this is super cool man... great work!

Have you thought about using it to print colored 3d models?

Essentially, one could activate the dye when gcode Switch from E0 to E1. Off course it need to look ahead in the gcode to guess in advance when to switch the dye on(taking into account the physical filament lenght distance of the dye mechanism to the extruder), so the colored filament gets in the extruder at the right moment when it was supposed to switch to E1.

This opens the door to do proper colored prints with a single extruder, very much in the same way as mosaic palette (google it if you dont known! Pretty cool), but at a fraction of the cost!

It has the potential to become an very affordable diy option for print in multiple colors!

I'm definetely going to print this rig and do some experimenting... let me known and we could join forces! I'm good with programing!! ;)

What about a 3 dye pen version... red, green and blue?!?! Or 5 CMYKB?!?! Lol

Wow! This is super cool!
When I posted that Futaba library I couldn't even imagine that it would be used for something this cool. I'm glad you found it useful.
You mentioned that the wire guide wasn't quite right. If you can give me some specifics, I would be happy to modify it or point you to the spot in the .SCAD file where it is set up so you can fiddle with it.

thank you! you're all good. the bump on the front was fine - the terminals on my servo was bigger than the hole i originally made. i'll update the rhino file soon.

What an interesting idea. I found that the filament needed to be fully coated in sharpie in order to achieve any kind of brilliance. There was a kick starter product that was clipping and melting together 4 different colors of filament as needed based on the STL file. The other idea I had was using the ink from an ink jet printer to coat the filament any color as needed to get full color models.

thank you! yes - i find/found that i had to color in the filament for at least half the circumference of a given length of plastic to get good solid, strong colors in the print. the hot end definitely knocks the zap out of all but the strongest hues. i found that pigmented fabric markers designed for polyester textiles work well on PET+ and Nylon filaments. i plan to mod this project to include 3-4 servos and therefore increase the pen count by the same factor - and hopefully cover more material that way. i backed the "Mosaic" kickstarter - and i am looking fwd to getting their device asap.
