I currently have the MK2/4 board on my OX. The issue that I am having is while doing a profile cut with several passes, the final pass is slightly off which leaves a "ring" around the entire profile. All previous passes are perfectly flush other than the last pass. I have generated gcode with Makercam along with Vcarve pro and I get the same results. To me it seems it cant be the machine since all previous passes are in perfect alignment. I have attached a photo of the problem I am talking about. Not sure if anyone else has run into this issue. To me it seems its a software problem. I am quite the novice to cnc and Gcode so please bare with me.
