i want to add custom Machine code to set a pin high or low, is there any info on how to do this ?

@sinfocomp: I am wondering this as well. I have been trying to find any gcode interpreter which allows custom m-code creation in order to turn on or set output pins. Have you found any version of GRBL or otherwise which allows this?

if it is possible to add a new M command, I must look as I have done, you must add lines in two files. I implemented it for a project that I hope will soon come to light (it takes more than 9 months)

I'm interested in this too!
