Bill, A 387 oz nema-23 has 24lbs/in of torque. What are your thoughts on how strong it needs to be? This goes back to my earlier question about proper sizing. I don't think I've ever applied that much force when turning on my LOM but then again many folks may have used their machine in a different capacity.
Dustin, How much did your setup set you back (if you don't mind me asking)? I noticed that you are using Mach3. You've essentially turned your LOM into a CNC Lathe and small bed CNC. What would you do differently in retrospect?
