Mach3
VcarvePro 8.5
Candcnc control boards

I recently connected up my Hatachi router on my CNC to the router relay on the Candcnc control board.
It is energized by M03 in the gcode it has worked flawlessly for about a week, however today it didn’t energize.

This happened after I had edited the TXT file in Mach3 changing the feed speeds, I verified that the M03 bode was still in the TXT file where it should be. I canceled the file and reran it several times but the relay wouldn’t energize.

I shut Mach3 down and restarted it and running the same file the relay energized properly, I canceled the run and started the code several times and the relay continued to energized properly.

Not sure what caused the relay not to recognize the M03 code, now I am unsure of the machine.

Any ideas as to why the M03 code wasn’t being recognized?

Thanks
