Dual use MMU3 on a MK3s+ and MK4s
Hey!
I'm getting a used MK4s with a MMU3 in addition to my MK3S+ and I would like to use the MMU3 on both machines. I already have the information that the Rambo Borad needs a different cable - so I wonder if i could customize an "switch" on the MMU3 where both cables could connect to the controlboard. Are the pins/cables the same? is there a diagram which is which?

it isn't that difficult to disconect/reeconnect a MMU3. The electronics are connected witha single clip at the back.
However, in additon to the new cable you also need to make significant changes to the mk3s+ extruder. The instructions are here https://help.prusa3d.com/guide/9b-mk3s-mk3-5-extruder-mod-kit_420370
I'd absolutely not recommnend going to the effort. People seem happy with the mmu3 when it's with a MK4s and unhappy with the performance on the MK3s+. I have had the mk3s+ with MMU3 since release and it is so frustrating. The worst part is that it works a bit before jamming so I have hope that I can fix it, but it seems to go wrong in new ways each time I disassemble and reeassmble in the hopes of fixing a problem.
