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.
