hello group. Hoping that someone can help. I have blackbox and spindle working correctly however when I try to run a laser job the laser doesn't fire without the spindle . I've read all the documentation I can find on the subject. have remove the relay jumper, and tried a dbl throw switch on the on the 0-10v plug on the controller. Have no idea what I'm missing here
Grbl has only one PWM output (used for the 0-10v signal too), so control which one reacts by turning the spindle's power off if you want laser, and laser's power off if you want spindle
