Hi,
I think the temperature at the extruder is stable, but the temperature of its surroundings is not.The area around the extruder can get hotter during the print and the temperature affects the PLA, and this could jam the extruder. You can also try to take off the top white cover of the printer in order to cool down a little bit the extruder area.

Good one! Or isolate the printer somehow to keep the temperature higher in case you need that
Hi Sergius!
I took off the cover and it did a little better, it almost finished the job! but then it stopped again
Without the cover I noticed the extruder wasn’t exactly “jammed”, it was more like it cooled down and the filament wasn’t melting anymore. Next step is find a way to keep the temperature higher, as suggested by @derKarsten, hope it works!
Colorfabb’s website reads that they have tested their pla-pha on BTF, I guess it has to work somehow.
Thank you guys!
