Easy multi color printing

Here is my method for multi colored prints.

Start print as normal.

When you are ready to change colors, pause print, raise Z up 10mm, place sheet of paper under hot end to collect extruded waste.

Change filament without moving extruder carriage.

Keep clicking extrude 5mm until the color change is complete. Only about 20 mm with my hot end.

Move z back down 10mm and continue print.

Not very high tech but it works. Pics included.

Nice, this is how I imagined it would be possible to print multiple colours using only one extruder. Perhaps this Thing would be of interest to you. Cut notches in the sharpies to ensure the colour is applied around the circumference of the filament for better results.

Thanks Remondo,

I have tried something similar but only with one texta but didn't like the result.

It was pink instead of red and the color faded into the next and I couldn't really be sure when the color change would feed through my extruder.

With my method, the color change is instant and definite if a bit more labour intensive.
