This is my first DIY CNC so I want to try to get it right the first time. Can anyone tell me if my stepper motors are any good for my project? (VEXTA E1.2-C19) I’m building a 42” x 42” aluminum frame CNC. I’m going to cut mostly wood but occasionally aluminum. I can’t find very much info on them. Also how does motor oz. play a part in the design? Thx.
