I been using my Duet board for my high speed FFF printer. It can be a bit heavy on the Y axis and I always had a problem with very specific move types missing steps. Today I think I found the answer, by initiating "jerk policy" to 1. I was able to stop a move that consistently causes a Y axis stepper skip. It always seemed to be a spot that went from a print move to a very short travel and print again.
I want to know more about what "jerk policy 1" is doing as the information that is readily available is a bit vague. From what I can gather some moves do not obey the jerk setting? I can't understand, or something is missing.
I am still testing to make sure its not some fluke, but either way I would like to know. Thank you!
