Sometimes when I print models octoprint doesn't print what the preview mode says. I preview the model in both cura and in the octoprint g-code viewer window, and both shows the model correct. But when I print some models, a round corner of a simple box has suddenly become straight because it has cut of the edge (so the model has become smaller. Other times, the brim or skirt on one or two sides of the model is not printed. Sliced in cura, designed in Fusion 360.
Changed version of Cura, updated octoprint to newest version, checked that bedsize is right.
