Laser burning lines while traveling


(Jeremy Curtis) #1

Hello all, I had my laser/software for about 2 months with a handful of projects under my belt. Yesterday was the first time I saw the lines from the laser as it traveled. It only happens during short travels. Any ideas on what could cause this?

You likely don’t have laser mode enabled in GRBL ($32=1), which would make the spindle PWM output ramp slowly instead of instantly, among other things. The spindle PWM output is used to set the laser power.
