It works. Out of curiosity I did the diagnosticts on my WORKING Crusader-M. It does everything it is supposed to. It eats uploaded code and makes the moves while turning on and off the spndle and coolant when needed. All tests pass except for the DUART, and now I'm wondering about the guys with balky Crusader-Ms and their DUART test failures. I'm thinking the DUART failure in diagnosticts might not have been the problem with their controls. Oh well, I've been slowly putting together a up to date control and when this one bites the dust I'll just swap it out. Maybe sooner if everything comes together finally.
