First post, 4' X 4' cut size
Hoping for some advise, with my plasma table ,i have looking at keling cnc packages 495 oz in 36v nema 23 ,I called them they could not tell me the torq curve for the motor wouldn,t that be the target RPM for gearing? I have also heard that running the motor to fast will lead to in accurate steps ,the other way the motor is sluggish They did say that speed is not HP . I would think that a table that runs a router would need to have alot more power than a plasma torch? I have the base built with a water cavity under the grids.I am leaning to rack and pinion on X and Y my x having a common shaft and drive both sides at once using 1 motor . Direct drive Z with a ball screw 12".My "Bridge" as i call it made from all aluminum .I also intend to use mach 3 if that matters.Any thoughts on the matter would be GREAT !!
