I have to drill/tap three holes in the face of a part, cut-off and transfer to the subspindle, and drill/tap three holes in the back side of the part. I have to have both spindle oriented for the transfer, so here's what i have tryed.
I turn the front, stop main chuck, orient to zero, orient subspindle to zero, clamp subspindle, and try to turn both on simultaneously. As the part is turning, you can see it leaving marks from slipping in the subspindle.
M110 (clamp subspindle onto part)
G04 P2. (Dwell)
M04 S100 G04 P2. (Main spindle on, dwell)
M143 P100 (subspindle on)
Thanks, anyone who can help.
