To reduce the suspense, its working. Milliseconds response to turn it on, and about 2/3rds of a second to turn it off. Thats more than good enough for the girls I go with. ;-) But my other comment re achieving independent control from gcode still stands. I do have independent control from mousing the axis check boxes, but in gcode, an M9 turns them both off. Not an ideal thing IMO. I'll go read up on remapping & see if I can get my head around it.
