Centroid Acorn Plasma Users Manual Beta CNC12 v4.65 rev6
Electronic sweet spot
1.) Steps per rev set in the 1600 to 3200 range for stepper motors. Both the Acorn Wizard and the Stepper
drive should be set to at least 1600 steps per revolution. 2000 is a good steps per rev value to use.
2.) Stepper motors are required to have proper matching power supplies and AMP settings on the stepper
drive. Just because the motor works does not mean that it has been optimized for smoothness. No
amount of Centroid G code smoothing will overcome a stepper motor that has too many amps being
pumped into it or has its phases not wired properly for the voltage of the drive power supply being used.

motors instead of stepper motors
