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?
here's an example of what i like to achieve:

I will never not think galvanometers are amazing.

To be perfectly honest, you may be better off asking this question at photonlexicon.com
That forum is full of people who work with laser projectors, of which galvos are proprietary. They will be able to answer any questions you have :)
