Strange vertical lines on X-axis direction of parts This one is turning out to be a real head-scratcher. I'm running a stock Creality CR-10S and there seems to be a single line approx 45° across the print on the X-axis direction.
I have attached images to better explain. Any help would be greatly appreciated.
In your slicer check your z-seam overlap. Lines like that are what happens when a slicer is systematically trying to hide a seam while not adding a ton of time onto the print by adding in a bunch of additional time for travel.
