Hi everyone,

I'm designing a 2'x4' cnc router with a 3 kw air-cooled spindle and 15mm ballscrews, but i'm running into an issue. Servos are well out of my price range, so I was looking at close loop steppers like this one: NEMA 23 Closed Loop Stepper Motor System-Hybrid Servo Kit, 32 bit DSP Based | Automation Technology Inc. My only concern is that the stepper is only has 282 oz-in. of torque and i'm not sure if that's enough for this table size. The open loop stepper I was looking at was 570 oz-in. or torque.

Any suggestions?
