How can I print in multicolor with Ender 6? I'd like to make multicolor printing on Ender 6, but it seems that the filament change (ADVANCED_PAUSE_FEATURE) doesn't work (it works on my Ender 3).
Can you help me how can I solve that? How can I make the ADVANCED_PAUSE_FEATURE available on Ender 6?
Enabling ADVANCED_PAUSE_FEATURE requires a rebuild and upload/install of a new Marlin firmware. The option is found in the advanced configuration file (Configuration_adv.h).
Please change:
//#define ADVANCED_PAUSE_FEATURE

to:
#define ADVANCED_PAUSE_FEATURE

Rebuild and install the firmware.
