First post here. I've had a Taig CNC for a couple years now, never got it working really well. Just started to work with it again hoping to get it running. Been following Mach since Mach1, using Mach3.
Running Mach on a 1.5ghz Pentium 4 machine, 640mb ram. The cpu has been overclocked from 1ghz to 1.5ghz. The Windows XP installation is not very old, though several programs have been installed and uninstalled, etc. If I have to, I suppose I could re-install it, again.
Here's the issue, I wrote a little program that goes
F10
G90
G1 X2 Y1 Z1
G1 X1 Y.5 Z.5
G1 X3 Y1.5 Z1.5
G1 X2 Y1 Z1
.....
G0 X0 Y0 Z0
I took a digital camera video so you could see the movement and hear the steppers. I sounds like they're losing steps, at 10 ipm. I did a FRO 10%, and it sounds the same at 1 ipm. I can see the motors stutter, all 3 axes do it. Mach3 is running at 25,000hz, it did it at 35,000hz too. Step pulse is 1, Dir pulse is 0.

Thanks,
