⬢For the following steps, please prepare:
⬢Adapter-printer-mmu2s
The package should include only the orange adapter. If you have printed parts yourself, please don't use the version with the hole for steel ball.
12/2020: The printed parts were slightly updated and the look may differ from those on the photos in this chapter. However, the assembly is the same.

after finishing the upgrade when I try to turn the filiment sensor on it says that it’s “not responding”. also what is this upgrade supposed to do anyway?

Hello Caleb, please double check your sensor connectors on both ends - ensure they are properly inserted.

I also deferred the extruder upgrade until after assembling the MMU to minimize downtime.

As so often i didn’t find the part at first (my fault).
Please consider using the bag “name“ (like “5. E-AXIS“) when referring to parts. Happened also during the assembly of the printer itself quite often especially when looking for scres and nuts.

Gone through all the packages twice but did not find the orange adapter, where should it be?

Hello. It should be in the bag MMU2S EXTRUDER. If it's not there, the part can be easily printed. Here's where you can download the stl file: https://www.prusa3d.com/prusa-i3-printable-parts/

I thought I didn't get this bag, because it isn't in the printed parts box. It was under the cardboard flap in the bottom of the box, under the spool holder trays!

Are there any hidden problems with moving section 3B to after 7 so the printer is not disabled while 4, 5, 6 and 7 are completed? It might be useful to minimize printer downtime while the other steps that do not appear to directly affect printer operation are accomplished. Once the extruder is disassembled it might be some time before 3d printing can begin again.

Hi, you can assemble the MMU2S before re-assembling your extruder - it won’t cause any problems.
