That will teach me the syntax. Back to pinouts, I got mesaflash to read it, and I find that what I have wired at the BOB up is amazingly close. If I can disable stepgens 4-7, and move the encoder feedback by one pin down on Phase A, 12 to 11, and Phase B from pin 15 to 12, that should take care of the encoder. The motors run, but backwards, slow (99mm/minute) and call a surveyor for accels. I suspect because I set mm in this, but the ini is in inches for those vars. And they stop (no errors reported) for what should be a continuous jog after 3 or 5 seconds, needing a release and fresh push on the arrow keys. I need to hit pin 17 with a spindle enable, lack of that keeps the spindle quiet atm. So obviously that needs to be an inverted out, this BOB doesn't take an in on pin 17. Getting rid of the last 2 stepgens on P3, gives me enough pins to do the rest in hal (I think) I've no idea how pwm knows a reverse, (look at the hal) what I do in hal is 100% fwd via some abs modules, and the reverse is done entirely in relays as its a single quadrant driver. IT cannot go straight from fwd to reverse, so I have to manufacture a stop when the fwd/rev line changes state. Part of the reason my hal file is very close to 300 LOC. If the pwm "dir" on pin 16 can be free'd up, leaving that pin for my hal to handle, then my hal's chicken waving can do it in the proper sequence to make the G33.1 work. Home & probe are input on pin 10 inverted, currently free. Some limited progress at understanding, no edits have been made, yet. Thanks for your patience Peter.
