It has been a little while since we worked on the engraver. The last time we worked on it I had just gotten the pci parallel port installed and working when the computer crashed hard. So I called it quits that day. I had been unsure of the proper configuration of the parallel port address and so had chosen a number that appeared in one of the tutorials. I now know that this was the wrong number and caused a major fault. Today, after doing some more searching I was sure I had the right address, but still couldn't get any commands out the pci parallel port. Everything I tried resulted in nothing happening, no faults, no error messages and no voltage change. Finally the ME suggested I try a different pci port. Bingo! that was it. It turns out that this is the same computer I burnt up a NI-6025E card in, apparently it also took out part of the pci bus. Now all the axis jog and I even started a part program without trouble. Next time we will tune the steppers and get the home switches working.
