You might well be able to control it with serial. But PWM definitely works. > Right now I have Axis0, Axis1, and Axis2.

I have had a fiddle in a simulator. In the [TRAJ] Section of the INI you need AXES = 6 COORDINATES = X Z C. You then need to set up an [AXIS_5] Section with the parameters for your C axis. Set HOME_SEARCH_VELOCITY to zero, unless you want to set up homing to the encoder index (there isn't much point generally) In the HAL file clone one of the other axes (assuming that they are stepper) and connect to the axis.5.xxxxx pins instead of 0 or 2. That _should_ do it. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ EMC VNX: the world's simplest storage, starting under $10K The only unified storage solution that offers unified management Up to 160% more powerful than alternatives and 25% more efficient.
