Re: [Emc-users] Can't get XHC-HB04 MPG to work

[dannym]

Didn't realize I sent off-list.

OK, I think I see a key problem, under Hal Meter, "xhb-hb04.require_pendant = 
false", although "connected" is true.

Right in the main .ini:

[XHC_HB04_CONFIG]
require_pendant = yes

I tried "true" instead of "yes", no change.

[HALUI] for all the MDI_COMMAND stuff is in the main ini file now.  It shows up 
under the HAL meter- but are always false.  I pressed every button on the mpg.

The jog.enable-x show true/false when selected.

So, what I'm seeing is that any button listed inside my xhc-hb20.hal file works 
fine.  But all the  [HALUI] and [XHC_HB04_BUTTONS] stuff is inactive.

Re: [Emc-users] Stepper Motors

[Gregg Eshelman]

One use of the term is for a stepper with an encoder for feedback. With the 
right driver they can act like a brushless DC servo motor.

If you had working configuration files, use them. regenerating them with 
PnCConf is going to be much harder. There are only a few minor differences
that need changing on the hal files when upgrading from 2.6.x to 2.7.x
and these are easy to do by hand editing the files

[Emc-users] Mesa 5i25/6i25 +7i76 problems with 2.7.4

[fritz]

In the process of upgrading every computer I have, I've come up against 
some problems with my cnc install.


I have tried 4 different linuxcnc installs;  2.6.12 at an intermediate 
stage, and 3 different 2.7.4 installs.  I've even tried building from 
source, so technically I've done more than just 4.


First, a i386 Debian Jessie install:
- from buildbot:  2.7.4-uspace
- from Jessie backports:  4.4 rt_preempt kernel

Second, a amd64 Debian Jessie install:
- from buildbot:  2.7.4-uspace
- from Jessie backports:  4.4 rt_preempt kernel

Third, an install using the current Debian Wheezy iso from linuxcnc.org, 
apt-updated to linuxcnc 2.7.4


My hardware:
- AMD E350 dual-core with integrated graphics
- Mesa hostmot2 6i25 + 7i76

The mill:
- Taig cnc micromill
- Huang(?) VFD and spindle
- Gecko 540 stepper driver

I went about upgrading and ended up on linuxcnc 2.6.12.  I 'rebuilt' my 
config using pncconf.  This had a strange result of that while the 
stepper and digital I/O were working, the 7i76 spindle output no longer 
worked.  I even tried doing a new config with pncconf, with the same result.


I saw that linuxcnc 2.7 was stable, so I did an install on a separate 
drive for that.  I installed linuxcnc 2.7.4 for uspace.  I carried over 
my conf file, and rebuilt the config using pncconf again.


Now, the VFD output works, the digital I/O works, but any axis movement 
results in a following error.


There *is* stepgen output, because I have one stepgen output as the 
charge pump to the Gecko 540, and it clearly indicates when it is enabled.


What is really funny is that even if I increase the following error by 
orders of magnitude, this merely delays the following error, and 
produces no stepper motion at all.


How does linuxcnc make a following error with open-loop steppers?
How would linuxcnc be able to setup the charge pump stepgen, but not my 
XYZA axis?


Attached is my config files, and one session of verbose debug output.

My next move is to go back to some earlier linuxcnc version, but I'm not 
sure which one, yet.

You may want to put that in its own file, with a suitable name, and then 
source "suitable" name.

But OTOH, I have not done something like that (sourceing a file, which 
when done, essentially is identical to opening  up a small gap in the 
first .ini file and inserting the contents of the sourced file at that 
point in the first file, but I haven't done that myself except in hal 
files.  Laziness or my don't fix whats working attitude, flip a coin. :)

But it stands to reason it should work, at least till it throws it back 
at you in a meaningfull error message.

Re: [Emc-users] Question on DM860 stepper drivers

[Peter Homann]

Hi,

One of the advantages of Geckodrives over other drives is that they morph from 
microstepping to full stepping after the speed gets above a
  a few RPS.

That way, at low speed you get very smooth motion, and at high speed the=re is 
no torque lose due to microstepping.

BTW, microstepping does not combat resonance, specific functionality in the 
stepper drive is need to address it which all Geckodrives have.

