New R2 - getting bad prints.. Why? :)

Hey guys!
I bought my R2 a while ago - and haven't had time to set it up until now..
But im getting crappy prints for some reason. Nothing works really It starts out fine and then goes bad.
See attached pictures. What am i doing wrong ?
Out of the box R2 using Cura. Tried different fillaments aswell. Same issue!

 

That almost looks like the same issue I had when the extruder was’t moving filament reliably.
If you take off the cover on the top of the extruder (after heating the hot end up and removing the filament), you will see a plate with a Phillips screw. That plastic plate covers the area where the tensioner that holds the filament tight against the geared rotator is. If you remove that plate, you can use the included Allen wrench to tighten the tensioner. In my case, it had become so loose that as the print was in the middle of printing, it would separate like yours did (under extrusion). You can also make sure that the filament is being moved by the geared drive, and that it is not all gummed up with filament particles.


Sorry, I am not near the machine at the moment or I would have taken a photo for you

The screw is this one

Take that screw off, and remove that small cover. Then behind it is the tensioner I was mentioning. There are several posts on this forum about it, so that may be why no one has written you yet.

I would also check the diameter of your filament. I recently had similar issues due to the filament being slightly larger than 1.75

I actually just went through similar issue, for me I think the filament was the main issue mostly damage from humidity and cold weather. I tried it with used but sealed filament and worked just fine.
