Uneven Ninjaflex printing
With another MK3S, a kit I asssembled for someone, I could print Ninjaflex fine. With the printer I own myself, a pre-assembled MK3 upgraded to MK3S, preNinjaflex seems to extrude in an irregular way. When loading the filament, the Ninjaflex extrudes from faster to slower, depending on the position of the motor. Prints also have an irregular wobbly pattern.
What could be wrong? With both printers I've done a fair bit of Ninjaflex printing, so I wouldn't think it has to do with a clogged extruder gear or the extruder tension.

threadbump!
RE: fixed it!
Today I took the extruder apart to fix a few small things, and had a good look at the extruder gear setup. I couldn't find anything wrong, but I noticed again how the extruder gear was slightly at an angle. I've replaced it with a spare one, from my backup parts. And guess what... now it's working fine.
The printer came fully assembled, so it's from "something going wrong" or a production error...
