I use NEJE 2s max 80w. Cutting and lines work perfectly, but while engraving a photo or a fill, the laser goes over the edge of the object while being off, than goes back, so the duration is longer due to that. The extra distance it travels increases with speed, but the change of speed is not noticeable from about 6000mm/m plus. I assume it has something to do with the max speed and acceleration of both axes. I have tried to set it up to higher values, but it messed it up and it acted wierdly. Could you help me please?
