I think you guys are thinking of this exactly backwards. If I understand right, you want to move the table manually while the spindle is running. You've gone down the path of wanting to trick linuxcnc into being in "machine on" mode even though the amps are disabled, so you can tell it to turn on the spindle. But the better solution is to leave linuxcnc in "machine off" mode, which disables the amps and gives you a working DRO, and more importantly, the position tracks so when you go back to "machine on" you don't get a nasty position jump or any other weirdness. So the problem remaining is that linuxcnc won't turn on the spindle in this mode. Right, so poke the button on the VFD that makes it come on, or install a (real actual) switch.
