Filament Stuck! HELP!
I've just received my new CoreONE and have enjoyed it for the first couple of prints. The print quality has been fine... but then the filament STUCK. the system kept printing NOTHING... and I can't remove the filament at all. Tried CHANGE filament, UNLOAD filament, NOTHING... just totally STUCK. Tried increasing the temperature... all to no avail. This is weird since I'm still on the first demo spool of PLA that came with the unit.
Perhaps something is wrong with my unit?

I have noticed the Core One is not user freindly in this instance. The MK4 you can Unload and pull on the filament while unloading. See if they have posted help on this in the knowledgebase or contact [email protected] for the Core One.
If there is no sound while trying to undload/load there may be a groove cut in the filament. If there is a continual clicking sound from the nextruder when it should be feeding, the nozzle may be plugged. The clicking is the servo failing to turn or advance when pushing the filament.
I would try the following in order.
1. unloading. When up to temp in the unload process put a firm pull on the filament from outside the Core One. To help pull it out of the nextruder.
2. After cooling, Open the idler and see if I could push the filament out to grab it, cut it and then take out the nozzle and pull out the filament out of the nozzle. You could heat the nozzle in boiling water then pull out the filament, similar to a cold pull. Tools and hand protection needed.
Sometimes the nextruder can cut a groove in the filament and it wont pull/push it after. This can happen when the filament is stuck hard on a roll. Sometimes when the end of the roll is reached and the filament has a hook on the end that wont let go or wont go through the PTFE tube. Also when there are hundreds of small details combined on a layer with near 0 advance of filament, the constant advance/retract in the same place can wear a groove.

Thanks - I'll see if I can follow those instructions and fix this myself.

Did you manage to sort the issue?
I'm having exactly the same problem.

RE:
What I did, when I clogged my 0.25 mm nozzle a few times:
- Open the extruder idler. Left side of the nextruder, flip the little clamp up and move the bigger lever with the extruder idler away from the filament.
- Check how it looks. Is the extruder gear full of filament particles or does it look kinda fine?
- Main menu, control, set the nozzle to 270°C for PLA.
- Control - move axis - extruder: when the nozzle passes 220°C, start to push the filament on the side into the ptfe tube and move the extruder "+", so it doesn't restrict, but helps you pushing the filament.
- Keep the pressure with your right hand on the filament on the side and every few seconds, give the extruder axis a few steps forwards.
- At some temperature, the nozzle might make a popping sound and a big blob will come out of the nozzle.
- Immediately go to controls - temperature - cool down.
- Then back to move axis - extruder and keep the filament flowing, while still pushing it, to not get heat creep and clog it again!
- At around 210°C, you can stop pushing + slowly moving the extruder axis.
- Close the extruder and continue printing.
Keep your room nicely ventilated while doing this! Pushing a blob of PLA through the 270°C nozzle definitely doesn't seem/smell healthy!
With my mk3s, this is a lot simpler, since the extruder gear completely disengages, when taking out the extruder idler tensioning screw. And being able to push the filament from 2 cm above the extruder is a lot easier.
Just heating up the nozzle and keep pushing, until the blob comes out. With the Core One, I have to control the extruder gear, since it rubs against the filament quite a lot, even without the idler..

How do you even open the idler? Ther isn't clear instructions anywhere, very frustrating.
