How to make M1** execute Gcode

I have not played with it at all but Python 3.10 which is shipped with Debian Bookworm where Linuxcnc can be installed using:
sudo apt install linuxcnc-uspace
Now includes a case statement:

Its enought to make me want to adopt Bookworm as my new best friend.

Hi,
I dont knopw if this will help
but I use M1xx to move
Theres a comp i use
and it changes modes from auto to Pause
and the motion destination is set by a seperate Mcode
My effort is for EDM
Yours is PickAnPlace
But the use of MoveWhilePaused is similar
Mine uses a single axis but can be modified
Yours would like have motion with some waypoints
that is, move UPtoClearHeight then XYtoPartWanted then DownToGrabPart then XYtoOverDest then DownToPartDestHeight
All this could be done using machine coordinates

This idea does NOT use Gcode, just destination positions
This code does NOT use PID Accell/Decell
This idea ends at same position where it began
That allows the mode reversal back to Auto without any jerk.
I attach the comp code and the hal wiring as png's

in python script use
import sys, subprocess

then build your command string
  like  cmdstr = "halcmd setp testEtab.0.mypin"
and add the value to be set
  like cmdstr = cmdstr + str(myval)
then have the system exec the cmdstr
  like
    subprocess.call(cmdstr, shell=True)

loop that recipe thru all the pins to be set

hth tomp

watch in action

  subprocess.call(strg5, shell=True)
...
 

Another option might be to an O-sub program call instead of an M1xx code.

 So far my end result became switching to a M201 code using python see the link if you want to see how it works.
