and it will not start, 
but it will tell you in the window you tried to launch it from, what was 
wrong.

The dmesg command in that window might have a clue, so look the last 50 or 
more lines of that over carefully.

how to identify and find that problem?

You are either not familiar with the machine, not having done the original 
install, or are not doing as I suggested.  So we wonder if your hands even 
fit the tools.

We, none of us, are mind readers, so you must be willing to either act as 
our hands by remote control by following the directions we give, or if one 
of us is close enough, possibly pay for a visit to your place so we can 
use our own hands.  That means we have to know where you are on this wet 
ball of iron  rock called earth.

There are enough refinements in 2.5.4 that the upgrade once done, will 
surprise you at just how much better it runs.

There may also be a language comprehension factor here since I suspect 
that English is not your first language.  If that is the case, what is 
your native language?

Perhaps someone else here may be able to help you in your own language?

One other question:  Did you make a new config directory, with new files 
when you installed 2.5.4?  Or are you still using the configuration from 
2.2.4?

i did explain that..
i did load 2.5.4
and switches do not work!
I did use 2.2.4 as a live CD without installation and all switches do work .
any more question about configuration?

,,,
about --English is not your first language---
i do not see difference between 1 st or 2nd one
what i can not see it is clear instruction/direction:
step 1 - 2...  n
what is result? etc ,
what to check in  Hal Meter? which file?
where -- pins- signals--parameters-- ?
i will do that but i need clear direction to i can be clear about
result/outcome.



I did many times ask question but i can not see the answer.
why all switches working good on emc2 --- 2.2.4/2.2.5 and do not work on
emc2--2.5
?
why nobody answer that question?
do not need to see my machine. obvious problem with 2.5
///
If one do not see the problem with 2.5, than my clear question is who else
use 5i20 /7i33/7i37  with emc2---2.5?
just want to know answer
my question is simple and clear.

Here is most important point and please!!! Attention here!
when i use emc2 -- - 2.2.4/2.2.5
all LED lights on board 5i20 are ON

and
when
i use emc2---2.5
NONE of the LED light on 5i20 are ON 

does that show clear that problem in 2.5!
to be clear:  problem in emc2---2.5 for 5i20

and not in my machine?
?
i want to ask again --who else use 5i20 /7i33/7i37 with emc2-2.5?

   What my mind keeps coming back to is that  your .hal file was built
   in 2.2.4 days, and may be using old syntax.  The old syntax is
   supposed to work yet, but perhaps there is now a place where it
   falls thru the crack, aka a bug. 2.2.4 is very, very long in the
   tooth now. It may be that you've found a bug.  Serious errors of
   course and it will not start, but it will tell you in the window you
   tried to launch it from, what was wrong.
  
   The dmesg command in that window might have a clue, so look the last
   50 or more lines of that over carefully.
  
what file need to check to see problem?
i can turn camera and you can see monitor in real time.

[Emc-users] Homing?

[a k]

Hi
i did try to home machine and i found that all my limit and home switches
stop working.
everything was good when i used emc2 --2.2.4
now i have emc2 ---2.5
i put back emc2  2.2.4 and start it like live CD - without loading and all
my limit switches working again good.

looks like all limit switches stop working because problem with emc2
--2.5--
am i first that found this problem?
maybe problem when i download --2.5--?

thanks

This sounds odd Aram.  I'm running the latest 2.5.4 on my lathe, with all 
the home switches common on one pin, and they are working fine.

The syntax in the .hal file has changed, and I am using the new keywords, 
but I don't believe the old ones have been made invalid.  Yet.

Do you get any errors reported on the shell window you start linuxcnc -l 
on?  They are usually pretty specific, showing the bad line in the file 
when they are reported.

You can also use the hal_meter, under the machine tab, to follow the 
switches as they come in.  With a printed copy of the .hal file in hand so 
you can see where they are hooked up, you can use the meter to see where 
they might be getting lost.

Cheers, Gene Heskett

Aram,
  The description working good and then not working is not very
informative. You need to describe what happens as clear and complete as you
possibly can.

Do NOT leave out any details.

Tell us every button push and what happens after every button push. Tell us
everything you see and do. It is almost impossible to send too much
information when you request help.

