As I promised before, I will make the Kraken open source. Well, not the original, but an upside down version, but there’s not too much difference between that, and the normal one. A lot of things happened. In short: I still have a lot to do with it, as I’m doing it alone in my free time, but I’m progressing slowly (I have to get the names in order, check that everything is in the files, some assembly instructions, etc. I don’t want anyone to die in the progress of building a Kraken). I will provide the firmware if I can find it. It will need a lot of tinkering to do, but I think there are a lot of pro 3D printer enthusiast who can finish it.
I intend to upload the necessary stuff in the following order:
- extruder module. You can find the parts here.
- arms Coming soon.
- bottom module Coming soon.
In order to build your own Kraken, you will need the following equipment:
- hex wrench for m5 screws, and nuts,
- m3 screwdriver (for the screws you will use, I recommend countersunk cross recessed, or hexagon socket),
- a hammer,
- some beer,
- lots of patience,
- soldering iron,
- and some experience building machines.
Some parts must be laser cut, and bent, so I recommend finding a supplier for that. All parts are designed for steel, except for the arms, which I intended to make out of aluminium.
I will provide a detailed BOM later, but here’s what you will need for the extruder module:
- 40mm fan: 1pc
- E3D v6/lite (use an original, it’s better than the clones): 1pc
- m3x8mm: 3pcs
- m3x16mm (or the right ones for your fan) 4pcs
- m3 nuts: 4pcs
- 3D printed parts: 3pcs
- endstop: 1pc
- magnet: 3pcs
- All printed parts 1-1 pc
- Assemble the hotend
- Put the part named clamping part on the hotend, with the bent edge pointing towards the nozzle
- Put the positioner around the neck of the hotend, place your endstop at the two small spikes. The lever should face towards the inlet at the hotend.
- Screw these two parts together
- Place a 40mm (10mm thin) fan inside the bottom cover
- Install the magnets to the 3 holes on the module (use some glue if you want, but it holds well press fitted)
- Install the hotend to the housing. You should first pull the cables through the hole on the top.
- Place the part named cover top to its place
Printing instructions: at least 35% infill, 2 perimeters.
After assembling, it should look like this (except for the J-head):
I will upload the other parts of the printer with the exact names, after I renamed everything to something normal (currently some of them are called “small thing”, “hotfix” “strange wobbly stuff”, and similar).
All parts will be provided in .step, format, and printable parts in .stl
