@3DogNate:
Did the heat break bend while you disassembled the hot end while it was cold.
I didn't find a reference in the E3D assembly instructions of how to disassemble the hot end, can some one share there experience.
I've designed tooling for hot plate fusion welding of plastics, and for me it's easier to disassemble if it's on the warm side.
To help reduce the torque to unscrew the E3D heat break, I think disassembly could be made easier if it was warmed up.
I don't want to make a temperature suggestion, because it's really easy to strip out the threads in aluminum when it's hot.
I don't know what the best practice is for the E3D, you should inquirer.

3DogNate I am in the middle of building a printer and plan on using the same combination of extruder and E3D except I will be using the bulldogXL. How did you account for the size mismatch between the e3D and bulldog mount? Did you use a metal shim or something else? I skimmed your posts and didn't see if you explained that yet.
I see you have quite a lot of fans on your print head. Have you tried pointing them all at the barrel while printing? This isn't a fix but it might help narrow down your problem to thermal or mechanical.
I turned a press fit bushing for the top ring of the heat sink on the lathe to fit the bulldog with no slop. The heater cartridge has no problems keeping a constant temp even with the PLA cooling fans blowing.

Hello everyone, I am wondering how E3D gets the inside of the heat breaks polished? I look inside of one and it looks smooth, I am trying to do a water cooled metal hot end but I can't make the center channel on the heat break smooth I always get tool marks, I was looking through the post and I saw some tips on how to do it most of them are manually polishing the heat break, if I am doing just one is fine but if I want to do a bunch is not something viable there has to be a better way, any of you guys know how? Thank you.

Thank you for the input thejollygrimreaper, however that is what I am trying to avoid doing manual polishing, there has to be a better way, I do not think that E3D hand polishes one by one. I was reading about some kind of electric polishing but I had not done any more research on it. Anyone else has any ideas? Thank you.

Try a reamer.

What are folks running for retract distance with the E3D hotend, 1.75mm bowden version?
I realize this takes a bit of tweaking for each individual extruder/tube setup, but it would be useful to know a typical successful distance.

I'm not worried about if the heater cartridge is keeping up. There is a chance that the fan on the barrel isn't enough to keep the heatsink cool. Try pointing an extra fan at the barrel while it is printing to see if it stops jamming, if it does its a cooling issue. If that has no affect then the problem is somewhere else. You may also want to try flipping the barrel fan from push to pull to see if that makes a difference.

What is the process for removing the nozzle from a used E3D?
