Category: General LinuxCNC Questions

after a long struggle to get a debian system working together with wifi, network, linuxcnc and rt kernel on a newer n100 intel nuc-like computer, im finally at the get linuxcnc woking with my setup phase. i havent tinkered in linux for about 10 years, after linuxmint that is not really needed anymore for basic use cases.
i downloaded this configuration for linuxcnc and mr1. github.com/alexphredorg/mr1. i can't get it to work it errors out and quits, i don't know enough to figure out what is missing or broken. ill get a log later when im back with it.

my current software setup is
base 2.9.4 iso, added driver for usb wifi, installed software listed on the readme.txt in the home folder and mods from the intall guide found in the github link above relating to mesa. nothing more kept it as close to stock as possible before swapping to newer kernel etc.
hardware is a 7i96s. i can ping it and setup the most basic axis config with only xyz and spindle and can run the included g-code(no i/o hooked up).
most of the sims work, the ones from installing from the list in the home folder do not work.
im not sure if i need to sent something to the mesa card, i have not found any instructions or mention of this, or if something needed is missing from the enviroment.
as for the electrical end i should be good maybee ssome questions on specifics when i get there.

You could also copy the macros directly from the gmoccapy sim config (untested):
src_fpath = os.path.expanduser("~/linuxcnc/configs/sim/gmoccapy/macros/change_g43.ngc")
dest_fpath =  "%s/macros/change_g43.ngc" % base

os.makedirs(os.path.dirname(dest_fpath), exist_ok=True)

shutil.copy(src_fpath, dest_fpath)

That way you do not need to have duplicate gmoccapy specific files in the pncconf sources.

I think it's time to update the first post of this thread, It's not working straight forward anymore even with 2.9.3, I had to jump on the last post to find a way to let it work. Also tried 2.9.4 and it's not working. Thanks for your time, when it works It's so satisfying

Yeah, sounds like it's a 5V PWM input.
 
There is 5I25 +7I76 firmware that replaces one stepgen (stepgen4)
with a PWMGen:

perhaps for now adding this to the stylesheets will suffice:

   padding: 2px 25px 2px 20px;
   font: 24pt "Lato Heavy";

Hello,

I am trying modify PNCconf:

Here github.com/LinuxCNC/linuxcnc/blob/1c72d4...nf/build_INI.py#L176 I added:
        if self.d.frontend == _PD._GMOCCAPY:
            print("SUBROUTINE_PATH = ./macros", file=file)
            print("REMAP=M6  modalgroup=6 prolog=change_prolog ngc=change_g43 epilog=change_epilog", file=file)
            print("REMAP=M61  modalgroup=6 prolog=settool_prolog ngc=settool_g43 epilog=settool_epilog", file=file)
            print(file=file)
            print("# the Python plugins serves interpreter and task", file=file)
            print("[PYTHON]", file=file)
            print("PATH_PREPEND = ./python", file=file)
            print("TOPLEVEL = ./python/toplevel.py", file=file)
            print("LOG_LEVEL = 0", file=file)

It works.

Then I added folders macros and python to /linuxcnc-master/src/emc/usr_intf/pncconf

I want copy it to new configuration, so I added here github.com/LinuxCNC/linuxcnc/blob/1c72d4...conf/pncconf.py#L389 :
            if self.d.frontend == _PD._GMOCCAPY:
                dirbase = "%s/macros" % base
                dirpython = "%s/python" % base

                if not os.path.exists(dirbase):
                    shutil.copytree('/home/zdenek/linuxcnc/linuxcnc-master/src/emc/usr_intf/pncconf/macros', dirbase)
                
                if not os.path.exists(dirpython):
                    shutil.copytree('/home/zdenek/linuxcnc/linuxcnc-master/src/emc/usr_intf/pncconf/python', dirpython)   

It works, but I dont want absolute path: /home/zdenek/linuxcnc/linuxcnc-master/src/emc/usr_intf/pncconf/

Can I ask for help?

Is good idea has the files in src folder?

It works now!


Is there some sort of step-by-step beginner's guide or something?

There should be.

It would make life so much easier for beginners.

Yes, the G5x button works when long pressed, thanks.

Well, I thought you could call up a calculator-like window, something like that:

 


 

Ahh OK I get it - interesting.

@PCW-
I thought about using orient.comp with it's own PID to do just what you suggested (get it close before re-linking the main PID), but caxis.comp interferes with orient (I think).

Cooking up a 3rd get-it-close PID is a fantastic idea.  I'll have a go at it.

@Aciera-
Writing a python comp for me was more than I'd expected (or deserve), but I suspect it'd take longer to explain things and bring me up to speed than to just whip something up.

I'll try to digest what the comp is doing and test it out.

Thank you both very much.
