Hi all I want to use pin 11 on uno for pwm and pin 13 for enable and disable laser, i got that right by recompiling grbl and uploading, it works great when i give a M03 S1000 command to turn on both pins but when i turn laser mode on $32 if i give command M03 S1000 only the enable pin13 turns on theres no volts on pin 13, ive read grbl laser mode, and G0 G1 G3 moves but dont realy understand it what command can i give to turn on laser pin 11 and 13? Thanks Mathys
It turns on during a move (for example G1 X100), see gnea/grbl for all the details of Laser mode If you just want to test, use the Laser On menu under Tool On in OpenBuildsCONTROL (software.openbuilds.com)
