Thanks that you like it! Yeah as soon as this version will be finished I'm thinking about publish the files under CC-BY-NC so that the community can use it

BTW: I really love your unconventional tripteron design!

[oliof]

The design is not mine though. That credit goes to Evan Callicoat.

Started working on the Tool-Changer itself

[taconite]

Hey guys,

worked a little bit more on the printer.
I got the first automatic tool change (even if it needs a little more tuning), but it's a first step in the "proof of concept" direction (which I already did with the first prototyp).

@taconite that's a cool design. Where did you get the tapered metal parts?

[taconite]

@fšk thank you
I designed the tool so, that it utalizes standard stock material. The tapered part was done by a friend of mine on a standard lathe.

Tool Change Scripts

Tool Changing of two tools can be seen here:

upcoming is the first multi-material print

@taconite that's a nice tool changer!

@taconite Hey any thoughts about preventing heat-creep after a (hot) tool is placed back on the carousel?

[taconite]

@JoergS5 Thank you
@jpomo10 of course ;). There are multiple options:

1. set the stand-by temperature so low, that a equilibrium is reached
   (+ no additional fans, - long heat up time)

2. one fan for each tool in parking position
   (+ sufficient cooling, - lot of fans with lots of noise)

3. one bigger fan with a fan-duct to direct the air to the heat sinks of the tools in parking position

For now I have no fans at all. So after the first prints I had not a lot of heat creep and no problems with jams. But I guess I will move on with option 3

BTW: I posted another video of the first dual color print on youtube

this looks like a sci fi attack hovercraft

@taconite Thanks for the reply!

Is the tool-changer "carriage" set up as an additional axis? How does it increment along with the Z-axis?

[taconite]

@jpomo10
Yep it is set up as U axis. I wrote a custom post-processing script for cura

Hey guys,

I keep posting small videos - some are not really special but I still want to share them with you: https://youtu.be/6-CR_1vN3cE

In this small video I print with my go-to 100mm/s-profile

And I just uploaded a video of the change of 4 tools

@taconite Thanks for the links!

@jpomo10 Nice to see that others are thinking about options aswell.

To be honest these were my first attempts aswell. The first concept was magnets and the second one permanent-electromagnets after that, but after a lot of testing I decided not to use magnets.

Hello guys,

I went a new way for the cooling of the tools without some parts of the sci fi attack hovercraft.
I added a fan to each tool instead. The data shows that the cooling is sufficient.

[taconite]

Hey guys,

so at the moment the printer is 99% finished. Just some minor modifications need to be done.

If there is interest in the community I will put the files on thingiverse and a BOM and some instructions on github - just let me know.

I'm sure there is a big interest, but the custom CNC parts are cooling down my curiosity.
Why not open a (kickstarter) campaign and sell the required parts?
