Sad face. A story of pearls before swine apparently. My @Printrbot Ubis 13S jammed on me the other day (it happens) and apparently I didn’t take time to properly understand the disassembly process. I crushed the ceramic heater core. 
I have a “spare” from the frankenbot that took another lurch this weekend towards being alive.
But the frankenbot will need something, soon, eventually, hopefully…
I was debating buying just the heater core, but for not much more I can get a fully assembled unit, a spare tip, and (focus here for a second as this is important) a “machined heater core key”. Hopefully the next time I’ll be a bit less red-neck with the big pliers, and more diligent in following instructions.
Once again, providing ample support for my brother-in-law’s wise council: Education is never free.
