Connecting MMU2S unit to the printer differs depending on the printer you have. For the MK3S/+, please use this step. For the MK2.5S please skip to the next.
⬢MMU2S Signal cable (upper row of the pins, brown wire in the connector facing left)
⬢IR filament sensor cable (white wire facing left)
Make sure the signal cable is properly connected to all pins!
⬢Power cable (add it to the first two clamps from the left, leave the PSU cables connected). Red wire is positive and in the first slot, black wire is negative and in the second.
⬢The power cable connector "fork" has bended ends, make sure they point up, see the picture.
Make sure the power cables are tightened firmly!
Use the Philips screw-driver to release the screws on the EINSY Rambo board.
