This is why I was asking if anyone has done this because I do not have the money to spend on parts I have built the entire engraver out of recycled materials. I do have some knowledge about electronics but when it comes to replacing parts with something that might be equivalent I dont want to be...
some people say you can use the lm1117 in a laser driver but i found a 903t63 on my dvd circuit board is that an acceptable replacement for the lm317 and lm1117?:thinking:
help would be greatly appreciated i an building a 2 axis laser engraver/cutter
