I purchased a bimetallic heat break (copper/titanium) for my Ender 3 Pro.
In short order, I have had two horrible clogs. It heat creeps so bad, that I had to torch the heat break to get the filament out after disassembly.
Both of the bimetallic ones did the same thing.
I’m currently back to the original Swiss Micro heat break, until I get this figured out.
Anyone heard of this? I’ve never seen filament stuck so hard.
Maybe a Spider hot end would be a better idea……
