    Don't set the Kernal speed higher than 25Khz if it does everything you want which it will with just 24V. The Kernal speed isn't directly related to how fast your PC is but more how good your parallel port is. I've seen some high spec PC's that just can't touch some much lower spec PC's because they have fast clean pulses coming from the Parallel port.
    The further away from 25Khz you set the Kernal the more chance you will have for trouble.!

    Ahhh that's interesting, thanks for clearing that up!

    If you want to test how good your parallel port is then run the Driver test in Mach3 folder.! . . . Look for file called Driver test.!! . . . This will show better if your PP is up to speed.?

    Just another thought about pins :- the enable pins for the axes might be better set high, even though the TB6560 has internal pull-up resistors, a floating pin could cause problems. X=4, Y-17 and Z = 5.

    Yeah, found the driver test when I was trying to get it to work when I was trying on windows 8, Will try it on 7 when I get home, thanks for your suggestion! I will also try those enable pin settings.
