RE: INDX is coming for CoreOne?
Posted by: @darksharpie
Also interesting a Core ONE L with AFU and 8 tools is around the same price as an H2C with the recommended 2 AMS units and 7 nozzles.
That is a great point. It probably makes it a superior value.

RE:
Now here's the really fundamental "Core One with INDX" question:
On a fully loaded INDX configuration with 8 nozzles -- where is the poor Core One going to do its headbanging for XY homing? 😋
RE: INDX is coming for CoreOne?
just bang on y max.
RE: INDX is coming for CoreOne?
Wasn't following the thread for a day. People were earlier asking about nozzle hardening.
During that live stream the Bondtech people said that right now the nozzles that they were showing were nitrided, but there would be different options by the time real orders will be placed by people. At least that's how I remember it.
I'm looking forward to the INDX as I hate the poop-everest producing multi-material options and the MMU3 didn't quite appeal as I'd want to run residue sensitive materials. Thus having a nozzle strictly tied to one material should really work well. I expect to mostly use it for functional prints with different support or separation materials. There are really cool things you can do with TPU and PLA or PETG separation layers like printing bellows (cf. FPF videos).
RE:
Interesting little bit of info from Mikolas over on Reddit.
Bondtech guys have the INDX running at 360 "easily"... and he thinks sub 10s swaps by the time it ships.
Looks like they were (understandably) playing it safe at Formnext.
RE: INDX is coming for CoreOne?
And there are a few integration questions which I am wondering about. E.g. it seems we are losing the side filament sensor. So how will filament runout detection -- and in particular unloading of the remaining bit of filament -- work with only a printhead sensor? (Or will it be a printhead sensor?? I can't quite see how that works with the exchangeable tube & nozzle combos. It's listed as "will be there for the Core One version, but is not implemented on the Formnext demo unit" in the INDX specs.)
While I’m not 100% how’d you’d wire it back to the buddy board, without cutting a hole on the case or acrylic, but the ptfe tubing holder on the sides are pretty over sized. They have more than enough space for a filament sensor/s to catch run out prior to getting to the extruder. 
RE: INDX is coming for CoreOne?
Yeah I'm pretty sure it was mentioned at Formnext there will be filament sensors where you've circled.
RE: INDX is coming for CoreOne?
Remember, although Prusa are pushing this, it is not a Prusa solution. This is a Bondtech solution and can be purchased from them (Prusa may sell on their online store at a later date). Nice to see companies work together like this though, thats for sure.

The core technology (no pun intended) was developed by Bondtech, no doubt. And apparently they get an initial period where they take the full revenue by selling direct, also for the upgrades they sell to Core One users.
But the Core One integration -- including in particular the firmware, with bed probing, filament sensor etc. -- must have been done largely by Prusa. They have presented this as a co-development between the two companies, and they have already committed to selling it via the Prusa channel too.
My guess is that Prusa would have preferred more control: Selling via their store right from the start; maybe not selling generic upgrade kits at all but keeping the technology exclusive to Prusa; maybe acquiring Bondtech as a whole. But Bondtech wanted to retain their brand and their independence, and had a pretty strong bargaining position. It looks like Prusa at least got an "exclusive OEM partnership" as far as tailored, ready-to-install solutions are concerned.
RE:

Agree. This sort of collaboration is what is needed to push innovation forward. If the INDX system turns out to be more flexible and less error and maintenance prone (I'm speculating here) than the Vortek then I can see Prusa staying relevant in the consumer space for some time.
The Core One still has this Brutalist architecture (or maybe steam punk) vibe but it's growing on me. I've received confirmation that I'll be the lucky recipient of the Bondtech INDX Founder's (beta) Edition so maybe I'll cancel the U1 pre-order after all.
Now where is my actively heated chamber?

On the topic of a heated chamber, is it easy enough to achieve on a standard CoreOne?

Passive heating with the heat bed can reach 55C. Problem is there is uncertainty on whether or not the Love Board electronics can handle heating above 60C and then there are the acrylic panels and door that will warp at higher temperatures. Some of the plastics I want to work with need a 60+ chamber temp. I may need to go to a different brand for that.
I thought about insulating the chamber with something like this: Reflective Bubble Insulation Sheet
RE:
You're right. 60-65C+ chamber temp is not this printer. Achieving 60 relative quickly and keeping it stable on the other hand is quite easy with minimal insulation and electronics though.
I usually use a heatgun on low heat to warm up the inside while the printer doing its preparation. When the heat absorbtion routine comes, the printer is up to temp and only drops a few degrees. Just before the absorbtion finishes, I give it a few secs of extra heating to gain back what it loose and it stays stable till the end around 55C.
The main benefit could be for the active heating besides the quicker warming up is that it could maintain 55C even with lower bed temps. I don't know if it is a real scenario or not. Materials I use are usually requires 110C heatbed.

With decent ambient temp mine can reach 58C in standard form with just a little extra sheet on the top, thats where most of the heat goes away (i have corner pieces aswell). So plan is to try ran at 60 or close stable with my heater(see the other thread), since its so close anyway. The biggest issue is the heat up times with cold ambient temps, takes ages, not anymore though 🙂
RE:
Interested to see what the nozzle size options are for the pre-orders…ideally will be able to mix and match.
4 x 0.4mm , 2 x 0.6mm and 2 x 0.25mm would be the ideal scenario for me.
Being able to have such a variety of filaments and nozzle sizes all loaded and ready to print is pretty wild.
RE: INDX is coming for CoreOne?
When the INDX arrives I'll have a Nextruder and $500 worth of nozzles that I can no longer use... Really wish I kept the leftovers from my MK4S conversion.

Ever since the rumours Core One would get INDX I’ve held off buying any nozzles, I’ve only bought the Obxidian HF and used it pretty much non stop since I built the machine. Really pleased I waited, just fingers crossed my Obxidian can hold out until the INDX ships.
That things been a beast though, I’ve pumped countless kg of fibre filled filaments through it over the last 6-8 months, only had one clog which was pretty easy to push through.
RE: INDX is coming for CoreOne?
@hyiger
haha, I still have my leftovers if you want them.
RE: INDX is coming for CoreOne?
Do you already know if it will be possible to buy the 4er INDX kit and the option to expand to 8 afterwards?
Or if you can also say I only need 5 or 6?
With my MMU, for example, I have never used 5 colors at the same time, there were a maximum of 4, but I would just like an option whether you can
expand to 5, 6 or 8
RE: INDX is coming for CoreOne?
Per the Discord discussion with the owners, you can upgrade later, but availability might be spotty at first.
