There's a huge SuperPID thread at CNC Zone with help from the designer.

Do you have a V1 or V2?
On Ports and Pins, Spindle TAB, do you have "Use Spindle Motor Output" and "PWM Spindle" checked? Do you have a pin setup on Motor Outputs for the spinde Step pin, which is used for the PWM?

What works perfectly?

You can only calibrate the spindle if you have the tach input connected to Mach3. And it's not recommended to do that with the Super-PID, as it's not needed.

Try deleting the file linearity.dat in your Mach3\macros\yourprofile\ folder, then restart Mach3 and see if it helps.

If not, post your .xml file. You either have a Mach3 setup issue, or possibly a wiring or parallel port problem.
