Wtf is going on with my print and these weird diagonal ridges near corners.
Printer is the P1s. This only happens with orange nylon PA12. I've printed with a lot of different filaments like PLA, PETG, ABS, TPU, BLACK NYLON and a lot of PC and this is the first time it has happened.

I've tried printing with the default setting and also very slow, like 60mm/s 300mm/s^2, print speeds and it doesn't make a difference so it shouldn't be ghosting even though it happens near corners.

The ridges don't line up with the Z axis but at a 45° angle.

Again it doesn't seem to happen in any other scenario than orange nylon.
