My heat brake is leaking ????

Post by ksor » October 11th, 2019, 12:31 pm

I have a CR10s PRO that's broken down ... again !

That threaded tube between heating element and the cooling is leaking melted filament big time !

I saw a video where it was said that the threading is 6mm threats - I think it's an undersize 6mm compared with my 6mm threading tools !

What is the right thread size and what can I use to "pack" the threads ?

I do not have a CR10 Pro, though when my 3D Printer has a leak I fix by what ever needs are required.
If this means the the Heat Pipe be replaced I replace the heat pipe, If the Heat block needs replaced replace.

At times it may require a replacement of more than one part, this is what is about to happen on my 3D Printer.
Both need to be completely dissembled and a diagnostic done to determine which part require replacement.
The throat (Heat Tube) of my 3D Printers is lined with PTFE tubing and after a while gets deformed.

I will be inspecting all parts while the hot-end is dissembled, when rebuilt will be close to a brand new hot-end.

I do too ... the problem though is I don't know the thread size and what to use as packing material - in fact that's why I asked my question.
