I get very bad curves. Belts are tight. What else happens? Is this normal from the stepper motors or something i have to check?
Thanks in advance
If you rotate the art 90 degrees in LightBurn and resend the job does the behavior move?
There are a few things that can cause this.
Did you draw these using arc and circle drawing tools in LightBurn or are these files from a vendor.
The right leg of the mouse has a finer sawtooth shape than the pillow. This leads me to believe that it is not exclusively in the belt drive system or exclusively machine harmonics/vibration.
Short line segments may be starting and stopping the engraver, causing this behavior.
If you’re willing (and legally allowed) to share the LightBurn file, feel free to drag and drop it into the reply box to attach it and share it here.
If these are commercial files, you can send the file privately to me here for analysis.

Sorry for the delay. I lowered the speed to 12 mm/second and got much better results. It seems my Chinese laser cannot cut well with 20+ mm/second. It’s a pity to cut 4mm plywood at 12mm speed
