@unixb0y Know what could be the cause for this rough surface [i.imgur.com] when 3D printing? Seem to only come when the nozzel (moving anticlockwise from middle.) is moving left and up.

@runeranch only seeing the image I would say maybe the bed isn’t perfectly level and higher in the back, lower in the front. I haven’t encountered such artifacts in relation to certain movements yet though.

@unixb0y Asked around. Many seems to think it is the x belt tension and or angel of that belt.

@runeranch okay :) since you mentioned it, maybe a shot from the front of the printer

@unixb0y CR-10S front [i.imgur.com] and closeup of extruder [i.imgur.com] . I have adjusted the X belt tension and angel a little.

@runeranch can you actually change the X-Axis angle on the CR-10? Now I remeber that it only has one Z-Axis motor right?

@unixb0y Two X-axis motors. What I did and helped so far is: adjust X-axis belt tension and the belt angel. The teeth of the belt was scraping underneath. Also my nuzzle was crud / not flat. Sanded it a bit and my top layer has improved a lot.

@runeranch hmm... definitely everything looks fine in the pictures. Weird thing with the nozzle, I never had that. Maybe it was a bad quality part :/
