do you ever plan on CNCing your mill? if not thats ok! it would probably be something you could put on your resume, seeing that you have a mechatronics major! if you did, you would have to replace your acme leadscrews(spindles?) with ballscrews.
do you think that a 0.12kW motor will be powerfull enough? what will you be cutting?
