Superman Dual extruder Tri-colour trick

thingiverse

Misc Notes: To combine dual color models in your slicer, select both and click "merge" after assigning different extruders for each model. 3 Colors from 2: This is one single print featuring three colors from a dual extruder by using hot swapping without pausing the print. When blue finishes printing and red starts printing about halfway up, slow down the print speed while pulling out the blue filament and adding yellow. I made this mistake by removing it too early while still extruding blue, but it didn't affect the infill and came out fine. You'll need a large purge block due to strong color changes in yellow, red, and blue. I've added Cura 3.5 Gcode to replicate exactly as shown. I lowered print speed to 80% during printing because my jerk settings were high.
