Solved How to assemble the hot end

I don't know the exact names of the hot end components, so here is what I will use here:

• Body: The large round finned part
• Nozzle: The brass part with the .4mm hole in it
• Square: Actually it's a rectangle and it is where the nozzle, tube, thermistor, and heater connect..
• Tube: The tube that screws into the body and the square

I keep getting stuff oozing out of the hot end and suspect I don't have it assembled correctly. I use a small propane torch to heat the parts during assembly so there should be no gaps caused by filament. but obviously there is somewhere.

There are only two options that I know of:

1. screw the nozzle on tight to the square part, screw the square part onto the tube, and then screw the whole thing into the body.
2. screw the tube into the body, screw the square part way up the tubed, and then screw the nozzle in until it buts up against the tube

In #1, the nozzle is flush against the square part and it also is flush against the tube. The tube is also tight against the body
In #2, the nozzle isn't flush against the square part but it is flush against the tube and the tube is tight against the body.

I have 2 questions: Why is it leaking? Which is the correct assembly?

 

Yes there should be a small gap between the nozzle and the heat block. I'll find you the assembly video. This is the stock hotend correct?

Actually it is an E3D V6 hot end, but I would have thought the assembly for any of them would be the same.

The oozing appears to be from the top of the square, between it and the tube.

Great, I will assemble according to the E3D v6 video.

Thanks for the link!

 

Yeah, I think the gap he shows between the nozzle and the heat block is key. Also, make sure you are using the thermo compound on the threads of the heat break as shown in the assembly page.
