300 rpms? This is plastic water pipe, don't want it to get hot. But I'll check G95 out as this isn't thread cutting. The docs say motion.spindle-speed-in must be connected. I thought it was but at 50 revs, a halmeter says 0.0000. What does it expect to be connected to? I've a filtered feed to the pyvcp tach, in rpms? Or does it need rps?, I have both available.
