Color mixing problems

Hi,

My name is Ilja and I am the owner of a modded Tevo Tarantula. Which is still a work in progress:



I have added the diamond hotend for color mixing (chinese knock-off). The printer is working well, apart from some tweaking and calibrating. Then I started to print in multicolor with repetier and slic3r, followed this guide: [www.reprap.org]. The result is far off the rainbow colors displayed on the wiki of reprap.

It looks like that the colors arnt mixing together as it should. For example:



When printing orange, there is still a line of yello visible. And when looking from another angle you can distinct the different colors used for mixing.

Im printing 210c PLA


Could this be a temperature issue? Or does this depend on the quality of PLA used, or can it be the cheap diamond hotend?

Thanks in advance

You were sold a lie

mixing extruders like this do not mix!!! There is no such thing (so far) as a real mixing extruder

they extrude toothpaste like extrusion that is a combination of the multiple filaments. Thus you get fun different colors from different angles


Most rely on squishing the colors together at print time by using a fine layer heights

So play with your layer heights
