How to do more than 4 colors on a single AMS?

To use more than 4 colors with a single AMS is pretty simple when it comes to HueForges.

Always start the print from either Bambu Studio or Bambu Handy App - This will allow you to map the rolls of filaments to a certain slot in the AMS:

Now map the first 4 colors (which should already be inserted in the AMS to Slots 1 - 2 - 3 - 4
Once thats done move to maping colors 5 - 6 - 7 - 8 to respectively AMS Slots 1 - 2 - 3 - 4 again!

This will allow you to Change the rolls of filament once the printer is done with that color.
For example, in the picture above once we are done with the Black color (Which is usually first) we are going to remove the black roll (you can do that while printing) with White, then once Charcoal Black is done we are going to change that to Red, Dark Gray to Yellow and we are done. ~ You can do that with as many colors as you need!
