Hello, I just got a Raycus 30w Laser cutter/engraver from China. I can't seem to get it to calibrate right on the EZCad software that it comes with, in order to engrave a small text onto a charm. The text comes out inverted, like a mirror image. Does anyone know where I can find how to calibrate it? Is it out of focus? Do I need to focus it? completely lost. Does anyone know where I can start looking? Thank you so much.
