This one has me stumped. I have been experimenting with Mach3 on my Toshiba laptop with vista64 for about a week. Everything seems to function normally, but it has no parallel port and I didn't want to use smoothstepper. I bought a used Dell optiplex g280 on ebay to dedicate to cnc but it will not finish a run of code. I can look at the code in any editor and it is ok, but mach3 gets to somewhere in the neighborhood of line 150 and stops cold. The window where the code is displayed shows the line it stopped on and all lines after it being identical. If I take the very same file and run it on my laptop it completes without a problem. I first ran Win7 32bit on the Dell and when the problem showed up I loaded a clean XP sp3 32bit. It still does the same thing. Drivertest shows the system as being excellent with less than 2 us variation. The system is a 3ghz processor with 1 gig of ddr2 memory and a 80 gig sata drive. I can't begin to understand why it is so different between two computers with the very same file. files are created with Mastercam and I have tried every post possible and they all do the same, so I have to wonder about the Dell hardware. Has anyone else had any problem with Dell?
