Z moves normally when the key is held down. Then runs on for an additional distance in the same direction. A 6.35mm move, moves the 6.35mm's, then drops to about .001mm velocity for an additional 9 thou at which point the pos-cmd and motor-pos-fb finally match. And its cumulative, ask it to move an inch (25.4mm's) at 500mm/min and it moves at that speed, then virtually stops, taking around a minute to arrive at matching counts, which can be an additional move of more than 20 thou at the end of the high speed move. So I have no instant control and that kills homing. The esc and f2 keys are ignored during this ultra slow final move. I'll do some more checking but that would be a lot easier to see if I could turn off geany's color as most of the vars and pin names are rendered in red. And thats making my cataract problems worse. Black text on a white screen is ok, red on white not so much. If I can find someone to drive me on Oct 17, I get the first eye fixed, 2 weeks later the other one.
