to get a fast feedrate should i use a G0,

G53 G0z-32.00

or use a feedrate value

G53 Z-32 F1000

Got an odd one here, i need to move the z axis to -32 relative to the machine coords regardless of what offsets are in force. It's going in a toolchange macro to set the z height for the toolchange. Is there a G code to do this.?

I try to use pentium 4 pc's and have very little trouble with them, whether they have dedicated graphics or shared graphics cards.

The most important thing to remember is the computer is there to run a cnc machine, and only a cnc machine, no frills or internet or virus protectors or ultrasonic keyboards or mice,  or anything else.

Keep it simple and it will work.

I have used just about every make of computer out there to run mach 3, and i see more problems with the compact desktops than any other type of computer. One advent compact desktop did have a similar problem to your computer, poor running, grumbling drives, in the end i binned it. You could try a seperate ground from the machines drive electronics to the breakout board, it has helped in the past.
