Laptops are notorious for having issues with the driver and that is why Artsoft does not recommend or support their use unless you plan to use an external controller such as the SmoothStepper, DSPMC, Galil etc.

The more stable / consistant the pps and closer to kernel speed is during the driver test the better. Wide swings like you are talking about says that particular pc will problematic. Example, my PC will consistantly be within 10 of the kernal speed and only varies by 1 or 2.

Ok you have sherline mode enabled, that means you can not set the pulse width as it is automatically set in that mode to achieve the widest ulse possible at 25KHz.

ok i turn off sherline mode and is the same nothing change
-
So your problem is you can not set puse width to 2 or 4?
I tried with your xml and its fine, in fact it was actually set to 2 fr pulse width a Dir was zero.
