Woah. I didn't think I printed that much : 430h. By setting it at 230C I haven't got one problem in 20h of printing, so that's nice. Still two points from your list I haven't tried that could be the problem too, gonna get on it.

No I don't have a way to measure the temp but since it worked great at the beginning on 210 and now I have to set it at 230, I thought it was the temp sensor that was off. At least something change that maybe could been fix if I send it to repair (also the leds are hanging :/). What do you think ?

Oh thanks I was doing it every time I print in "Tune". For me it's off by 20C because it's where I get the best print. Can this be fixed by the warranty ? Anyway, thanks for your answers guys, really helped.

230°C. My temperature sensor miscalculate of 20°c then, nothing I can do except change it ? It's going to be a pain to change it everytime I print something.

A bit at the end but not much, it was hanging around between the two pulleys; not really affecting anything, the glue was wearing off I guess or the leds were burning too hot.

Thanks for your answer, I'm back with a bunch more result... not great. The last photo the feeder pressure is at 50%, everything OK until the last hour where it does something I don't get, do you recognize any pattern to know why it's happening ? 12 hours for that :/ Thanks for your support though

@gr5 On some places it's like 90% transparent and other parts are opaque I start my long print after fixing bed level, first layers looking alright After an hour What's going on with my UM2+ ? :angry:

I will reset the level then and see. I use the latest Cura version at normal settings. The only thing I changed is 0.2 in layer height.

Tada, so I went to make some of my prints I wanted to do but couldn't because of the issue. This is what I get for the beginning and I don't want to launch a 5h+ print for nothing. What do you think the problem here is ? At first I thought it was the bed adjustment that were wrong but it seems partially good on top left and good right side...

Ha ! I guess in theory it makes sense. Just leaving the thread open/best answer in case the issue appears again magically, making sure. Thanks guys.

What kind of sorcery is this... The prints appears good now. So it's grinding when there is too much or not enough pressure ? How to know the difference ? Thank you !

Yes I tried multiple brand of filament, same thing. I don't understand the thing about yop and middle ? Do you mean pushing to this line ?

It's just eat through the filament if I make it lower and stop feeding though

Hi SandervG, I have an UM2+. The feeder had always this problem from the beginning, I have cleaned it, changed the tension to the minimum, it's a bit better but clearly how can the minimum tension give so much grinding ? Tension feeder Top view coupler removed Face view coupler removed Coupler view 1 Coupler view 2 Atomic method results

Looks good, cone shaped for the atomic cleaning. How do I remove it ? It seems a bit stuck, do I need to force it out ?
