I’m having an issue with my Lulzbot Mini.
The filament keeps getting jammed in the heatsink. I’ve taken the entire toolhead apart 3 times now, removing the heatsink from the heat block, using an oven to loosen the filament inside so I can pull it out, and soaking it in a solution to dissolve any residue left on the inside. However, each time I reconnect everything, the filament immediately gets jammed again. I am able to heat and extrude once, but once the hot end cools down everything gets stuck.
Does anyone know a fix for this? Or, is there a place where I can buy just the heat sink?
