Re: [Emc-users] Pyvcp scripts.

[anders wallin]

Hi Ian,

The scale widget ('slider') is a light wrapper around the tkinter scale 
widget and can be oriented either horizontally or vertically with

HORIZONTAL  or VERTICAL, Pyvcp doesn't deal 
with that, 
it's just passed directly as a parameter to the tkinter object.


The bar widget you want inherits from canvas and all the drawing is done 
in pyvcp_widgets.py, but there is no code there right now that would 
recognize an  tag or would do the drawing vertically.
Learn a bit of Python, Tkinter, and HAL and you could look at the 
pyvcp_bar() class in pyvcp_widgets.py and figure out how to do it yourself!

Re: [Emc-users] Repost: Teach with joystick.

[Alex Joni]

Hi Dan,

the teach-in function that is included in emc2 is a "hack" that is used to 
save position for some puma-typed robots.
Basicly you launch the teach-in script (once emc2 is running), and when you 
push teach (if my memory serves me right) it saves the current position 
(both in joint space and in carthesian space).
I'm not sure if this is useful to you, as you would have to write the G-code 
for those points.

Regards,
Alex

Re: [Emc-users] Repost: Teach with joystick.

[Daniel Kavanagh]

Hi Alex,

  That sounds kind of limited :(

  What I really want to do is 5 or 6 axis control with joysticks,
recording all the while.

  I am gathering the parts to make a 6 axis gantry style welder. The
setup would be like a 5 axis router with the sixth axis being like a
spindle to rotate the torch.

  The thought of doing CAM and gcode for that just seems like a total
nightmare. Think zig zag bead as you travel around a tube notch.

  Leaning to weld with joysticks however seems like a video game! Put a
camera on it! Dual monitors.awesome!

  I realize this is complicated, joystick jogging is not real time. I
was thinking you could use hal streamer and maybe log it and then play
it back? Automate pressing the teach button and add some code that
converts it to gcode?

  I don't know. I do know that I can build the machine and I really
would like to automate some of my welding.

  I am working on my plasma tube notcher right now and the welder is the
next project.

  Thanks,
  Dan

Re: [Emc-users] Repost: Teach with joystick. (Welding)

[Craig]

Two comments:

1.  Software to Generate basic G-code from a sequence of positions 
should not be a very difficult problem. 

2.  It would seem to me that welding a good bead (not spot welding) 
would require either very consistent materials or some feedback on 
puddle properties.  Puddle properties could be measured from a visual 
and/or IR image.  Measuring welding voltage/current might also be useful.
(It has been some years since I considered this problem, so good 
technical solutions may since have been found.)

I just tried the 2.2.6 sim/lathe and it works AFAIK. You might try a dual boot

then with the internet connected wait for the update icon to flash and update

2.2.6... then try the sim/lathe.

RT-Linux is pretty much a dead project from what activity I have seen. The 
last patch I saw was for a very early 2.6 series kernel and possibly 
experimental. A quick look at the WindRiver overview suggests that they use a 
2.6.14 kernel, but I doubt anyone (here) uses it.

> Are there maybe some RT-Linux systems in the EMC2 build farm?

There was a 2.2.x series kernel patched with a very old RT-Linux version, but 
your driver(s) won't compile on anything other than 2.6.xx.

> Does anyone run EMC2 on RT-Linux?

RT-Linux support is a dead end, rtapi for RT-Linux does little more than add 
to the general bit rot.

the spindle / tooling arent a draw bar like on a bridgeport, they have

the amps look identical at a glance, im on lunch break so im tryin to keep
it quick.  the motors are all directly connected to the amps, thats why i
thought to send the quadrature to both emc and the amp.

there are aluminum strips along the ways, i havnt seen any connectors on
them where they would be scales, but it's a possibility.  If i go to the
town where the machine is I'll try to remember to get the camera and some

  Yeah, consistent materials and a solid jig is what I am hoping will do 
the trick. Weld seam tracking and all that jazzy stuff is probably 
overkill, but can be added if necessary.

  I think if EMC can record my welding with the joysticks accurately 
enough, dwell this long at this amperage, feed this much wire, etc. all 
will be well.

[Emc-users] Parallel Port Test

[Andrew Ayre]

Hi, Is there an easy way of testing the parallel port without having an 
oscilloscope? A friend's controller board started smoking (Z axis driver 
chip) and now none of the axis work. It's pretty easy to replace chips, 
check solder joints, etc. but how to test the parallel port?

thanks, Andy

Re: [Emc-users] Parallel Port Test

I usually use a wire to connect an output to an input, then use halmeter
to see if it toggles.
But in some cases this might not work (needs pull-ups or such)

Oops, I got the impression that you didn't use pull studs. I just sold
some NMTB40 holders on eBay for less than $20 including shipping. Your
CAT40 is much more common. I would think that if you shop around on eBay
or Craig's List, you could get the same or better deals.

