Yes, the print is terrible.
But I did just a quick reassembly with the new bearings to see if this got the trick done.
I should mention that the printer is a second-hand one so I can't say for sure if the parts are all original.
My last guess would be that the pulleys are wrong but I'd like to have a more educated guess from you guys.
I did print with standard cura (v.2.3.1) settings, normal quality pla. Other parts came out nicer in the past until the day I discovered the unround circles. Should I try new pulleys? Where can I get some reasonable priced within europe?
