La salida 4 que tiene mejor aislamiento es dc o ac  por que he puesto un ssr de dc y no corta se queda en contacto aunque no este dada la antorcha de plasma

You mean the ini file or what ?

Difficult to troubleshoot. Please attach your zipped config folder so we can see how things are setup.

Hello everyone,I’m facing a persistent issue with implementing a Python-based M6 remap in LinuxCNC 2.9.4 running on Debian Bookworm. No matter what I try, LinuxCNC always reports that my remap function is “not a Python callable function,” even though I have followed all the official documentation and community advice.Details:

• Configuration:
  • In my INI file, I have:
  • [RS274NGC]
    
    
    PARAMETER_FILE = linuxcnc.var
    RS274NGC_STARTUP_CODE = G21 G40 G90 G94 G97 G64 P0.025
    REMAP = M6   python=my_m6_remap_function modalgroup=6
    
    [PYTHON]
    PATH_PREPEND=/path/to/my/python/scripts                            
    PATH_APPEND=/path/to/my/python/scripts  
    TOPLEVEL=/path/to/my/python/script/m6_tool_change.py
    
    The Python file is in the correct directory, and the function name matches exactly. The function signature is:
    •     def my_m6_remap_function(self, **words):
              # minimal test code
              print("Hello from  REMAP")
              return INTERP_OK
      
      
      
      I have tried different function names, ensured the function is top-level (not inside a class or another function), and removed any __init__.py, .pyc, or __pycache__ files.File encoding is correct (UTF-8/ASCII), and permissions are set properly.Result:I always get the following error:
          'my_m6_remap_function' is not a Python callable function - ...:REMAP = M6   python=my_m6_remap_function modalgroup=6
      I have tested this on multiple machines, with fresh configs (including a clean Axis config), and even on a different PC – always the same result.Remapping using ngc (subroutine) works perfectly.
      I can import linuxcnc in Python 3 without issues.
      I have tried examples from stdglue.py and the forums – same error.Environment:Debian BookwormLinuxCNC 2.9.4 (from official repositories)Python 3 bindings are present and workingNotes:I suspect this is either a bug in LinuxCNC 2.9.4 on Bookworm or a missing package/feature in the current build.
      Downgrading to an older distro or using Python 2 is not a practical option for me.I need Python remap for integration with a custom PyQt5 GUI and an Automatic Tool Changer (ATC).Has anyone else encountered this issue or found a practical solution?Is there a way to enable Python remap support in this environment, or any workaround besides using ngc?
      Any help or suggestions would be greatly appreciated!
      

El thcad2 no lo se por que no se como comprobarlo

he comprobado lo de step/dir 04 y funciona perfectamente 

Hi Patrick,

so, regarding the encoder resolution I have come one step further. It actually is configurable and the default value is 4000 counts/rev.
I suspect that the drive doesn't have a "real" hardware encoder but uses hall sensors or other electronic tricks to know/estimate the position. Thus the resolution can be set kind of arbitrary and is dependent on the accuracy of the sensors.

I was able to set the resolution to 10_000/rev without problem. But the question remains how accurate that actually is and if such a high resolution makes any sense. I think I'll settle with just 1_000/rev which will still give me an accuracy of 10µm in combination with my 5mm/rev ball screw.

If you're interested in more details, let me know and I will share what I found out.

Regarding the XML configuration I'd be interested to see what you came up with.

Good luck with your exams,

Uwe

 

The THCAD connection should not have any effect on the 7I96S unless there was
some kind of issue with the 7I96S side (encoder side) wiring, as the plasma
(Analog input) side of the THCAD is completely isolated from the 7I96S.

Is the THCAD2 in the same case as the 7I96S?
 
 

got a new card didn/t help. same messages. I finally just install version 2.9.4 and everything works.
