As Bas says they are not suitable for spindle motors, unless you have
some sort of hybrid spindle requirement
that involves positional placement (indexing etc.)
You can use the step generator to drive a 'speed board' which controls a
spindle.
Set the stepgen to velocity mode and the speed board converts the step
frequency into an analogue
signal to drive the VFD or similar.

Hello
Has anyone tried setting up stepper motor as spindle with machinekit. Maybe you
have some example configs or examples.
Thanks for help.
My guess is that a stepper motor is not suitable for a spindle. Mostly because
speed is limited wrt other motor types.
Apart from that, if you set the stepper up in velocity mode instead of position
mode, then that should work.
There are beaglebone configs in the repo which show how to set stepgens in
velocity mode.
