General Mach Discussion / pci parallel trouble

« on: November 09, 2010, 09:51:10 AM »

I have installed a startech pci parallel card because there is none on the board.  When testing the port with mach3 i can jog any of my axis and see the volage drop from 5v to 0v, the problem is it stays at 0 until i reboot the computer.  Any thoughts would be greatly appreciated.

Thanks