In most cases like this, you would run wires from the encoders to both
the amp(driver) and EMC. The problem is in how EMC would use the
information. It could be used for the position display and if needed for
motor control feedback. Knowing how your drivers work will determine
that. What I would be looking into next would be to trace the
connections that go from your driver to your controller to see how many
wires there are and see if they are labeled in a useful way.

I wish I had more to offer. This doesn't seem to be a project for a
beginner. I wonder if you would be better off selling the machine and
getting something like a Shizuoka ST-N which can be had for around $1800
and would be an easy conversion. Of course the parts you are making
would have to fit the workspace. Shipping is a big problem too. You will
get the best price for you machine if you have a shipper and lift
prearranged and you can wait for the best offer.

[Emc-users] steplen, etc

[Emory Smith]

Are steplen, stepspace, dirhold and dirsetup in nanoseconds or microseconds?
For instance, is "setp stepgen.0.stepspace 1000" absurdly wrong?
Or does that mean 1 microsecond?
Did the specs change somewhere between versions?

Ubuntu 8.0.4/EMC 2.2.6

Thanks,

I don't want to install at this stage and risk screwing up a working
machine, I've had bad experiences in the past with Linux and don't want
to spend too much time on something that may not be suitable anyway. I
simply wanted to look at the user interface and EMC turning
capabilities.

An alternative CNC lathe solution.

[Emc-users] Tool orientation in AXIS

[juanjo]

Hello Guys.

Anubody Kown if a way to change the orientation of the Tool in the
the AXIS gui?

i like to see the tool in a horizontal way (not vertically)
like a Horizontal machining center.

I haven't followed this thread completely, but ... I think you can Live
boot your Windows PC to EMC2, when EMC2 asks you to select a
configuration, it may ask you if you want to make a copy of the
configuration to your home directory, which at this point is on a
RAMdisk (?). You can go to your copied configuration and modify it to
your needs. Of course, you will lose this config when you reboot. You
may be able to use a USB stick (camera, mp3, iPhone, whatever) for your
config directory in which case your config would be saved(?). This way
you can do everything that a normal install can do without actually
installing. I don't currently have a PC to test this with. Does this
help or did I miss the mark?

Re: [Emc-users] New user new problem

[Greg Michalski]

Well lets see here - are you talking about an automated Z touch off plate with 
a script/macro of some kind that moves the tool to a certain machine coordinate 
and touches a plate, triggering the probe circuit and identifying the new Z 
offset value to use then returns to machining after finishing a manual tool 
change?  Or are you looking to adjust the tool table file and use that with a 
rigid holder system that maintains a repeatable Z?  Some details of your 
machine would be helpful - ie: R8 collets, Morse Taper collets, CATxx or NMTBxx 
holders, etc.

I know I have seen something of the Z touch off plate and a set of G-code 
commands that would be a starting point of a script/macro to set the Z offset 
but I'd need to do a bit of searching as I saw that well before I had my 
machine up and running and I haven't finished the basic stuff I want let alone 
gotten into more automation.  It's still off in the horizon for me.  Hopefully 
someone else can lend some more help.

Hi.
i have been playing with the tougth for a while, can you use the probe
function. in my case move to a position press a button conected to probe
in to record the coordinates and then go on to the next poss.. or if you
ned a track just get a switching signal to the probe pin, and then if
you adjust the speed of the switcing you would get as many coordinates
as you need to get a smooth mowement to a robot. could i be on to
somehing??

Re: [Emc-users] Stepper configuration

[Eric H. Johnson]

Sebastian,

I updated to the latest release, and started playing with hostmot2. I ran
the following commands under halcmd:

loadrt hostmot2
loadrt hm2_5i20 config="firmware=hm_5i20 num_stepgens=2 num_pwmgens=1
num_encoders=0"

I then did a "show pin", which returned no pins. Shouldn't I be seeing pins
at that point?

Thanks,
Eric



I've tried to describe how all this works in the hostmot2 manpage, take a
look at it and let me know what parts of it are unclear or incomplete.

Release.gpg

The others have different dates so I assume I dont want them.
Does .gz mean its compressed?

Or do I need them all?
Be kind its my first update.

The wiki seems to indicate that you need a .deb file. Do you currently
have Ubuntu 6.06 Dapper or 8.04 Heron?

Excellent, thanks for trying it out!  What you did looks almost right, the only 
problem I see there is the firmware part of the config argument.

There are several hostmot2 firmwares available for the 5i20, and the 
"firmware=" part needs to name a specific one, located where the driver can 
find it.  The hostmot2 driver uses the standard kernel firmware loading 
mechanism, which means the firmware must be accessible in /lib/firmware.

