The computer of my CNC died and I replaced it with a Dell Optiplex GX270 Pentiun4 and Win XP, after connect the parallel port, my problems began. Unexpectedly, the engines stops, making sound. This occurs unexpectedly in any of the 4 axes and turning the system in very unstable.
The Test Driver tells me excellent control system, with max variations of 20 ms. I have also made all the recommendations of "Win XP Optimization", without results. I also tested another PCI parallel card, change step pulse and dir pulse etc,etc,etc...
Any idea or solution recommendation.
Thanks,
German
