I solved with 32=1 …

I get the honor of saying this “fix” has nothing to do with your reported alarm message. Error20 is almost always not bad Gcode, but a USB communication problem instead.

This is intriguing but possible. If Sculpfun removed the GCode functionality for Spindle Keep-Alive ($32=0) it could throw Error 20.

Maybe they got tired of answering $32 questions. :slight_smile:

Button said start topic, so you get my reply this way. :grinning:

I have the S30 Pro (Max is 20w vs my 10w) and it was shipped with $32=0. Never saw an Alarm 20. I did Frame then Start a couple of times before I spotted the result of laser staying on.
