Huh? My docs say it is. See 5.1.4 at the top og page 184.

No I think we are on the same page, or quite close. Thanks Marcus. Its a pita having both milling machines laid up, and I'm having to buy another just to fix the first blowup right, while adding more I/O it needs. I keep hanging more gingerbread on it. Then a $3 buck regulator up chucked and put 35 volts on a bob, cooking it, black epoxy bits all over. So this is the back panel of a new box with 11 round holes and 2 dsub-25's in it. But theres AC in (1), 4 motor outs (5), an encoder in(6), a gear shift tally in which may use its spare pins for the probe(7), soon to be independent home switch ins(plug-8) for the 3 main axis's, and at some point a tool changer, which will have to sequence several things that will eat up the last 3 of those 5 pin GS16-5 connectors. Then to make things interesting, this incoming 6040 gantry expects Mach3 on the db25 end of the cable, so there may be a bit of hacking there. I'm passably good at that, as long as I've got the docs for everything. Thanks Marcus. And Merry Christmas.
