Strange Vertical Lines on Flat Surfaces
Hello all!
I'm facing a weird issue of vertical lines showing up on smooth surfaces on printed parts. I noticed that this doesn't happen with complex shapes, but only on simple ones with somewhat flat surfaces. I'm not really sure what's causing this issue. Could it be a wrong Z calibration? Maybe it's setup too low and close to the print bed? I have 3 different MK3S printers and these lines are showing on all of them in somewhat the exact same places.
Best Answer by Peter M:
Has nothing to do with first layer.
Try different filament, en slower speed.
1 picture looks like linear advance
2 picture looks like seam.
Print a lot hotter, like 10 degrees, and test.
Nozzle partially clogged? Change nozzle then you now it within 10 minutes if this is the problem.

Those all appear (to me) to be your z-seam. You can minimize the appearance of the seam, but not eliminate it completely.
Thanks
Thank you guys @peter-m and @bobstro .. I didn't know about this. I'll try reducing the speed and increasing the temperature as suggested and see if this would improve the prints.
