I have a curious issue with my Creality CV-30 Laser Falcon and files created with Lightburn.
Curves are not closed at the end but offset by up to 1 mm. The picture below is from a 20 mm wide engraving. See at the bottom of the left eye of the smiley and also a bit on the lower left of the mouth.
The gCode itself is correct. The end position is exactly the same as the start position.
The issue happens with any speed I set in Lightburn.
It also isn’t because of switching from G1 to G0 commands, it also happens when I replace the G0 with G1 so that the laser stays on all the time.
I would also rule out a mechanical issue since I checked, tightened and aligned everything at least twice. Also this is not my first laser, I’ve owned a dozen (hobby) laser machines already.
