Before starting the print, we recommend applying bed adhesive to the print bed.
If you are going to do a multi-filament print, you should advance the first filament to be used up to the nozzle. You should manually advance the other filaments to be used to the position shown in the picture on the ChromaHead.
If you're doing a single filament print, advance the filament up to the nozzle.
To advance the filament up to the nozzle, first move the filament inside the ChromaHead as far as you can until it reaches the extruder gears, then stop. After that, manually advance the filament in the Extruder menu on the ChromaPad. If you have a multi-filament setup, you can select which filament to advance from the menu.