Cheers,

Peter

[Emc-users] John T's Plasma o ?

[Jim Craig]

John,

I have been looking at your o subroutine. I plan on using it 
on the plasma cutter I am building with a buddy. My question is what are 
typical values that you are using for pierce height, pierce delay and 
cut height?

Do you switch to THC after the o subroutine? If so what are 
you using to toggle the thc.enable pin? Are you using an M62-M65 command 
to to toggle the thc.enable?

Thanks,

Jim

Re: [Emc-users] Can't get XHC-HB04 MPG to work

[dannym]

Sorry I didn't type the complete sentence: "So you're saying [HALUI] in a 
supplemental .ini file won't work?" was what I was shooting for.

Looking over the other stuff.  This looks like a GREAT help!

Is it ok that [XHC_HB04_BUTTONS],[XHC_HB04_CONFIG], [EMC], and [APPLICATIONS] 
are still in that layout20.ini file and not the main .ini?

There is already an [EMC] in the main .ini:
MACHINE =   HM2-Stepper
DEBUG = 0

layout20.ini additionally has:
[EMC]
MACHINE =  xhc-hb04 layout2 

Is this ok?  Do they just combine into what's effectively "MACHINE= HM2-Stepper 
xhc-hb04 layout2"?

Its not losing sync unless it throws the following error, and halscope if 
I catch it right, show a huge ringing as it errors, when it ran 
perfectly on the previous peck with no ringing.  It may occasionally be 
triggered by the .0008" backlash offset application shortly after it 
crosses the zero velocity mark, but far more likely will occur at the 
end of the g33.1 invocation after its unlocked, and the spindle is 
returned to fwd, while the z is being run back down to starting point. 
That motion is only restricted in delta v by the ini files max_accel 
setting.  And faster accel's seem to reduce it, most of the time.

Now, I have got to boogie and take care of some honeydo's involving 
replacing a single tub laundry sink with a double tub, and giving a 
dehumidifier that has been draining into that sink staining it to beat 
the band (its a $#@^&*$ plastic casting that weighs about 5 lbs) and 
needs lagged to the wall to keep it from busting its drain plumbing 
loose, getting a drain connector assembly that will let me drain the 
dehumidifier like is was a garbage disposal, in addition to acquiring 
some garage door cable pulleys and a long spring assortment and some 
metal to make pulley holders from.  Springs to be screen door and 
bigger. I may have to goto the lathe and make me some anchor knobs to 
hook the eyes of the springs up for easy changing, until I hit the 
balance point where it stalls at the same speed going both ways.

Later folks.

Thanks Jon

Not quite true, you can look at the step/dir signals with halscope (by 
looking ta the assosciated GPIO input pins), but you will not see much
on the step signal unless you have a very wide step pulse width
(or quadrature mode)

If you think there is step generator misbehaviour, the best way to check is 
via the following error, its not difficult to get the error less than a
very small fraction of a step (say 1/100) with proper tuning.

For software stepping, halscope is neat, but the 5i25 does not expose the 
step/dir signals for halscope perusal so a real scope or better yet the 
speaker is needed for this.  And its an idea I hadn't thought of to try, 
thanks Jon.  The ear is a fantastic device for hearing odd sounds that 
aren't supposed to be there!  The eyes are overloaded trying to analyse

Best guess is that the action from the jog wheel kit is not all properly 
linked in your hal file. Clear dmesg by running it as root 
with "dmesg -c", then run LCNC and stop it after its finished loading, 
then run as root, "dmesg". Screen copy it to get a list of everything it 
found, then check your hal file to see if its in there, both as a source 
for a "net" "name" "source_of_sig" "where_it_goes". The latter can be a 
space/tab separated list. If the list is too long, add another 
identical "net name" line anyplace below the first one, and continue 
your list of "where_it_goes".  Hal will append them when the duplicate 
net name is found later.

Gene,

I think he is referring to "Auto Tune" function that is activated by toggling 
DIP switch #4
(see the bottom of page 8)
http://www.americanmotiontech.com/upload/Manuals/DM860m.pdf

No, idea what it does or how. (no experience with these drives.)

