While cutting sometimes the AB Motors skip because of the high pressure applied on the lever.
Using nema 17 with 1A currently.
Did somebody noticed the same behaviour?

I wasn't able to solve this issue by now. i tried to reduce the cuttingmovespeed to a minimum but ist working for some cuts and suddenly it will skip. not reliable cutting over some swaps and longer prints possible by now.

so i had this issue too,
fixed it by doing a few different things

one i swapped out my 36-40 motors for some 42-40s
next i changed the run current to 1.0

if youre still skipping motors after that, its a set up issue and your plunger might be too long.
need to be very precise

fixed it by using a setting up a gcode, which turns up the motorcurrent during cutting and resets it to default afterwards
