Correct, except encoder.nn.velocity is fed thru a last 4 edges averager to remove some of the noise in the encoders output. That unforch also affects the spindle to Z phaseing in the G33.1 backout. With a long peck cycle count, the threads get a bit schloppy. I may take that back out but the the gear backlash in the head gets noisy when fed straight thru. Very poor quality gears and bearings in the head of this mill. I need to take it apart and replace all the bearings with decently precise bearings. These ain't them. Roller skate stuff from vfx I suspect. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
