My point is that it appears to choose the exact same values regardless of the timing info you give it in the timings screen. I find myself wondering what the point of the latency test is. But I admit I didn't do an exhaustive test for fear of killing my existing configs. >> Where are the step, space and direction-hold timings defined?

Unfortunately I have a noise issue on the encoder and limit switch lines. 2 sample intervals sometimes isn't enough to filter the glitches in the limit switches, but 3 intervals is too big for the encoder signal to avoid being filtered away..... I was hoping for a finer degree of control by using a shorter sample time. I know in principle I should be able to have two filters with different timebases, but I really couldn't get that to work. Perhaps I needed to try harder. -- atp ------------------------------------------------------------------------------ Come build with us!
