What I note is that it is in the software and a universal specification. So it has to have some significance.

Allegro may have typoed, or something there. Because 200ns, well it is a lot faster than their spacing. There is something going on there that bears closer examination. But you were 1000 times off. Andy says it doesn't matter, and he may be right. But I can't see how it can hurt to change the number if he is right. This may be a case where no one is right though. Me, I'm keeping an open mind on the subject. I'll let you, and the motor have the final say for what is right.

Set it all at 2000ns and see how that works, then go up, or more likely down, from there. When you're happy I'm happy.

Hello again,
Well I have more of the machine setup, and am actually moving the machine, and drawing with a pen. So the problem I am facing is I am missing steps. If I run the test in stepconf for like a 50mm area, it will randomly lose a millimeter or so ever couple of passes, and eventually keep wandering. Adjusting the max speed/acceleration doesn't seem to help but it is hard to tell since when you slow it down, it is making less passes. I am running everything the same as above in the thread. What should the steps be in finding the source of this issue?
Thanks,
CP

Is it possible that it might be a mechanical problem? Mark any couplings or other mechanical joints to make sure they are not slipping.

How do maxvel and maxaccel compare to the actual maximums?

How random is the problem? It doesn't, for example, correlate to turning the microwave on? (or the spindle, or anything else electrically noisy).

Good point about checking the mechanicals. It is possible that the gear is slipping on the motors. I will mark them and try later.