That leads to a different driver, one I've never seen advertised yet, 
which reads as if it may be "next generation" software in it, says auto 
tune, which the MA860 has none of.

Its also, about $132, 2x the MA860.  What I just ordered may be better, 
and since I ordered a dual shaft motor, I can put a damper on it.
At 4.4 mh connected bipolar-parallel, compared to the 23mh of this one, 
it ought to fairly scream for rapids once I get the counterweight 
springs sorted.

Not in my experience Tomp. If the belt is loose maybe, but loose 
belts=backlash, lots of it. The way my toy mill is setup, driving the AC 
ball bearing mounted nut, I'd guess I have 30+ lbs of tension on the 
belt, and I can adjust the nut pair for less than 2 thou of backlash 
total.  Thats also with the ball bearing wheelbase stretchers that about 
triple the "wheelbase" of the vways on the head's sled/gib setup. 
Virtually no z stiction now.  If I note some when its moving slow and 
silent, a shot of vactra on the ways and a quickie full stroke run to 
distribute it will stop that for several days.

FWIW, I am seeing this same effect on the G0704 when the gibs are snugged 
up to stop any side to side head wiggle.  Same cure, I keep an oiler 
loaded with vactra 68 for that within reach. But that observation was 
made when the Z nut holder was coming loose too.  Not noticed since I 
took a torque wrench to those 2 screws that marry the nut holder to the 
carriage. I still lube it before any real work is to be done.

That leads to a different driver, one I've never seen advertised yet, 
which reads as if it may be "next generation" software in it, says auto 
tune, which the MA860 has none of.

Its also, about $132, 2x the MA860.  What I just ordered may be better, 
and since I ordered a dual shaft motor, I can put a damper on it.
At 4.4 mh connected bipolar-parallel, compared to the 23mh of this one, 
it ought to fairly scream for rapids once I get the counterweight 
springs sorted.

Where do you program the microsteps it uses?  Ah, found it, $24 optional 
plugin card and that brings it up to $166 USD + ship.  Ouch.  I can beat 
that, self powered, 9.8 amps, the usual microstep setting dip switches:



for $177.  At one point yesterday I had that driver and a 920 oz 4,4 mh 
motor lumped together, for about $220 IIRC and if I can find it again, 
will order it. ebays search function sucks.

Couldn't find the kit with that driver, ordered separately, about 10 
days. $265 IIRC. No clue what the motor coil peak volts is but its got 
to be a heck of a lot faster than the 1600 oz/in, 23 mh 3.5 amp snail, 
with a 60 volt 5.85 amp, + an MA860 driver 3 piece combo in there now.  
Maybe even faster than the XY setups on it, they peter out at about 60 
ipm if asked to go clear to the end of the x ways.  And I'll go see what 
I can get from tractor supply in the way of pulleys, springs and bars to 
hold the upper end where the pulleys will live.  Just like on my HF toy, 
but a heck of a lot neater looking I hope. I might even get 4 pulleys so 
I can stretch the springs forward to get a hold on the head somewhat 
closer to its CG. Slim possibility of attaching the pulley mounting bars 
on angle stock on top of the motor if the motor has any tapped holes on 
the top face. TBD of course. Now I have a 15" abrasive saw I didn't have 
when a cobbled up the toy mill so I can cut steel a little neater.

Thanks John.

Yes, but the GPIO on the 7i76 is smart-serial. This is why I was
suggesting using some 5i25 pins wired as step/dir on the 7i76  as GPIO
for the purpose.

Look at PID..error, it will magnify the deviation. 
Although, I guess, if the PID output is only varying by 5%, 
then the step rate should not be varying more than that.  
That shouldn't be the cause of loss of sync of the motor.

You can also hook up an old PC speaker with a 150 Ohm 
resistor in series to the step signal and listen to it.  The 
ear has a great system for picking out multiple 
frequencies.  Since my (Pico Systems) stepper board is 
essentially a servo, where the computer sends a velocity, 
step pulses are counted as if they were coming from an 
encoder, and then run through the PID hal component, bad PID 
parameters can cause nasty frequency hopping at certain 
speeds.  So, I listen to it and twiddle until I get smooth 
tones that sound like turning the dial on an audio 
oscillator.  (You can also do this with Halscope.)

