Strange non straight parallel lines while printing
Vcore4 500: I can't figure it out - why are those lines not straight. I can't feel any binding on both Y and X movements. If I make a smaller print it doesn't show up. Also I am not sure I see the same defect on the opposite diagonal.

And not sure why I didn't take into consideration your reply... It turns out it is over extrusion and lowering the extrusion factor this is issue is resolved... I should learn to read what it is actually written. Thank you for your reply.

Your nozzle is too close to the bed and you may also be over extruding.
i did extruder calibration - extruder was overextruding 1mm on 100mm. I also did z offset 0.05 up and it improved slightly, but the artefacts on the diagonal lines remained.
turned the print sheet and printed on the other side as well - few more diagonal lines without artefacts, but they persisted

notice how it started pretty good and the waviness started at 1/4 of the print
and there is somethin else that i find strange near the permieter/outer line there are no artifacts whatsoever - i will play with input shaping settings and/or print speed(will try lower speed)
