When i first started my laser up i was getting alarm 11. Now the lazer will move frim front to back but not side to side. How do i correct this?

2 posts were split to a new topic: LightBurn - Repeated sudden stops after Big Sur 11.7.4 Update

I took a look for Alarm 11 on the GRBL docs.

Might you mean Error 11?

Please screenshot the error in the Console window.

Error 11 can be caused by incorrectly enabling ‘GCode Clustering’ in Machine Settings when the engraver is not prepared for the modified GCode.

You can check this in LightBurn by selecting Edit then Device Settings.
