V2 Hot End

Recommended Posts

Had some questions about assembly.

Do I have to replace all the wood on the head? Or can I get away with just changing certain pieces (like the top and bottom).

Any tips on pulling out the old thermocouple and cartridge heater from the old aluminium block? Should I heat it up before trying to remove?

If there's anything you found to watch out for, or anything to make my life easier, please let me know.

Mhh, you _should_ at least replace all the wood on the head. Can't say if it is possible to kludge something when not doing.

For disassembling / pulling out the thermocouple and heater (and all party that get heated in use) -> it's always a good idea to warm / heat things that you need to remove, be it "slid in" or "screwed in". Ask any car mechanic :-)

Regarding to the wood, it is not necessary to change the sides of the housing.

The new wood has, i believe, 2 new small holes in it what makes it easier to guide wires from the outside with a screwdriver. If you don't want this luxury you don't have to swap them :)

The top and bottom are mandatory tho.

As for further guidelines i would like to refer to the wiki and look at the pictures.

Don't use any excessive force for anything but make sure the hot end part is tight.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
