I seem to be having a spot of bother with G76. I thought it was working fine, then noticed that the z axis was running at max-speed and cutting the wrong pitch. Slowing down the spindle and increasing the z-axis accel limit produced the issue shown here: http://www.youtube.com/watch?v=NDA48nLdbiI It seems almost like a badly tuned PID controller. It isn't a brilliant encoder, as can be seen on the velocity trace (but note that velocity baseline is at the bottom of the screen), but surely the position counts should update steadily enough? Which encoder position is meant to be wired to the motion.spindle-revs input, by the way? Stepconf uses encoder.0.position, but that seems to be an integer, and I am wondering if it should be encoder.position-interpolated. Watching the machine it is almost like it is updating the carriage position once per rev... -- atp -- atp ------------------------------------------------------------------------------ Come build with us!
