I am facing the same problem knowing that my speed and power are more than this, I still can get the best setting to cut 3 mm plywood… I would like to ask you if you have faced a problem in engraving the shapes and words, cuz I have the same laser and whenever I start engraving or cutting something on the plywood it comes different and not accurate at all. Can you share me what steps have you followed in order to have this shape perfect as a line?
