I have a mk2s with mmu. I bought both upgrade to mk2.5s and mmu2. The warning above is confusing. The link clearly doesn’t get my mk2s upgraded. Hoping as I get further into this, the instructions will address that my starting point is not mk2s single material.

I have both the 2.5 and 2.5s kit. Based on title this would take me from 2.0s to 2.5s as one list of instructions. Can you please confirm this is correct as I was told by customer service when purchasing the 2.5S kit there were not instructions for 2.0S to 2.5S. Aslo could I change out just the bed and not do the other parts of the upgrade?

Hi Nate, please follow the current guide if you need to upgrade from MK2/S.

You need to upgrade everything, you can’t just change the bed only.

if i want to upgrade from MK2s to MMU2S i should follow this manual until what step?

Hello!

What I recommend is to follow these instructions until the end and then start this guide [[Topic:Original Prusa i3 MK3S to MMU2S]] from the beginning. That’s the safest way.
