im too looking for this option

Tonybeta01 commented 2 years ago

Can I use M42 to change a pin condition? also can I read a pin?

Tonybeta01 commented 2 years ago

as per this: https://marlinfw.org/docs/gcode/M042.html

is there a quick and easy way to find out which pins are free?

Saur0o0n commented 2 years ago

This should be easy enough :)

Tonybeta01 commented 2 years ago

so M42 is not supported , thats a shame
