Re: [CAD_CAM_EDM_DRO] Stepper Torque for a 7x18 Mill Drill (acme screws)?

400 oz in stepper motors driving the leadscrew with a 2/1 ratio timing
pulley should be fine.
I will soon have some stepper motors in the 500 oz in range that will be a
fantastic value. Watch my web page at www.seanet.com/~dmauch
