there is one thing I noticed with probing velocity-fb from stepgen... When it
starts counting, it counts up as long as spindle runs, so it doesn't reach
certain number and stops counting up... and it also cunts up again after
spindle pause or stop.
Maybe I should try with spindle-ramp.maxv

So in my case I don't have any feedback from spindle or vfd (VFD has its own
