I've got that combo and can cut at up to 20ipm, and rapids up to 30ipm using direct drive. Dont gear your steppers to the leadscrews. You would think that by gearing one 2:1, it would increase torque 2fold, but it really woudn't. Steppers loose more torque the faster they rev, so you would cut your ipm in half, and not even get 2x the torque. Do a direct drive. IE, use a coupler from leadscrew to stepper motor. |
