Step 1 Preparing MMU1 to MMU2S upgrade kit


YOU CAN'T UPGRADE DIRECTLY FROM MK2S MMU1 to MMU2S !!! You need to upgrade to MK2.5S first.
MK2S to MK2.5S upgrade is no longer being supported and sold as a kit. Please see this article about current upgrading options for MK2/S and MK2.5 printers.
⬢The upgrade process is the following:
⬢Disassemble your MK2S MMU1
⬢Prepare the MMU1 motors for MMU2S assembly
⬢Upgrade your printer to MK2.5S
⬢Upgrade your MK2.5S to MK2.5S MMU2S