Then when someone answers you and/or asks you a question you MUST answer
their questions and respond to their suggestions and thoughts.

Don't leave out ANY details as this problem is caused by a minor detail
that is probably something you have done (or maybe not done).

When someone responds to your request for help you need to then become a
helper to the person responding to your request.

Pay close attention to what they say or suggest. Do what they want you to
do and then respond with answers that only relate to the questions or
suggestions they sent.

thanks
Stuart

I suspect you are not showing an exact copy, that switch, if you have them 
wired separately, should have a label home switch x or y or z.

It is very important that you copy us exactly what you see on screen,

was the space between io_ and error there?

Now, I am in the middle of making a 5i25 move my small lathe so I am at 
the limit of what I can do here.

But I note that when linuxcnc is shut down, every tally led on my C1G BOB 
goes to full brightness.  If the spindle worked, it would be turning the 
motor wide open, somewhere in the 15,000 revs range at the motor shaft.  
My steppers are moving, but very slowly, max 99mm a minute, and with VERY 
leisurely accelerate/decelerate.  This was first light so to speak.  The 
step pulses are so narrow I have to put me in the dark to see a very faint 
glow from the tally leds.  And both stepgens are running the motors 
reverse of the correct direction.  But I have not turned on my Hitachi 
100mhz dual trace scope to see whats going on yet.  Some of these fixes 
will be fairly simple I believe.

But its about 90F in the shop, I'm 79 and quite well done in this heat so 
for me it can wait.

Did you use synaptic to install it, using this line (just add it to the 
bottom of the list) in your /etc/sources.list:

deb http://buildbot.linuxcnc.org lucid v2.5_branch-rt

If its not in that list, you will not get automatic updates.

Both update-manager and synaptic share this list.  You have to 
sudo gedit /etc/apt/sources.list to add that line, and then 
sudo update-manager to update to the last build
or
sudo synaptic to un-install/re-install

Re: [Emc-users] Homing with index and bldc in qi mode - a bug?

[Marius Alksnys]

It is index enable signal. But bldc.init stops its init sequence after 
axis.n.index-enable turns this signal low and it does this every single 
period!

And I can think of more cases where index-enable could be used, but it 
would not be possible when it is connected to axis.n.index-enable.

That _should_ be OK.

Every servo cycle the motion controller first reads the inputs:
control.c: 512 joint-index_enable = *(joint_data-index_enable);

Then after processing, writes the new values:
control.c: 1873 *(joint_data-index_enable) = joint-index_enable;

Unless the homing code has set the joint-index_enable then the value
of the pin should be unchanged.
homing.c: 652 joint-index_enable = 1;

It does seem odd that the pin is read then written with no apparent
forcing of the sequence. Motion really ought to only write to the pin
if it has decided it needs to change the value.

It might be that your problem is caused by the bldc and motmod
components executing in an unfortunate order.

What do you mean by cycle, sequence and comp?

As I wrote earlier - when axis.n.index-enable is disconnected, and 
bldc.init takes place, motor start to spin, index-enable goes high, 
motor encoder reaches the index and then it goes low like it should be.

But when axis.n.index-enable is connected, the motor even does not start 
to rotate and index-enable signal goes low immediately!

[Emc-users] Homing with index and bldc in qi mode - a bug?

[Marius Alksnys]

BLDC init works nicely, but only if axis.0.index-enable is not connected 
to index-enable signal. Otherwise BLDC init stops just started.

I checked the code and found that axis.n.index-enable IO pin is set at 
every servo(?) period no matter it should be changed or not. That's why 
bldc.init can't complete normally.

I think I could fix this in sources and test, but maybe someone could 
fix and release the fix to master?

I am using Hostmot2 and Mesa 7i85.

That's interesting. I can't see why that would be, as it would tend to
mean that an encoder could never work for axis position...

Can you show me the relevant bit of HAL?

[Emc-users] Homing with index solution on BLDC at qi mode

[propcoder]

Does someone made such a solution?

On my setup BLDC init runs right only after several times. It ends with 
joint following error most often. And sometimes it looks ok, but by 
running a motor I realize that bldc.encoder-offset is not set correctly.

As wiring all needed components for homing is a bit tricky, I thought 
maybe someone will share already made hal and ini config files.

