Upgrading MK3S+ MMU2S to MK4 MMU3
I purchased an MK3S+ -> MK4 upgrade and an MMU2S -> MMU3 upgrade that should arrive shortly. Currently my MK3S+ is connected to the MMU2S, how would you go about doing the upgrade? Are there any instructions available for a simultaneous upgrade?
Also, the available G-codes for the parts that need to be printed are either for the MK3S+ or for the MK4, would they work with the MMU2S or would I need to reslice them? Are the MMU3 G-codes that are sliced for the MK3S+ compatible with an MMU3 that will be connected to an MK4?
Thanks 🙂

In case anyone has the same problem, I ended up first printing the MK3S+ -> MK4 upgrade parts by pre-loading the filament into the nozzle and printing the g-codes provided by Prusa. The printer gives a warning that this is the wrong printer and I just told it that this is ok. Prints came out great (with the new satin sheet I bought).
I then disconnected the MMU2S according to the first 6 steps in the MMU2S -> MMU3 upgrade instructions and proceeded to do the MK3S+ -> MK4 upgrade.
Now I have the vanilla MK4 running well and am printing the parts for the MMU2S -> MMU3 upgrade with the g-codes provided by Prusa. Next I'll do the MMU2S -> MMU3 upgrade.
This pathway works well so far and I don't foresee any problems with the last upgrade at this point.

Yes, that would also be my recommendation (and it's also Prusa's): Du the MK3s+ to MK4 upgrade first, and only if everything is working well, do connect the MMU3 (after upgrading it from MMU2S to MMU3).
