Hi,

My understanding is that Kernel Speed is not important when using a Smoothstepper as the step and direction pulses are generated by the Smoothstepper, not the controlling computer.

To answer your question, my Kernel Speed is set to 45000.  I use a 1.6GHz Centrino Dell Laptop.

Regards

Chris, thanks for your quick reply.

 I'm not using smooth stepper which is why I asked.

I just built this circuit, if you use low PMW, say 100hz, the spindle speed woobles, above 1000hz is a safe value. Thanks for sharing it.
