I think it’s time to ask for help.
I have a 50W CO2 (Chinese) laser cutter/engraver. It’s been few months now that when cutting SOMETIMES there are some “hiccups” on the step motors that cause straight or curved lines to shift (pictures bellow). What I don’t understand is that those backlashes are random because I’m cutting the same piece over and over.
I’m only cutting 1/4 birch plywood at 8-10mm/s at a power not greater than 20%, and a speed of 20mm/s at a power of 9-10% when engraving.
I already tried the following:
Adjust/loosen belts (all axis)
Clean tracks
Recalibration of mirrors
Reduce cutting speed
Reduce traveling
Different softwares: Lightburn and RDworks
Any suggestions?
Thanks in advance
