There was a trace at the top of the screen that looked like a sawtooth, and had "error" in the signal name. What was that? (I couldn't quite read it on the photo.) The only thing that could cause such a perfect sawtooth is a full-scale oscillation in some loop, causing its output to be a square wave. I'm wondering that it must be caused when the Z tries to sync up to the spindle, and exceeds the axis' velocity limit. Once it gets behind, it then suffers from some integral windup kind of problem, and keeps overshooting the required velocity. I am assuming all this from that sawtooth.
I don't know the new stepgen at all, I deal only with servo systems, here, so my expertise is quite limited.
