MK3S + MMU2S upgrade to MK3S+

Hi there,

I currently have the MK3S with MMU2s attachment. I just bought the MK3S+ upgrade and I wanted to know what upgrade instructions to use.

The current instructions are for MK3S to MK3s+ but nothing that mentions if the MMU2s is already attached. 

I wanted to know if there are some steps that should be modified or skipped in order to accomodate the changes that are already made when the MMU2s was added.

Mk3S to MMU2 was pretty much rebuild extruder to have a sensor tower + add reverse bowden tube connector and upgrade the  firmware

Mk3s+ needs to change Y rod supports, Ybearing fixings, revise the X axis  and rebuild the extruder...  I suspect you need to do all of the Mk3S+ upgrade, but when doing the Extruder follow the mk3s+ to MMU 2S upgrade steps instead and load the correct firmware to the printer and the MMU2S

then adjust the supapinda, manually, and run a full configuration, including deleting old settings
