I can finally say that this design is perfect for publication. The XHTC is an automatic tool changer based on Renè Jurack's design. To see the procedure for this design I can only recommend the video. There is also a playlist where you can get more information. The design of the STL files is finished, but the whole cabling and control is not yet.
After a nice holiday in Russia and Southern France I get back to you!
So that XHTC is ready for the next winter season (the time where I work most on my projects) I have reworked the entire electronics of the XHypercube and mounted it neatly on an MDF board.
I also improved the small "XHTC Extruder Head" from my last video and got it running.
All this I will present in my next video, so watch my channel https://www.youtube.com/user/xpixer , there will be a new video soon :)
I have sat down to the improvements of the magnet holder. Many things I didn't like so much and so I went back to Fusion 360 to remove some bugs.
The first thing with the tool change, I wasted too much free space with the cables and the too long pogopins, so that I could attach only 2 tool holders on a length of 300mm to my Hypercube. Therefore I had to remove all parts that protruded from the back of the magnet holder. So I built a cable channel for the lower magnetic ball and led all signal cables from above to the pogopins via channels.
The second thing that I never liked is gluing in the magnetic balls. Here I built a kind of press fit, the balls are pressed into the frame and hopefully hold better than with the glue solution.
Otherwise, I'm already so far with the headers that I can try a multicolor printing. More news will follow.
Please check the last picture in the gallery.
The design supports compact tool heads, all electrical connections are only made with one tool change. I'll add more stuff to that. I am currently initiating the change with a script stored under "GCODE Scripts / (before, after) Tool change" in Octoprint from version 1.3.8. You can find the templates in the github: https://github.com/xpix/XHTC
It is still a prototype, but if you want to try it, here is all the information you need.
