[Emc-users] MESA card suggestions

[alanmthomason--- via Emc-users]

Hi There.

 

I am looking for a suggestion for the best MESA card to be used with 

an ethernet connection

4axes 

Teknic servo / stepper taking a step/direction input of 5 to 24V

Ideally this would be in a format that I could mount in a simple enclosure.

3digital inputs per axis, so 12inputs

1 additional digital output.

 

I will be using a fresh build of linuxcnc on a 64bit Ubuntu platform.

 

Thanks very much,

Alan

[Emc-users] Stepping through linuxcnc

[alanmthomason--- via Emc-users]

Hi There.I am looking for guidance to build linuxcnc in a way that I can
step through it.  I can build currently, but in trying to understand the
underlying code I was hoping to use a debugger to step through it.  

I could not find any flags in the configure -help that looked right.  

 

Thanks so much, Alan.

Hi Gene...

I might have to leave my path of using the beaglebone for now and switch to
the Raspberry Pi.  Do you have any notes on how you reached your success?
For instance, where did you get or how did you make your real time image
etc.  Or perhaps just point me to a recent set of notes for the
RPi/LinuxCNC.

Thanks very much,
Alan

Success Andy, built, installed, running. 35 minutes on my rpi4b.

[Emc-users] 12-M99-endless-main-program test fa

[alanmthomason--- via Emc-users]

Hi There.

 

When I build linuxcnc and then run the standard suite of tests, I see dozens
of tests where a line output says Running test XXX.  After about 100 of that
type, I see the interp/m98m99/12-M99-endless-main-program test fail as
indicated below.  

 

My questions are 

1.  Are the preceding ~100 tests successful since there was no further
output.
2.  For the test that fails, interp/m98m99/12-M99-endless-main-program.
a. does everyone else see this test succeed?  
 b.  Any thoughts on what issue this might point to on my system?

This is a BeagelBoneBlack

Hi There.I'm trying to work through setting up linuxcnc on a beaglebone
black.  I've run the latency-test, with results that are not looking
good.has anyone else run this test with a Beaglebone black?  Is there any
way to improve results.

 

Thanks very much.Alan

It might be automatic, the modules should be built for any "uspace" config:
https://github.com/LinuxCNC/linuxcnc/blob/master/src/Makefile#L995

If you install "gpiod" does "gpioinfo" work?
If so, then I am currently working on a driver that uses libgpiod.
That might work for you (though not at the moment)

[Emc-users] LinuxCNC build on BeagleBoneBlack

[alanmthomason--- via Emc-users]

Hi All.

 

I am working on building LinuxCNC on the BeagleBone Black.  It does build,
but the test sequence does not complete and I see some fails in the output,
and the test sequence hangs.

 

Questions

1.  Do these test fails indicate known issues or point to problems that
I need to address before going further?
2.  When I perform the configure, is there a way to specify the BBB?
I'm trying to figure out how the compile process would bring in
src/hal/driver/hal_bb_gpio.c
3.  Has anyone set up a configuration (hal/ini) for the BBB that I can
use as a guide?  
4.  Does operation on the beaglebone black require a dtb file to be
loaded to specify the needed pins as input/output?

 

Any help would be most appreciated.  

 

Best Regards,

Alan

 

Background:  We currently use Machinekit on a BeagleBoneBlack using an image
from 2019.  There are some issues, for instance sometimes we see a shared
memory error.  So, my hope was to be able to compile from source.
