I was doing a score operation on cardboard with speed relatively high and power of about 4. The operation worked fine but when doing small letters, specifically a letter “c” which appeared 9 times in the design, the motion got very jittery almost like there was a resonance in the commands sent by the stepper motor and the gantry itself. The noise made by the laser head moving around also didn’t sound normal. Sounded almost like the head was hitting an obstacle.
It didn’t seem to affect the accuracy of the scores, but the motion and noise was kind of alarming. I tried to take a video but it’s not really that visible in the video. Maybe need to try a lower speed for this sort of fine detail?
