You are going to need have some electronics knowledge if you dont use a pre-made driver.... asking if a 3.3v regulator can be used as a driver suggests you might not.

Buy a driver, you will save money.

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 wrong and it blow up on me cause i may misread one thing. So I thought I might ask someone with more knowledge than me. This is not my first project I have made many others. So if someone could please help that would be great.

sorry im not trying to be rude if i am
