      I'm working on commissioning a new COREXY build. I'm getting the typical corner bulges on a 20mm calibration cube so I decided to try implementing pressure advance. The results were unexpected so I am wondering if I have a mechanical issue to work through?

      I printed two 100mm x 40mm x 400mm boxes with 2 wall layers. I use S3D which has no setting (that I could find) to set the Z seam to the middle of the wall so I cut a 0.01mm slot in the back wall on the model.

      I am perplexed by the layer shifting at the side with the Z seam. The top box was printed with 0.05 z-hop and the lower box without. The pressure advance settings are just copied and pasted from the Duet3D documentation page into S3D.