Re: [Emc-users] Can't get XHC-HB04 MPG to work

[dannym]

So you're saying [HALUI] in a supplemental .ini file?  
Alright, that sounds like the problem!


Are there more elements which will only work if placed in the main .ini file?

layout20.ini has [XHC_HB04_BUTTONS], [EMC], [HAL], [XHC_HB04_CONFIG], and 
[APPLICATIONS].

I'm guessing [EMC] and [HAL] need to be in the main .ini, right?  What about 
[APPLICATIONS]?


[XHC_HB04_BUTTONS]
step= xhc-hb04.stepsize-up
spindle = halui.spindle.start

So, the step size did not go up when I pressed the button.  Spindle didn't 
start.  Those are NOT an MDI, so I still have another problem, right?  What 
might it be?

Those pins are created by halui based on the MDI_COMMAND entries in
the [HALUI] section of the main INI file.

So, you need to find or create a [HALUI] section in your main .ini
file (as many as you need) and each one will define a single-line
G-code command that will be run when the corresponding HAL pin is
triggered.

http://linuxcnc.org/docs/2.7/html/config/ini-config.html#_halui_section

For more complex actions your MDI_COMMAND can be a subroutine call
such as O CALL

The hostmot2 driver exports a "write_gpio" function exactly for this 
kind of use case.  It updates just the gpios, runs quickly, and is 
intended to be called from a faster thread.

can a damper be put on the far end of the transmission

may not be optimal but may help

Two things...

It used to mean that the motor had a permanent magnet rotor.

It now sometimes gets used to refer to a closed-loop step-servo, where
the stepper motor is driven as a 50-pole brushless servo.

In my playing with the 2m542's and 400+ oz/in nema 23's, 4 is noisy, 8 is 
much quieter and 16 is very quiet. I can go back to 8 on this just to 
test.  At 8 I can hear it even at 1 rps.  Single shaft motors, so I 
can't put dampers on any of these.  Darn it.  Dampers on the toy mill, 
and on the lathes z are a huge help, tripling the rapids capability.

Halscope shows a very small amplitude ripple, perhaps 5% of the instant 
output at pid.z.output to the 5i25 when this is going on. This while the 
peck loop using g33.1 is cutting air. Certainly not a rail to rail jog 
that it sounds like.

My thinking is that this driver is keeping the math correct, but is 
switching off the microstepping long before rotor inertia would result 
in a smoothed move.  The 2m542 drivers doing the x/y, show no evidence 
of doing that.  I have had the microstepping ratios set for everything 
above 4, currently at 64, and the only noticeable change is from 4 to 8 
to 16. At 8, even slow movement is audible, at 64, 1 rps is dead silent. 
At 3 rps its sounding rough, at 5 rps its rattling tools off the table.  
Changing the current up and down half an amp has little effect on this 
noise.  I haven't looked at a motor phase from the driver as I've read 
that the scope probes capacitance can blow the driver.  Since the probes 
are 10x, maybe 16 pf's, that sounds like an old wives tail as its happy 
driveing 9 feet of a shielded cable to the x motor & 6 feet to the z 
motor.

So that explains why I'd like to change the driver for another type, but 
thats an expensive way to test...  Thats why I am asking for other users 
experience with this far more expensive driver before I have paypal 
issue the payment.

The halmeter is pretty close to real time, so if you can find that 
signals name in the show-hal, halmeter can tell you whats going on in 
millisecond response times.

This might be a case for a rockhopper run, but that, by the time it is 
blown up enough to be readable, will take posterizer set for 6 to 12 
pages on a complex machine to show it all legibly.  That can be a quite 
informative troubleshooting tool.  Rockhopper has one gotcha, it does 
not record and draw, a pin with no target defined.

And many times, a sudo dmesg -c, start linuxcnc, then a fresh dmesg might 
show you errors.  All are handy tools.

Those pins are created by halui based on the MDI_COMMAND entries in
the [HALUI] section of the main INI file.

