pin 'hm2_7i95.0.ssr.00.out-01' is connected to a signal

Is the error, you cannot change the state of a pin that's already drive by a signal in hal
You would need to delete (or comment out) the net command that connects
hm2_7i95.0.ssr.00.out-01 to a signal in your hal file for the MXXX script to work.

Thx for you pointing this out and your hint on 5V relay.
I do have a parport based router. All pins are used, and still I want my vacuum clamping, dust extraction, myst (maybe) etc. to be operable from within axis (in my case).

Tried it two ways, still doesn't work. In the first case it gives an error.

pi@raspberrypi5:~/linuxcnc/nc_files $ ./M101
bash: ./M101: cannot execute: required file not found
pi@raspberrypi5:~/linuxcnc/nc_files $ bash M101
<commandline>:0: pin 'hm2_7i95.0.ssr.00.out-01' is connected to a signal
: numeric argument required

Does the script work if run from the command line?

 That is, does:

./M101

work?
 

Does the command you are trying to use in the M-code, work in a terminal from the command line?

Do you get any error messages in the terminal when you try to run the M-code if you start Linuxcnc from the command line?

Sounds like it should be a straight forward analog system conversion. What about things like the spindle controls, does it have a tool changer?

Best advice, is first thing e-stop circuits, then get encoder feedback working, then the servo drive enable\disable, then add safeties (limits etc), then confirm directions are correct, finally tune your position loops.
