Posted · UM3 printing wierd lines and travels that cant be seen in preview

Hi, i have this wierd problem suddenly where my printer seems to make some wierd travels and printing extra lines that cant be seen in the g-code preview in Cura.

 

 

I've attached pictures which i hope explains the problem. I've circled a few of the "problem" lines that differ from the preview.

 

From what I can tell this is not stringing but the lines are being fully extruded and the extruder is making these wierd diagonal travels across the support-grid.

 

Material is Ultimaker PLA, black with settings straight from the NFC chip, i also tried silver, which has been printing perfectly until now. And i also tried slicing a different model with the same issue. I've also tried slicing in both Cura 5.0 and 4.13.1 with similar issues.

 

I recently did a factory reset of the printer and the issue arose after that.

 

Any insight would be much appreciated!
