How to resolve these Z layer lines ?
So iv had my U1 for a week or two and have started to print some larger objects.
However I'm always getting these layer lines starting at around the 55-60mm.
On multiple prints they show at the same location height wise, and it happens on all PLA types I have printed with.
Iv tried :
- XY belts tensioner
- Z belt tensioner
- manual bed leveling
- slowing down the print
Any suggestions would be amazing, although I think their may be something wrong with my right lead screw (however I'm having trouble convincing the original shop that it could be faulty)
Thanks in advance
