I'll take that :)

Unfortunately no. I would like to add a sensor but I need time for

I don't think that this will happen. Why borrow trouble from the
future? Address the problem if it happens.

Yep. Done that after LCNC told me the speed was too high.

Hi Andy and thanks for the quick reply
I don't understand why you feel the need to use the reset pin?

It seems that a
Hi guys, I hope you are all doing well.
Quick insight. I've made a router and the spindle drive I'm using has an UP
and DOWN mode for increasing and decreasing the working frequency. This
mode is not the ideal way to work with but I managed to set the frequency
with pretty good results. The mode
