Hi ! My print of "CUTE KOALA Keychain" by "CUBE3DWORLD" Printer: "Ender-3 V3 SE" File "HEAD.obj" and "BODY.obj" in the same print. Scale: 100% Sliced with: Creality Print v4.3.6 (material "CR-PLA", quality "Normal") (Quality ->) Layer height: 0.1 mm (Infill ->) Infill Density: 50 % (Suppoort ->) Generate Support: Yes, Support Structure: Normal (Build Plate Adhesion ->) Bluid Plate Adhesion Type: skirt Filament used: ArianePlast PLA+ Silk gris, ArianePlast PLA+ Silk rose, PLA noir Velleman. Printing time: ~ 0h40 As I did not understand/find if it was possible to request a change of filament with insertion of an M600 g-code under Creality Print at a given layer, I edited the resulting .gcode file with NotePad++ to put where it was necessary, g-code “M600” instructions (Filament Change) I used "Prusa Slicer Gcode-viewer" to identify the positions where to insert g-code M600 commands (filament change). Because unlike "Creality Print", "Prusa Slicer Gcode-viewer" displays the details of the g-code instruction sequences with their line numbers when you preview a layer step by step. I tried 3 filament changes Starting from a gray filament, a first M600 to have pink on the last layer of the inside of the ears (but it's not really visible), then a second M600 to return to gray, and further on a third and last M600 to go black just before the layers for the eyes and nose. After removing the printing supports, quickly scraping off small defects and assembly.
