How to make M1** execute Gcode

I did notice that when I looked at it's code . I wasn't exactly sure of it's purpose but I wasn't going to question. The end game for the
M-code will be it will use a P number to represent what feeder position to travel to and use a table file via either a .tbl  or similar.
That way any component offset can be entered into the table file and when The M-code and P number are entered the pickup
head will go to the exact position required . But that will be down the road. For now just having an M-code that I can enter
those offsets into will suffice.

I have another question for you andy . Why are only "if" statemants used and not "if" and "elif".?

Gotcha I didn't know if their was some specific rule of why you used only if statements. it was only when I looked up how to do Case Statements
in python that I discovered that python doesn't do Case statements like C or C++ and probably others do. I am trying to learn C on my own
But honestly I'm struggling with it right now.

Hi Andypugh . I have a Python question for you. From what I have read if you exclusively use "if" statements multiple one's can be true and
executed at the same time. if someone uses "if" and "elif" statements once one is true the rest are ignored. Am I understanding that correctly?
I am still very much learning this stuff so I don't know the rules yet.

An if and the elif statemts that follow it form a tree or line, that once one of the statements in that line are true, the ones that follow (in that line) are ignored. But that doesn't apply to other separate if lines in the program. They should still be processed individually. Elif (or else if) is kind of the opposite of then.

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

watch in action

  subprocess.call(strg5, shell=True)
