Filament doesn't fit through Rapido heat break
I'm getting my printer ready for its first print. When I tried to print, though, my extruder was skipping and the filament wasn't advancing. It appeared that there was a problem somewhere in the hotend (based on how far the filament was able to advance before it stopped), so I took the whole thing apart. It turns out that my filament- nice, regularly-sized 1.75mm filament from Atomic Filaments- doesn't fit through the opening to the heat break in the Rapido. The top part (the part that goes in the cooled area) is just a little too narrow. I ran the filament through backwards (removed nozzle pushed through heat break) and it gets almost to the top before it can't pass. Has this happened to anyone else? What do I do about this?
