Laptops are not really supported as there are issues with other pc functions interferring with the operation of Mach.
They can be used with an external motion device.
That goes for a laptop using a docking station. Dell's can be problematic as the signal output to the PP is not clean.
I assume you were meaning 25000 in the dirver test , if , truely 2500, then forget that pc.. So you have one of the famous TB
Chinese controllers that frankly i will not even remark about other than "good luck".
So in general reply to your question...........yes ...know problems.
Oh BTW, don't play with your mouse as that "may" create interference. You can see it in the driver test.
