I installed my Mk3 3D Chameleon on the Elegoo Neptune 2S and it is all setup up and I used the Mk3 Gcode generated and put it into prusaslicer. When I start the print it printed the first color and when it goes to switch the second color it just sits at the wipe tower and does not go to the button location to unload filament so it just unloads and reloads the same color and starts printing again.
