The only point that makes me question the boards fitness is the apparent failure of the x channel on the board. That is the skipping started on the x axis board port and got worse, I changed the from the TMC5160 to DRV8825 driver and that made no difference in the skipping, so it’s not the drivers. However when I changed the pin assignment to move the X axis to the E2 board port that seemed to fix the issue…for the moment. I’m willing to concede that the skips in the above print may not be a board issue but the symptoms are similar if not the same. The only way to really test is to swap back in the Rumba32 board and see if the issue persists.