The first step is putting the firmwares where the loader can find them:

 If you installed EMC2 from the Debian package, the firmwares are already 
there and you dont need to do anything.

 If instead you checked out the CVS tree and are using run-in-place, you 
need to symlink the hostmot2 firmware directory to /lib/firmware with a command 
like this:

 sudo ln -s 
$HOME/my/emc2/sandbox/src/hal/drivers/mesa-hostmot2/firmware /lib/firmware/hm2
 (change the source path to point to your actual sandbox)


Once that's done we can pick a firmware file to load.  You can see the 
available files by looking in /lib/firmware/hm2/5i20; each .BIT file is a 
firmware file you can tell the driver to load.  The firmwares available in 
2.2.6 are:

0 [EMAIL PROTECTED] /home/seb>  ls -1 /lib/firmware/hm2/5i20/*.BIT
/lib/firmware/hm2/5i20/SV12.BIT
/lib/firmware/hm2/5i20/SVST2_8.BIT
/lib/firmware/hm2/5i20/SVST8_4.BIT

"SV12" means 12 servo channels.  "SVST2_8" means 2 servos and 8 steppers.  
"SVST8_4" means 8 servos and 4 steppers.  Either of the last two would work 
with the rest of the config line you specified; let's say you want SVST8_4.BIT. 
 You'd use a loadrt line like this:

 loadrt hm2_5i20 config="firmware=hm2/5i20/SVST8_4.BIT num_stepgens=2 
num_pwmgens=1 num_encoders=0"


Give that a try and let me know how it goes.  :-)

Oh yeah, and if it doesnt work, please attach the file /var/log/syslog to the 
next email.

That 1-4 KHz figure is an old measurement I remembered for 4-channel 
servo control (on the 7i43 board): read 4 encoder counts (counted by the 
FPGA), do 4-channel pid in emc2, then write 4 PWMs.

I ran some tests tonight on my development machine, a single-processor 
Celeron running at 2.6 GHz.  Please remember that the driver is still 
under development and basically not optimized at all: these figures may 
change in the future.

The values for "time" reported below is the average time taken by the 
function (measurement is approximate average of 10 or so random 
samples).  The values for "tmax" is the longest time taken by the 
function after a few minutes of runtime.  All times in microseconds.


7i43:

 pet_watchdog (or else it bites) time=47, tmax=57

 read (4 encoders, 4 steppers, 48 gpio inputs) time=245, tmax=260
 write (4 pwmgens, 4 steppers, 48 gpio outputs) time=235, tmax=637

 read_gpio (48 gpio inputs) time=37, tmax=49
 write_gpio (48 gpio outputs) time=35, tmax=46


So if we're just talking about reading & writing gpios, you can do that 
at about 7 KHz and still have 50% of your CPU time left over for other 
things.  Or 2 KHz if you want the watchdog enabled.


If I disable the steppers on the 7i43 (with config="num_steppers=0") and 
run it with 4 servo channels (and 24 accessible GPIOs), I get these figures:

 read time=191, tmax=203
 write time=190, tmax=239

That's about 1 KHz.


And just for fun, the numbers for the 5i20:

 pet_watchdog (or else it bites) time=6, tmax=13

 read (8 encoders, 4 steppers, 72 gpio inputs) time=52, tmax=62
 write (8 pwmgens, 4 steppers, 72 gpio outputs) time=15, tmax=27

 read_gpio (72 gpio inputs) time=13, tmax=42
 write_gpio (72 gpio outputs) time=5, tmax=12

OK, same problem as my PPMC line, then.  But, 1 KHz isn't fast

Very interesting!  I wonder if you can improve this by 
streamlining the driver.  I can do 4 axes on my USC or UPC board 
at about 100 us, on a 600 MHz Pentium II through the motherboard 
parallel port.  A safe 5 KHz.

Well, it certainly shows the effect of the parallel port on the 
7i43!

Re: [Emc-users] Tool orientation in AXIS

You could define a bogus B-axis and use a G0B90 .. but I'm not sure how nice 
that is

You need either :

http://www.linuxcnc.org/emc2/dists/dapper/emc2.2/binary-i386/emc2_2.2.6_i386.deb
 
(for dapper)

or

http://www.linuxcnc.org/hardy/dists/hardy/emc2.2/binary-i386/emc2_2.2.6_i386.deb
 
(for hardy - i386 - most likely)

or

http://www.linuxcnc.org/hardy/dists/hardy/emc2.2/binary-amd64/emc2_2.2.6_amd64.deb
 
(for hardy - amd64 bit machine - less likely, for this platform there is no 
LiveCD currently)

Alex
