I have an um3 that has worked flawlessly for over 8 months, in the last week now I have had 2 separate build cores end up with filament stuck in them where it will not unload or push through. Nothing will help.
1 core now has filament stuck in the heat break and it snapped just below were the filament goes into the core. the 2nd one hasn't snapped off but I can't get it to move even at 280cc and I'm afraid to mess with it.
I bought a new core to replace the first assuming it was a fluke but now it happened to my second core in less than a week. Using curator 2.7beta and two different types of filaments where used that were pla.
Anyone have ideas? I have printed with this for 8 months with no issues.
