Failed print and hardened filament encased the entire hot end

[paulrhee2002 2]

Hello all,

Hope everyone is doing well and thanks for any help in advance.

I have a failed print and the hardened filament encased the entire hot end.

Wanted to just heat up the hotend and try to melt it but my tevo black widow will not let me get past the home screen where I get a "mintemp" error message.

Any help is greatly appreciated!

Do you have a heat gun or soldering iron you can apply to the plastic? 

 

At best, all the filament around your printhead is acting as a heat sink and and causing the error; at worst your heater and/or temperature sensor may be damaged (I'm not familiar with the Tevo) and the error is there to make sure you don't have thermal runaway. 

 

Best bet is to apply an external heat source and pull material away with pliers or similar.

So the heat sink thing is probably wishful thinking on my part?

Hopefully it's fixable and will get a soldering iron.

I'm fairly new to 3d printing so today I learned heat sink and soldering iron.

Thanks so much Erin!

It might just be a heat sink issues, but it's also possible hardware damage, so you're definitely safer using an external heat source. Good luck!
