about $100 per axis here, assuming NEMA23 size https://www.omc-stepperonline.com/stepper-motor-driver/closed-loop-stepper-driver-0-70a-24-48vdc-for-nema-17-23-24-stepper-motor-cl57t.html
I have a 3NM NEM23 meter I'm going to install as the z axis on the mini mill with no spring or counterweight. If it does not work well I'l use a $100 per axis closed loop. I also have a 4" rotary table I want to motorize. Mine turns very freely and I can't see why I would need large motor. >> 2) The other option, more expensive is the now closed loop steer >> motors.
