Hi Craig
Just wondering if you have ever sent data (numbers, string, no digital/analogue inputs) from another software/interface (python/arduino) to Mach4?
My idea is to have an input signal that stops the gcode running, and then the "software/interface" decides the new gcode line where to start (another piece of data sent to Mach4), and then an input signal (string, or number) to start the cycle from that line.
I hope my idea is clear
kind regards
Pablo
