Here is a video of my MMU, I already tested it in print, it works until the moment when the filaments intermingle ...
In addition, my printer is not calibrated at all, it is always in WIP.
So the video just shows the tools change, with the purge.
The base of the printer is a ratrig increased in size, with lots of little tricks.
The head support remains of the hack, because the addition of the servo at the last moment, will require a better integration. And especially to install the cutter at the lowest.
The MMU is a mix of lots of tricks, nottamentally transplanted on the MMU Zblairq, a big thank you! And also at Gravatron3000 for its sample codes.
This is not the final version, but everything is printed, it only remains to mount the 16 elements ...
I used dualdrive from bondtech, because I have a long tube about 1m, it must grow.
The scraper system, allows me to print continuously without using tricks, and especially to eliminate the limits of 6 extruders Simplify3D.
What do you think?
I can make the code and CAD files available if it interests someone.
For the fact, that the filaments intermingle together, I seem to have found a solution, but if you have ideas, examples, I am!
Edit: I forgot to thank DC42 for his help !!
