By playing with the setp values for the near (named close-enough) module, I now have its output, sent to spindle-at-speed, flicking on and and off, off for a short time after changing speed. This has similar inputs, currently scaled for 1st gear, rigged such that it should be true once the motor has assumed the speed commanded, so it wouldn't be sensitive to other than the load and slip angle that imply's. But, its sensitive to the gear change, so getting the proper scaling when the gear is changed is YTBD. Now, to go and observe it to see if I've still missed something. I think I have, but first a fresh printout so I can better track WTHeck I'm doing. This hal file, from the examples, that I started with was less than 150 LOC then, but is past 600 LOC now. The jogging additions are around half of it. I had no clue when I started out to make those work, that it was going to take that much hal code. But its working quite well with excellent repeatability. Another item I am fighting with is the following error, I've found that it must bet set higher than the backlash else it errors on the backlash moves, either axis. Should this be happening?
