Trapezoidal spindle Upgrade

Hello

I just got my trapezoidal spindle installed but my Z axis is traveling very fast and too high.
I changed the code to:

#define DEFAULT_AXIS_STEPS_PER_UNIT   {64.25,64.25,4266.67,600}  // default steps per unit for ultimaker

I changed this 64.25,64.25,[color=#FFFF00]4266.67[/color],600}
But it still travels too fast.
Do I need to change more or have I done something wrong?

I think 4266.67 is 2X the number that you want. If you are using the stock Z axis stepper motor and stepper driver card, you should be using 2133.333 instead.

Hope this helps!
