HELP - lines on the side of the print
Hi everyone!
I have bought Prusa MK2S printer KIT half year ago and it was printing excellent. Only had few minor issues like : filament grinding, material not sticking to bed... etc.
But now i have first MAJOR issue with it.
For no reason lines started to appear on the sides (walls) of the print (see attached image). Another strange thing is that it only happens on larger diameters. For example if would print a cone, lines will appear only on thicker part of the object, thinner part will be printed smooth.
Problem started from print to print (finished one print, started another right away) - not like printed would fall on the ground or someone accidentally hit it.
Doing research I found:
- Z wobble problem
- PID problem
...but I want to be sure what it is before I start big printer disassemble process.
Does this ever happen to you? Do you know what the issue might be and how to fix it?
Thanks!
Michal.
