RE: Update...(Kind of)
A better description of it, is to call it a prime bucket. Purging and priming aren’t the same. AMS single nozzle systems purge the nozzle of an all filament to prevent colour blending. This purge is significant, particularly going from say black to white. However for the indx There is nothing stopping you from skipping the prime. Here it’s to ensure an hard filament “bits” are removed to ensure the print is smooth. This will be tiny in comparison with a purge. Also it presents the need for a prime tower giving you more build volume
In my understanding, the main reason for "priming" is to establish stable filament pressure and flow before moving to the object to be printed. To that end, I am surprised that it can be done over a bucket. I was always under the impression that it needs to be done by depositing a line of filament with the correct thickness, to ensure the pressure situation is the same as during the following print.
(The dual-nozzle Bambu printers all have a bucket/chute, but don't use that for priming during the print. They still want to print a small prime tower for optimum print quality.)
RE: Update...(Kind of)
Might be a silly question but why is there a purge bucket?
I thought the whole idea of indx beyond multi-colour/material printing was to reduce waste, if you are not changing the filament in the nozzle why do you need to purge material?
When printing with a previously idle nozzle you need to establish pressure in the nozzle and remove old material at the nozzle tip. If you have a single nozzle with a single material then one line on the sheet is good enough. If you have 8 nozzles and switch between them, that purged filament has to go somewhere. It’s not as much purge waste because don’t have to completely flush out the nozzle if switching filament types or colors.
RE: Update...(Kind of)
Sounds like an acknowledgement that the indx nozzle either doesn't cool down quickly enough to stop the nozzle leaking or the amount of retraction needed to stop the nozzle leaking is enough to leave gaps in a print after a new nozzle is selected hence a priming action is needed.
Sounds like a major waste of time and filament, if people were expecting indx to change a nozzle and get printing asap they will be disappointed.
Also not a fan of the drip feed approach as it says they are selling prototypes that are escaping early before development is finished, hence the problem, bodge, problem, 'acceptable' bodge drip feed cycle everyone sees which I don't think does a company's reputation any good.

As one of life's great procrastinators myself, I nevertheless recognise that there are times when you have to be decisive. And this is one of those times in my opinion! I'm only posting to check that you realise that the deadline for FE orders is approaching fast - Sunday I believe.
I have yet to order as I continue to procrastinate ...

I'm not sure if you've seen the recent videos, but the amount purged is tiny, and tool swaps take somewhere around 17 seconds currently.
RE: Update...(Kind of)
I do thanks 😂 I’ll use my Saturday to ponder on it. I’ve budgeted for it already so half way there… but haven’t necessarily budgeted for the time hole it will likely end up being

RE:
This is an inherent factor of the tech. All other multi tools do a prime. It’s not really avoidable with the current print head tech

You’re right and they actually aren’t priming into an open box but a little well and then giving over silicone wipers
RE: Update...(Kind of)
mmmh, until we have it installed and running on a large scale of machines the only thing we can judge upon is the videos share also here. Personally I can live really well with what I am seeing and I will go for 8 tools founder edition. If someone thinks that this is too early / still a prototype / etc etc, just wait it out until it is mature and field tested enough for you to buy.
I criticized Prusa (and Bondtech in this case) before for the lack of communication, but what I see being delivered makes me much more confident in the system.
Let's see what arrives, and how it performs.

RE:
It seems the lack of communication was due to the system not being fully ready. You can't tell the customer "this is what is going to be in the box" when you don't know that yourself. I suppose the fence is a case-in-point. I ordered the 8 but still not sure why I need 8 nozzles other than FOMO. I'm currently in the middle of building the 4 spool INBXX so I suppose for now will be using 4 nozzles at a time. An interesting side project would be to somehow use OpenPrintTag to identify the spools and route them automatically to a specific nozzle. A 4x8 demultiplexer?
RE:
That is a reasonable assessment, I chose not to buy the Founders edition because of the lack of clarity on the final design.
The design needs to be far more stable rather than shipping FOA stuff and letting customers suffer/work out the kinks for you which is pretty much what happened with the Core One.

RE: Update...(Kind of)
I respect that position. I am at my 3rd printer with Prusa (the INDX upgrade makes it 3.5? :D) and I've learned that if you want to buy something new from them in the first 6 months of it being released, you will be testing things a lot and probably experiencing some "unexpected behaviour".
If you want stability, you will need to be a late joiner. Then each project varies a lot: I was a relatively early joiner for the C1 but not as early as other that, with their rough starts and comments, paved the way for me to have an absolutlely flawless experience with it.

RE:
I was about 7 months in with the Core One (built it the last week of June 2025). And it took another month to work out the bugs that had already been discovered and solved by the community in the previous 3-6 months. Thankfully there were few hiccups because of that. When I ran into the X motor grounding issue I was able to find the answers here in this forum (which is exactly the same time I joined).
I fully expect the same with the INDX but then I guess that's part of the fun too. I have a second printer so downtime getting the C1 INDX to work won't affect me in the slightest. If it were my only printer and I depended on it (home Etsy store etc) then I would definitely hold-off for 6 months or so.
RE: Update...(Kind of)
I was moments away from buying a core one L the other day… But it had a 4 to 5 week lead time and I had no interest in waiting for that and he gave me time to think better about whether I really wanted to invest in that direction yet.
literally everything you guys said were the things that we're going through my mind.
then bamboo dropped the X2D wedgy on Prusa... and for giggles, I went out and got one of those instead because I could get it right now.
yes, I know the haters out there are not gonna be happy about that… And it is no way an excellent replacement for the INDX system... but in the short term… The next 12 months... I can actually use that and know that it will not have a lot of kinks to iron out. As someone else said, I really don't want to be the R&D for Prusa like I was with my core one.

I think this post touches on some structural problems that Prusa have. They need to get announcement date and shipping date much closer together as the competition are getting 6+ months of sales for their competing products because the Prusa product isn't available and as above giving people thinking time about a purchase because of availability just gives further opportunity to the competition.
I have put an indx upgrade for my core one down on the calendar as a 2026 Xmas present but with a question mark, currently too much 'Heath Robinson' in that last 10% of development and not enough polish.
RE: Update...(Kind of)
I put some money aside… But that is going to be a very expensive printer provided the core one L is actually ready by Christmas with the INDX.
they are starting to sell off the XL by giving deals, but I think the L is where everybody wants to be
RE: Update...(Kind of)
About priming and purging, I think it's unavoidable as part of a robust process. Setting print temperature to minimum will still produce "awesome"-looking benchies but in real life, the most important information from a temperature tower comes when I tear it into little pieces (or ideally, fail at doing so. But that's at the high-temperature end where filament starts to misbehave).
BTW does anybody already have a patent on an upside-down printer? Just pay attention to bed adhesion issues or it'll get "interesting" 🙂

RE: Update...(Kind of)
Quite a few new pictures/videos of INDX floating around on Discord, presumably from RMRRF this weekend.
Nothing groundbreaking... vent auto opening/closing is confirmed which is nice.
