I have been working on a robot project for a while. Now I am tired of finding parts that just does the job, so it is time to do create parts.
A 3D printer will do the trick for many parts, but 3D printers share a lot with a CNC mill in terms of control and parts. So my question is this:
I am building a Reprap style printer, but I will use more heavy duty parts and motors, hoping to make a aluminum capable 3 axis mill later. I found some bipolar NEMA 23 stepper motors at 1.9 Nm and 3 Amps per coil. According to the reprap.org website, they recommend NEMA 17 and low voltage. Seems to me that they use voltage to limit the current.
Can I build a reprap, and use current limiting stepper drivers with an Arduino and some software I find online, and get away with these large stepper motors? Or am I in for a lot of trouble?
