Hello Jeff, as I am very reluctant with systems I don't really know, I first connected Halscope to Axis (before changing anything you suggested in the files). I can see all three stepper pulse rows and notice that, for X and Y axes, they sometimes come in tight bundles (or packets) with lots of time in between, but usually are generated apparently at very irregular distances. Halscope trigger can't get a steady hold of it. I can't find a system in this pulse generation. I' using the arcspiral.ngc program where action runs mainly in the XY plane. At beginning and end of the program the Z axis moves up and down (alone) and, astonishingly, those Z pulses come very regularly and equidistant.
I am using this on a "giant machine" (with +/- 4m in each direction) I defined in order not to run into machine size errors with the example files. Some small steppers are connected, not being attached to a machine. The configuration of all three axes (stepconf) as far as speed, acceleration etc. is concerned is identical. I think this pulse behaviour explains the stepper rattling. What is the origin, and will changing the files as below (Base period, delete automatic reset, doublestep...) cure the case? Can vector interpolation of two axes be a problem, since a single axis move works regular?
