Hi everyone,
I've spent a few days on google searching informations about laser galvanometer engraver and i couldn't find too much about it.
I have a few electronics and cnc knowledge, but i cannot understand how this galvanometer is driven.
basically we have 2 motors which drive the 2 mirrors, let's say (x and y) but how you drive them? how they sync to draw a perfect circle for example?
here's an example of what i like to achieve:
