You will need to give more info,
what pitch screws?
What stepping are the drives?
Any gearing between motors and screws?
Metric or Imperial setup?

Do the drives have any multi stepping or micro stepping? If you are not sure then what make?

Pitch screw = 2mm
Bipolar 200 step motor
Gear ratio = 2:1 (screw gear : motor gear)
Metric

In full step mode:  200 * 2 / 2 = 200 steps/mm
In 1/2 step:  400 steps/mm
In 1/4 step: 800 steps/mm
In 1/8 step: 1600 steps/mm

Make sure you do not have a printer driver installed.

If your mouse is compatible enough (most are) you can remove any special mouse drivers that came with the mouse, and it will still fuction, albeit perhaps without whatever 'special features' it might have had.

If you are getting some kind of unthrottled poling of the parallel port or the mouse port which is disrupting Mach, then unistalling the drivers might clear up the problem.

I don't have any printer install or any other drivers except via4in1.
It's xp+sp3 + updates - fresh installed last night. After reboot it work fine for about 8-10 seconds, and then loose step, anoying comportament of the motor (when I move the mouse, the motors take speed).
should I uninstall sp3 ?
I don't find in bios any ACPI (enable/disable), I have disabled Com ports, Paralel port change to ECP, load fail safe bios defaults, without any luck !
What drivers should I uninstall ?
