Color mixing the ugly duckling

any other location where this will be published? github for example? Would love to see further development of this

Please find all files at http://repables.com/r/291/http://repables.com/r/291/ , am still working with it.

Great idea... 4 extruders would be great, but 3 is a good start... I use a Makerbot 2X, but am building my own larger printer. I hope to try this extruder out shortly. Any chance you could post details on the settings/code required to enable filament retraction? I just started investigating Slic3r. Thanks.

will there be a bowden version? Because I have a delta printer this extruder wont fit my printer. Would bowden even work for this type of extruder?

Nice! is the small square on the side to allow for the colour change? can you avoid that and do straight colour mixes?

Yes the hole needs a block put in it that has a hole, will upload a part soon, its to have an accessible place to remove blockages and provide a guide for the filament, and so the design can be changed to feed better without making whole extruder, am still trying to get the perfect shape for this. Colour mixing is not all that possible just yet but have ideas, main issues is that only one extruder can be driven at at time, for mixing extruders need to drive 2 at different rates etc so for now happy to be able to swap colours

How do you get the slicer to use two extruders and only one nozzle? I have tried this, and it tends to have a fit that there is only one thermistor, and won't print.

In slic3r or cura am setting all temps to 0°C , this allows you to set your own and you won't get the errors, set temp for extruder 1 manually before printing, I use lcd control panel to adjust temps.

Hi . What program do you use to print and use triple extrude. And how do you tel it to print om the side for the collour to came out before it print further .

Using Cura currently for 2 colour examples, will be changing to slic3r this weekend for 3 as it supports more colours. The priming tower is a Cura option. In slic3r a similar way is to make a thick skirt around object

Please as programming control units or funcionamiento. gracias ..

please could you use the thingiverse zip function for these files,I hate having to save individual files as they just get mixed up with other files, and it is a smaller file with the Zip to download, and the Zip keeps all the files together so I can unzip the zip file when I want to gcode the files and print them.

Grandeeeee!!!! Yheeea!