So, you need to find or create a [HALUI] section in your main .ini
file (as many as you need) and each one will define a single-line
G-code command that will be run when the corresponding HAL pin is
triggered.

http://linuxcnc.org/docs/2.7/html/config/ini-config.html#_halui_section

For more complex actions your MDI_COMMAND can be a subroutine call
such as O CALL

Which output pin are you trying to drive? The IO pins on the 7i76 only
update every 1mS.
Haslcope (and the PWM function) are updating every 100uS.

There is this (which is somewhat out of date in that it does not
mention the newer cards, like the 5i25, which have a flashed-in
firmware and do not need firmware download when LinuxCNC starts)
http://linuxcnc.org/docs/2.7/html/drivers/hostmot2.html

And then there is the up-to-date but less well-written:
http://linuxcnc.org/docs/2.7/html/man/man9/hostmot2.9.html
(The "config modparam" section is the part that really matters, you
typically don't use any options on the "loadrt hostmot2" line in the
HAL file.)

I would guess resonance or step signal have to toggle between two different 
frequencies but have no experience. An oscilloscope would tell if there are 
problems with the step signal. I can also tell if stepper driver behave as 
expected.

Hello Andy,

Yes, I am using the software PWM component output to MESA fpga card. Still, I 
can't understand why I can't get the correct output on FPGA, although I am 
getting on HALSCOPE ?

Why hardware PWM and new firmware is needed and how can I get it ? 

Also, is there any tutorial to " how to disable one of the step/dir channels" 
on 5i25  ?

So, you are using software PWM with a Mesa FPGA card?
It would be better to use hardware PWM in the FPGA, but that might
need a different firmware.

The GPIO on the 7i76 is only updated once per mS, at the servo-thread rate.

There is an option to control _5i25_ GPIO at a faster rate by running
the hm2_5i25.0.write_gpio function in the faster thread.
This is not the same as the 7i76 GPIO.
By default all of the 5i25 GPIO is allocated. What you could do is
disable one of the step/dir channels and use that as GPIO (the
step/dir channels are wired direct to the 5i25, the 7i76 channels are
addressed by a serial interface and handled on the 7i76). Once you
have disabled the step generator and worked out which 5i25 IO pin that
corresponds to (the dmesg output will tell you) then you can run
software PWM to that pin.

However, I think that this would also disable all the step/dir
channels on the 7i78. So it would be better to disable only one
step/dir channel for this purpose.

Better still would be a custom firmware with a PWM generator connected
to one of the step-dir pins.

Alternatively, another user recently connected the 7i76
spindle-control potentiometer output in place of the potentiometer of
one of these devices to run an RC ESC:
http://www.ebay.co.uk/itm/Mini-3CH-Servo-Tester-Servo-Consistency-Master-Tester-for-RC-Helicopter-UK-/291289742212?hash=item43d238bb84:g:kMgAAOSwrx5UXGe~
and apparently it worked well.

[Emc-users] Can't get XHC-HB04 MPG to work

[Danny Miller]

It's loading without error.   The LCD works, the handwheel does jog the 
axes, and the selector knob does change the axes.  But none of the 
buttons function, including the Step Size, so it's stuck moving by 0.001".


I have LinuxCNC 2.7.4  and the Linux Preempt-RTK.  I did what was 
specified about adding USB permissions.


So 7i92_general_XHC20.ini is the main ini file. I added a 
[XHC_HB04_CONFIG] section which gives setup parameters. I added HALFILE 
= xhc-hb20.hal to the [HAL] section.


xhc-hb20.hal is a renamed copy of a modified xhc-hb04.hal. The homing 
routines don't exist, nor does an A-axis, so that's removed. Loadusr got 
changed to the local name "loadusr -W xhc-hb04 -I xhc-hb04-layout20.ini -H"


xhc-hb04-layout20.ini has layout2.inc added into it directly. For 
whatever reason layout2.inc didn't seem to be loading correctly into it 
so I just added it.


The HAL viewer does show there's an XHC section.  However (I'm not in 
front of the machine now) IIRC the halui.mdi-command-01 etc didn't seem 
to exist under halui.  I found what should have been the STEP++ pin  but 
it didn't show TRUE when I pressed it.  But I'm not sure how that works, 
if it's a momentary press and I just manually reload the HAL status I 
would probably never catch it.


Thanks,
Danny
