this is a cory XY with a Kracken head, 4 nozzles 4 extruders
All x/y/z/ movements are fine and at normal speed, but fore some reason the extruder will slow down to barely visible movement. stepper and wiring have been verified and known good.
a power cycle fixes the issue for a bit and then at random it slows down.
