i notice when trying to print with a single color that is T0 it never loads the filament why?
i have added this to my G-code and it works for every filament but T0
{if previous_extruder==-1}
G1 Z0.28 F240
G92 E0
G1 Y10 E75 F1500 ; prime the nozzle
G92 E0
{endif}
Single colors prints should use the normal printer's profile and not the 3DChameleon profile. Also, you need to manually load the filament all the way to the extruder, just like the 3DChameleon wasn't installed. You can use any of the extruders to do that, or you can even bypass the 3DChameleon altogether by inserting the filament in to the middle of the top of the Y adapter (using the bypass hole) to load the extruder directly.
