one question. SZP Coil?
Scanning Z Probe... I think most of this video is relating to the Development kit, and not related to Prusa.

As the print head is pre-assembled I would have assumed the prusa adoption will have the same board inside. And this video is just giving an indication to development kit buyers as to how they can integrate into different systems.
that said I did see a previous interview with Olaf stating the uncertainty around Marlin integration with indx, so possible that Prusa might has some bespoke aspects to the print head board

On the Scanning z probe board from Duet 3d, https://www.duet3d.com/blog/Duet3d-Scanning-Z-Probe
plenty of detail on Duet 3ds website.

Doesn’t look like Bondtech are happy leaving the updates to Prusa! Referring also to a series of videos
Interesting, USB on the board which implies the board is only rated up to 50°. I can't imagine being able to heat the chamber beyond this without some sort of active cooling.

Where does that implication come from? (Not saying it's not real, but I am unaware.)

To be honest, I don't have a source. Probably mis-remembered "internet wisdom". Fact remains though that controlling warping for PC, ASA etc is going to be problematic. Especially with the enlarged chamber. Wonder how this will hold up with an actively heated 60+ chamber assuming such a thing will exist on the C1.
RE: newest INDX picture
all the announcements around indx always mentioned minimum 55+C ... so I'd say the 60C limit of the current coreone remains...

60 is an absolute limit on a well insulated chamber. Typically I can't get it to go above 58. And then there is the fact that the bed has to stay above 115° which causes issues with ASA and most nylons. Also there is some debate as to whether the motors and lubricants used can handle that much heat for long periods. As the bed moves further down the chamber volume increases and so do the temperature gradients.
The ultimate irony is last weekend I went to a local maker space to rent time on an H2D because there was a part for a model rocket I'm making that cannot be printed successfully on a Core One. Otherwise, the C1 is a great work-horse printer. Seems however I've outgrown mine.
Back on topic, I'll pick up and install the INDX and have a play around with it for a few months to help work out the issues but there is now a very high probability that my main printer will be an H2D and the C1 will eventually be donated to a local school. Or maybe I'll keep it around for the very rare occasion I need something multi-color.

the very rare occasion I need something multi-color
This was the main reason i waited for so long to buy mmu3. Boy was i wrong! Now i see that the point of mmu3, at least for my needs isn’t only in multicolor capability, but perhaps even more the fact that i can always have more colors and types of filament to choose from without changing it each time. I usually have mix of pla and petg: usually blacks ,whites and some other one.
If i’ve read correctly then Indx will have even greater option: the ability to have different nozzle sizes installed. Like, for example 2 x 0.2mm, 4 x 0.4mm and 2 x 0.6mm. That way will printer really become multi-tool…

Just buy one already 🤣
You’ve obviously made your mind up, and seem to spend most of your time on here moaning about your C1.
We’ll see you back here in a few months when you realise the grass isn’t always greener and your house has burnt down 😜
I’m only joking of course mate.
RE:

just be sure to have a solid plan how to keep it dry. I had the same idea, keep filament loaded in the MMU so it's ready to print with minimum hassle. But I abandoned that, the importance of dry filament can't be overstated. I think it works for some but of course it depends on relative humidity and the material being printed.

Fair enough. When I started my astronomy hobby I bought a decent telescope but quickly realized it wasn't good enough. Now I have 7! and will probably downsize to 3. Not sure I want to do the same with 3d printing. I might take the Highlander approach "There can be only one..." If I can successfully accomplish what I need to do on the C1 INDX only then I'll stop whinging... I promise 🤣 I still can't stop looking at the H2D and thinking "Ooohh... shiny..."
RE: newest INDX picture
Like most hobbies mate, they’re a slippery slope !
RE: newest INDX picture
It's a fine line to walk but hey, there's also personal growth and that's what hobbies are for.
There are worse ways to spend the money, as in "unhealthy hp/kg ratio".
The recent XL-discount marketing mail got me thinking - MMU is nice - using at least every 2nd print - but pretty much a dead end for any serious application beyond colorchanging. Yes, I think I do need this in the long run.
Core One already gave me a pretty good idea what "Original Prusa" stands for so that purchasing decision was surprisingly easy 🙂

I'm planning on the 8 tool INDX. For that I'm figuring I'll have my SUNLU S4 dryer on one side to feed 4 filaments, with another SUNLU S4 dryer on the other. That way I can have two material types being fed, all of which are dry.

Sounds like a good plan and I hope it'll work out.
Supporting evidence for my scepticism (besides too many ASA-prints separating along layer lines): I keep three-dot moisture indicator cards from semiconductor material with spools and in bags. They are always all-clear during and immediately after the drying process. But only then - moisture creeps in once the air in the box cools down, even in my SpacePi X4 with built-in desiccant compartments.
Not saying this can't be managed but e.g. having the first meter of filament with unknown humidity is one more complication I just don't need, given it's easily avoided - if only for the annoyance of oozing filament during nozzle clean / bed probe stages.
