Migrating MMU3 from Mk3S+ to Core One?
I think it's finally time to bite the bullet and replace my old Mk3S+ with a new Core One. I already have the MMU3 unit for my Mk3, and I'd like to transfer that over to the Core One. I was surprised to find there doesn't seem to be any official instructions for that transition, though there are instructions for transferring the MMU3 from the Mk3S+ to a Mk4, and from a Mk4 to a Core One.
The instructions for the Mk4 to Core One transfer mention that "Core One is only compatible with the latest versions of the MMU3 units, specifically those used on the MK4/S". So does that mean there's no viable upgrade path? The comments on that page seem to imply the only difference is the color and size of the fittings, which can be replaced. Though I know the wiring harness is different for the Mk3 as well, but that can likewise be replaced. I suspect that those items, in addition to the MMU3 Conversion Kit for Core One might be the only parts I need? Maybe also a new PTFE tube? Has anyone else attempted this particular process? Is there anything else I'm overlooking, or some fundamental issue making this upgrade impossible?
Thanks in advance!
