This is an upgrade for the original MMU 1 to the MMU2S. This enhanced version is much simpler than the original MMU, which makes it easier to use and less sensitive to the quality of filaments. If you have an MK2/S, you have to purchase the MK2/S to MK2.5S upgrade kit separately.

This is not a full MMU2S upgrade! If you don't have the Multi Material yet, please, buy the MK3S Multi Material 2S upgrade.