And for perfection, it would be nice to have universal config for init 
and homing procedure doesn't matter where the axis is located initially 
- at one or another end or at the middle.

The way to avoid the following error problem is to home the motor
before enabling motion.

net init1 iocontrol.0.user-enable-out bldc.0.init
net init2 bldc.0.init-done iocontrol.0.emc-enable-in

Would work for a single axis. For muliple axes you would need to and
the init-done pins together, which is probably more convenient with
logic than with and2

[Emc-users] Homing?

[Gene Heskett]

Greetings all;

I just trim to trim the z backlash (its hopeless, wait for new ball screw) 
and set my auto-zero-cal code up to establish its home position as being 
the back end of this gage I have made.

The code I think, is doing exactly what I wrote it to do, but when I run 
it, expecting it to set the co-ordinates of g54 properly, I find its 
setting it relative to whatever it thinks home is.  Not at all useful.

It appears that I need a method to use this gage twice, once to home the 
lathe, and then to establish the offset, the touch off IOW, doing both 
again when I have completed a part and have brought the stock thru the 
chuck and re-clamped it in preparation for making the next copy of the 
part.

So it appears I will need to do an ini axis homing section, per axis to 
home it, but this is going to need a switchable home method dependent on 
the tool mounted since the x home will need to be searched from the outside 
in for a normal tool, but from the inside out for a boring bar tool.

So, is there a way to use the tool number to switch this homing sequence?

Or, alternatively, and AFAIAC, the much better way, a method of setting the 
home position of an axis from gcode?  Something like a brute force 
setting of one of the $5xxx variables?  Home as one of those vars, doesn't 
seem to be assigned in the rather limited list included in the G54-etc 
section of the gcode.  All that covers is the variations of co-ordinate 
systems.

Then, can I 'net' the debounced signal from the probe, into the motion.home 
tree somehow, but without normal probe activity mucking with motions idea 
of 'home'?

Thanks for any guidance.

Cheers, Gene

 I have set the homing sequence that Z homes first and then all the
 remaining joints.

If they share a home, they need to home in strict sequence one at a time.
However, reading more carefully, it sounds like you are homing Z to a
shared limit, but the other axes have home switches.

 What else am I missing here?

Possibly HOME_IS_SHARED ?
http://www.linuxcnc.org/docview/html/config_ini_homing.html


 After a long search I  found this one in manual:
 To use only one input for all homing and limits you will have to
 block the limits of the axis not homing with axis that is homing in
 HAL.

 I think that it could be done this way:
 loadrt mux2
 axis.2.homing = mux2.sel

mux2 doesn't work with boolean data, unfortunately.

 Is there any other simple and easy way to do it?

Guessing that you are looking at the inverted pins, so that 1 =
tripped, then you want limits AND NOT z-homing.
loadrt and2
loadrt not

net home-not axis.2.homing = not.0.in
net limit-mask and2.0.in0 = not.0.out
net all-limits-in and2.0.in1
net all-limits-out and2.0.out

 I have another problem:

 Z should home on its upper position and stay there.
 So in INI file I set:
 HOME =                  180.000
 HOME_OFFSET =           180.00

 It homes, sets joint coordinates to 180 and goes to 0 ignoring HOME = 180.

It's been a while, but I think HOME_OFFSET is the distance from the
switch point to the home position, so if the home switch is at 180 and
the home position is 180 then HOME_OFFSET is zero.

For what i know OFFSET should be the same of HOME, if you want the joint

so:
HOME = 180.0
HOME_OFFSET = 180.0

I do not know, what is boolean, but You are right - it did not want to
work, because limit/homing switches are bit pins, mux2 inputs and
output are float.

So I created mux2bit component, where I fixed this...

So that part is working.

Yes, I know that it _should_
But it does not!

Andy, it is working correctly up to the point, where it trips the
switch and sets the joint position as stated by home_offset.

The mysterious part is:
Why on earth it has to move to 0, when HOME is  set to be equal with
HOME_OFFSET, sho it should just stay there...

Re: [Emc-users] Homing

[Frank Tkalcevic]

In AXIS_1 and AXIS_2 section, you have HOME defined twice.  Once at 0, the
other at 10.0.
