The high powered CO2 LASER I wanted to build for my first CNC machine just isn't panning out. I can't seem to make the necessary front surfaced mirrors with the equipment I have, and every time I try to buy a 10KW LASER commercially, they keep asking me what I intend to do with it! Can't imagine why... :-)
JUST KIDDING!
Seriously...my only real hangup at this stage is in building my own driver boards. I've got the chips, but my skill at circuit design leaves something to be desired. I've even intentionally limited the physical size of my design, so I don't have the 5' wide gantry problems in the previous messages...but the cheapskate in me wants to build my own boards.
Anyone care to help me out with the circuitry? I'm being quite serious in my request.
Allegro SLA7051M PWM unipolar translator / driver chips. I've only got 3 of them, so I need to get it right the first time!
