That would be about 500rpm to run 100ipm. 400rpm to run 80ipm. The machine gantry would weight out about 250lbs with dual y drives supported with sbr25 rails. That should be way enough power to travel. The force will be a spindle motor not yet selected for cutting hardwood/alumnium at times. Process time isn't important to me. My question is can i run direct drive to the ball screw? Or would I be disappointed and wasting my time?
My other option is using 10mm pitch ball screws with a 5:1 gearbox. That would be max 196ipm. @ a more than double the cost.
