I have a small niggle with my newly built machine. The PC is built into the machine housing itself so it's a complete unit. When I press the PC on button the BOB is closing the spindle relay, making the spindle spin until I enter EMC2.

Is there anyway that a PCI card can be configured so at not to send out a signal during the boot sequence? I thought about inverting the relay contacts & BOB output, but that would make the spindle start as soon as I plug the machine into the wall. I know I could rewire the spindle to take power from the seperately switched motor drives but i was wanting to keep each system individually fused.

Many thanks,

Gavin
