I get the machine running last week, everything work fine for the tube, beam and focus.
I am able to engrave Granite and Glass, my goal...
Still need to figure out how to print a (black and white) picture,
If someone know how to drive the power supply via PWM I will take the advive
OK my question is:
The focus lens I have came from here and it is 55mm.
For a cutting application I think a 110mm would be better, and cut deeper because I will get
a very thin point(I mean on the part) So were I can get one?
