I am little new here, but i have a problem i cannot solve. So i will try here to find a sollution.
A little background:
Using UM2 with Igus material iglidur® I150-PF. Making slide bushings for verious applications.
Settings : 0.4mm nozzle, 0.15mm layer height , 60mm/s print speed.
Extruder 245°C, Build plate 65°C
When printing there are 45° lines extra on the inner and sometimes on the outer shell.
It seems to be extra material and i tried a lot of different settings to remove it. Nothing seems to help. The weird thing is that a year ago i had no problems at all. So is there something changed in the default settings in Cura that can affect / produce this? See attached image for details of my problem.
The line seems to be random, but that is so far i can see.
Its is the Z-hop? Retraction?
Please help, would be i big help if somebody can help me solved this challenge.
