I think I hit a good lick today, still using the chipped 1/32" bit, I modded the code to only dig about 25 thou, and mounted a 3" piece of .0155" thick alu I'd kept from the change door color inserts in the last failed dishwasher. The bad mill threw up a ledge, particularly when cutting the big circles, but I was able to trim those on a sharp file and one of smiths hard arkansas stones. Blew it clean after all that, and installed it. My analog scope says thats the best set of quadrature A/B pulses it has looked at. Encoder_velocity output noise is about 1/2 what it was before.
The hal scope however says the duration of the pulses is jumping back and forth according to the time quantization of the 26 u-sec base-thread, and this is the major source of noise in the velocity feedback now. So a 5i25 is the only way to fix that. What do I have to change in my hal file to cause it to load the correct hm2 files? And, how do I modify the pinouts going to/from the parport, so they come out on the same db25 pin I'll move my BOB to?
