I built my 3D printer a couple of months ago, but I can’t get it to print sharp corners. The corners in the picture should be 90°, without any fillets:

During this test print, I played with multiple parameters: speed, temperature, acceleration, junction deviation, linear advance. All of these were also individually tuned previously. Nothing seems to make a difference.

Could this be a issue with the construction of my printer? I’m beginning to think my hotend isn’t rigid enough, but then I would at least expect better results at low speeds.

Edit: the printer is a CoreXY of my own design running Marlin 2.1.2.1. The Slicer is PrusaSlicer with most settings left as default (but increased speeds)

    It looks great. Ive seen some bad designs with weird belt paths, but not your case

      Tightening the belts seems to have helped, but I will have to do some more printing to be sure. Thanks for your help!
