Hi
I have a setup that is running on a cheap usb mach3 controller on 3 axis for a tablesaw, using this kind of controller:

I have an issue with on of the axis, the more moves it makes, the more it drifts off positioning. so after approx 20 moves, with same start and end pos hitting a dial indicator, it has drifted off approx 0.7mm
This is a card labeled 100khz so in theory it should be able to pump out enough pulses.
But I thought I would try another board, and got the ethernet version of the XHC-Motion cars MK3:

This is a 2Mhz card, so it should be able to shuffle out enough pulses.
However, this seems to be even worse.
I cannot get consistent positioning trying to run the same axis as the one I drove on the usb version.
Does anyone have any experience with this controller?
It comes with a designated driver for Mach3, but this mainly has settings for I/O´s, and no motor tuning settings.
