I have a ls3040 (rabbit 3040)
After a job engraving acrylic which lasted about 10 minutes I have now found that when cutting anything lines are not straight. There is a small kink in each line and lettering has a kink along each edge. Circles don't join without a kink in the line.
I am assuming this is a mechanical problem rather than software as I have tried two computers and haven't changed any software settings. I am more confident with electronics than mechanics so don't want to start experimenting with adjustments without advice.
I am not sure what needs adjusting, if anything, and would appreciate some ideas as to what might be causing the problems.
