Hello, I had a failed printed on my Ultimaker 3 that I didn't notice. The filament backed up (badly) into the two print cores, but mostly into core 2. I am trying to remove the excess filament, but it is a glob.
The good news is that the UM3 will still extrude filament from both nozzles.
The bad news is that it is so jammed, I can't change the print cores.
I keep heating up the print cores and trying to scrape off the blobbed material. I then use a need nose pliers to pull stuff off. I then cool it down and try again.
Any ideas on how to remove the GLOB?
