Can I manually activate the heat core?

So I had a print fail last night and once i took apart my palette it appears the failure was the filament getting stuck in the heat core, dont know why but thats where it seems the failure was. So is it possible to manually heat the core to try and get the filament out of the tube to save it or is this just a bad idea hence the replaceable tubes?

Answer this question I have this problem too

Is this a good question?

Hey @jaykav99, thanks for your question. You can remove the tube from the core (instructions here), and if possible, remove the filament from the tube (you can try submerging it in warm water, sometimes that helps). If you are unable to remove the filament from the tube, please install a new tube in the core. To avoid jams in the future, please turn on endurance mode (settings -> preferences -> endurance), run splice tuning with your filament to make sure you are getting strong, consistent splices (, and make sure your filament has a tolerance of +/- 0.03 mm if possible.

Endurance mode is already on...and last night it happened again on a print that had been running for 17hrs...never had this happen before in the years ive had the palette 2 now two or so weeks into the 2S upgrade and Ive lost 2 tubes. But i guess the answer to my original question is no i cant manually trigger the core.


Hey Jason, no that's correct, unfortunately you cannot manually heat the core in order to help remove the tube. Sometimes a new tube can be prone to a jam on the first print, but if you can salvage that tube for the next print, it's generally more successful. If you provide your shipping address to, we can ship you a new pack of splice tubes to make up for the ones you lost.


Alina, thank you for the offer, I might take you up on that. I did decide to do some splice tuning again this morning I am trying 3,-1,3, and so far so good on the same print as last night. It's got about 12 hours to go so if it finishes I'll chalk it up to being lucky till now...if it locks up again I'll contact support. thank you.
