Correct Manual for MK2.5 MMU2 -> MK2.5s MMU2S

Hi all,

I received my MMU2S upgrade today and can't find a set of instructions that spell out what is needed to just got from the MK2.5 with MMU2 to the 2.5S with MMU2s. Has anybody completed the upgrade and if so, what instructions did you follow.

Thanks!

Will

I completed the upgrade, the info is scattered over many manuals.
Start here: https://manual.prusa3d.com/Guide/1.+Introduction/1037?lang=en
For those upgrading MMU2 to MMU2S, please follow chapters 2 and 3 to rebuild the extruder, then skip to chapter 6 (around step 22), assemble buffer in 7 and calibrate printer according to chapter 8.

I recommend you read the manual very closely. It will guide you to different sections of the manual depending on whether you are upgrading an MK3 or an MK2.5.

Thanks all that responded. Starting with the link that Jan provided, you can make your way through but as Eric mentioned, you need to follow very closely. It isn't always clear where to start and stop within a section of instructions. I got my upgrade completed and just finished z calibration. I had a battle with the IR sensor. The chimney seems to be very picky and there wasn't a lot of room to adjust it to the left as the instructions mention.
I'm expecting some issues with it in the future but it seems to be giving a valid reading at the moment. Hopefully I can kick off a test print later tonight or tomorrow.

The starting link should really be documented somewhere clearly (possibly in the readme which comes with the downloadable parts or gcodes), I had to find this post in order to work out where to begin. Of course, once in, the manuals are excellent as usual but it would be a pain to go down the wrong path. I guess it has become quite a challenge now with so many potential upgrade paths.
