Centroid Acorn Plasma Users Manual Beta CNC12 v4.65 rev6
Clearpath Axis Motors.
Teknic Clearpath motors provide fast smooth powerful motion work well with the Acorn CNC controller and
are a good choice for a plasma machine. There are two main models of the Clearpath stepper killer
motors. A common Clearpath purchase for a plasma machine is the lower resolution less expensive
clearpath model which runs at a native 800 steps per revolution. If you can spring for a few more bucks we
highly recommend purchasing the higher resolution model which provides 6400 steps per revolution.
Clearpath has its own smoothing algorithm (called RAS) built into the motor drive firmware. This works
very well for XY motion but for the Z (THC axis) this feature must be disabled.
In the Clearpath MSP software on the Z axis motor setup like shown below.
