Anyone else getting thermal runaways??

@Martin Bahmann I have had very similar experiences... Small prints are fine but as soon as I tried a big print it clogged up.

I made a profile for prusaslicer and it seems to work much better than the cura profile. No more clogging.

Try setting the default fan speed to 25-30%. That may help.

My temperatures were correct for me but I've heard of others where the temperature are widely off.

I did my first prints today and have the same issues: clogging with 'larger' prints. Going to reassemble the hotend, pid autotune and make a profile for super slicer. The printer came with a silicone sock (at least there was one in my box) and removing it will cause thermal runaways for me , certainly when part cooling is at max

@Dries Douterloigne Same. It seems the fans are angled too high and are cooling the heating block. I still get thermal runaway errors at higher temperature even with the silicon sock with the fans at 100%.

So far I've printed about 1.5 kg of filament for....1 large print, 2 largeish prints and 3 small prints....Just because so much gets wasted with these clogging issues on large prints.

Ooh and the filament runout sensor doesn't work. It triggers but nothing happens.... Another Big print wasted.

Honestly....So far I am quite disappointed with this printer.

- The bed is warped like crazy (+0.8mm up on one side. -0.04mm in the center and +0.46mm on the other side.)

- Clogging issues are a real pain with this printer. Rarely get any clogs on my UM2+ but this one has been nothing but clogs....

- The hotend's quality is....not so good.... I've had to disassemble and reassemble this thing so many times now....Leakage from the heatbreak (I did tighten is properly at 250°C), PTFE tube popping out of the extruder, backflow of filament due to the high pressure causing a jam in the heatbreak, etc.... I am honestly considering high temperature (1000°C) treat-lock to prevent the hotend from unscrewing itself.

- I'm getting nowhere near the print quality shown in the kickstarter.

- Having to wait nearly a month on build instructions....

- Repeated broken promises....

- Bugs in the firmware.

- Bugs in their version of Cura

It works now that I'm using prusaslicer but it isn't living up to its promises so far...

@Akisame - are you sure your ptfe isn’t too long or too short? Best bet would be, just to disassemble everything and reassemble it while carefully following every step in the manual

@Frederik Weis I actually have disassembled and re-assembled it several times already.

I have tried cutting my tube shorter and longer... It doesn't seem to work. I really don't know what to do to get it to work.... Also. Be careful btw. I had one run where the ABL failed and it crashed into my build plate... It is kinda ruined now....

You won't need more than 1mm. Also the Orbiter has a max retract speed of about 30mm/s because of the 7:1 transmission.

The higher the retract distance, the higher the chance to glue your cold end shut.
