Custom M codes don't work on Rasberry Pi 5 + Messa 7i95

halcmd (and hal)  are fine with true/false for bit types:

pcw@pcw-HP-Compaq-Elite-8300-USDT:~/linuxcnc-dev/src/hal/components$ halcmd setp hm2_7i96s.0.ssr.00.out-00 true
pcw@pcw-HP-Compaq-Elite-8300-USDT:~/linuxcnc-dev/src/hal/components$ halcmd getp hm2_7i96s.0.ssr.00.out-00 TRUE

pi@raspberrypi5:~/linuxcnc/nc_files $ ./M101
bash: ./M101: cannot execute: required file not found

Likely means that bash was not found.



 

I thought the message was coming from bash.

The message is coming from bash (the current command line shell)
but I think the path in the script doesn't point to a bash executable.

That is, unless ./M101 works, it cannot work in LinuxCNC... 


 

The thing is that true/false has nothing to do with it. I tried 1/0, the result is the same. But I'll try the path to bash.

Actually I'd like to know why bash isn't /usr/bin/bash . As far as I'm aware all the build scripts for the image reference/usr/bin/bash and there was no issue when in the qemu environment.

Once again posting your code would help rather than fumbling around in the dark.

Friends, thank you all for your help. I solved the problem through digital outputs and remap.
Something like this -

O<auto_control_off> SUB
  M65 P0
O<auto_control_off> ENDSUB
M2
//

---

O<auto_control_on> SUB
 M64 P0
O<auto_control_on> ENDSUB
M2
//

---

[RS274NGC]
PARAMETER_FILE = linuxcnc.var
RS274NGC_STARTUP_CODE = G21 G40 G90 G94 G97 G64 P0.025

USER_M_PATH =/home/pi/linuxcnc/configs/GRINDER_CNC/macros
SUBROUTINE_PATH =/home/pi/linuxcnc/configs/GRINDER_CNC/macros


REMAP = M20 modalgroup=10 ngc=auto_control_on
REMAP = M21 modalgroup=10 ngc=auto_control_off

But another task appeared - to run scripts for turning off bits when pressing the "Stop" or "Emergency stop" button. It is necessary to stop additional equipment, as for example, the spindle and cooling stop.
