but there was no answer to the problem.
OmTech GR10MAX. New machine bought on December 2022.
Belts tensioned correctly (no grinding shifts)
Layer settings - high speed, idle speed and accelerations checked both slow and fast.
Shifting happens only when changing layers and not always only in this one part (cant include rd file in here, dunno why) The shift happens when changing from Ekwador to Brasil. That problem occurs spontaneously but when it does it is always this part of map and at this angle. Already tried to do it slower by 50% but it didn’t help. Tried all of ideas from topic attached. Changing USB Port, cable, etc. Please help if you can
