    Still haven't checked the video card, but managed to run a few more quick checks last night. Attached is a photo of the oscilloscope display when connected to the parallel port lead, pin 3 (x steps) during trraverse. First photo shows scope with even spaced pulses, second photo shows the glitching of uneven spaced pulses.

    I'm also have a video of the steppers running. I will post later, and you can hear the glitching.

    Screen shot of DriverTest program, shows all is well.

    Also switched off Virus checker, and set it up to trust Mach3. Made no difference.Click image for larger version.  Name: diagnostics2.JPG  Views: 2106  Size: 313.1 KB  ID: 2208Click image for larger version.  Name: DriverTest.JPG  Views: 1149  Size: 58.5 KB  ID: 2209
