RE: Filtration Kit.....
Yea, not getting it either. The fan and media appear to be the same ones for the normal enclosure, so isn't just sheet metal?
The filtration system is as simple as it comes. A fan with some filter media. Why it is being held up and delayed for months is beyond me. I have no idea!
I think it's smaller than on the normal enclosure based on the size in the pictures. I guess we won't know for sure until someone receives it.
RE:
Did anyone receive a shipping notification yet? I have an order date of 1/22 and expected shipping of 5/10-5/16, but its meaningless since it gets pushed every day. Would be nice to know if they have even begun shipping these

RE: Filtration Kit.....
And, yet, there doesn't appear to be any instructions that I can find on the Prusa3D site for installing it. I assume it's expected to plug into "Fan3" on the extension board, but we all know the saying about assuming...

Never mind, I accidentally stumbled on the instructions in the CORE One printer maintenance here.

RE: Filtration Kit.....
"Now it shows May 9-15, no shipping notice yet."
Yesterday it showed May 10-16, Today, May 14, it shows May 11-17. I have nothing else in my order that is out of stock. At least they are updating the shipping estimate every day.
RE: Filtration Kit.....
It seems to move at midnight GMT every day it isn't in a prep state. Sliding a day at a time, I'm guessing I'll see a June date before it ships.
RE:
Maybe Prusa have realized in the meantime that the filtration concept does not work well? The filaments with nasty emissions are also the ones which require a high chamber temperature, hence no airflow out of the chamber.
So they might either be searching for a workable airflow compromise in firmware, or may be in the process of changing the filter unit to a recirculating design. They have already changed the design once since they started taking orders (compared to the original photos on the shop site). But I'm just speculating here of course.

I'm going to redesign it when I get it to recirculate. I wish they had released cad files for this, but I imagine they won't since it's appears to be sheet metal and they haven't released any cad for sheet metal stuff that I'm aware of. So I'll be using my calipers and reverse engineering it.
RE: Filtration Kit.....
Hello, I will finally receive my KIT tomorrow and it contains the bloody HEPA Filtration KIT 😊
It caused two months of delay on my order created 2 minutes after the opening. 😡
RE: Filtration Kit.....
I know it states on the website, that items may hold up your order but for Christ's sake!
Don't offer a filtration option on release and then have it hold your order for potentially months because, it's either not ready or the manufacturer of it is having issues with demand.
I know I keep banging the drum but how do people tolerate this sort of business practice?
Scott
It all depends. In my case I have enough printing capacity and am not in dire need of the printer. I figured some of the bugs would be worked out by the time it arrived.
Admittedly I am starting to lose a little patience. I am a day 1 order back in November. I recently inquired with support and they said my order is priority and will ship soon. I asked about switching to a kit and how that'll affect my order, so we'll see. I had originally anticipated that the rollout of the kits would have taken longer, but they actually did really well imo of sticking to the schedule.
I guess to answer your question directly nobody is being forced to keep their order. Any person could cancel their order at any time no questions asked. You don't even have to contact support, just go to your order and cancel it.
The part I am confused about is why so many people who are unhappy with Prusa continue to hang around and complain about it. If I despised Prusa and their business practices, I surely wouldn't waste my time hanging out on a Prusa forum. I guess I have more important things to do.
I get your point, people can cancel, it's their perogative, yet people seem to hang on and on, as it seems Prusa can do no wrong for some.
They have surprised me with an earlier than scheduled delivery though, which was nice, but I'm guessing it was because I didn't see me getting my printer this side of June with the filtration, so cancelled it, which may of brought it forward.
I guess, if you're in a position such as your own, that you don't need the printer, It's fine. Likewise, I held out for mine, as I don't need it either, it's potentially the start of a hobby for me and something to involves the kids with, so no rush.
I guess you're right though, I could just not talk about it, cancel my order and get on with my day, but if I'm unhappy about something, as others also are, I speak up. If you feel that's a waste of time, then I champion your decision to crack on with waiting. I guess complacency is in the eye of the beholder. I'm sure the important things you need to do are more important than standing up and talking about things that Prusa could do better for customers? But you seem quite humble about it......
I don't despise Prusa, or their business practices, how you got to that conclusion is beyond me. Yes, I've been vocal about certain aspects of the way Prusa handle orders, but I certainly wouldn't put me in the 'hate' camp, I'm merely questioning them, it is an open forum after all?!
Hand wringing aside, there are things that Prusa do, that aren't considered regular, especially where pre-orders are concerned. To like it or lump it, isn't what newer customers like myself want to hear from established members of the community, and only bolsters the preconceptions of said community.
I heard about the hard-core Prusa collective before coming here and I was a little apprehensive about the community not taking criticism of the brand lightly. I have seen people defend them, justly and sometimes, IMO, unjustly, but that's a matter of opinion.
What most can agree on, as many have aired, if your hard-core Prusa or not, is that there are improvements to be made within certain aspects of their business, which are the norm for many companies across the world. They've been doing it long enough to evolve for the better.
I really like the Prusa brand and the ethos of upgradeable machines is what attracted me in the first place, plus they look cool as fcuk 😅
But, unless they up their game, they may begin to struggle to keep newer customers such as me interested, unless I learn to like it or lump it, which I don't see happening anytime soon in spite of how may Haribos Gummy bears come with a printer 😉
Scott
Great response Scott. I appreciate a civil discussion and you have good points.
I didn't mean to point it at you in particular, and I apologize that I made it sound that way. It just triggered my annoyance with the forum lately with some users, not you, that seem to be only on the forum to complain on many different threads. It's made me consider not browsing them anymore.
I'm here because I enjoy helping others and learning stuff myself. I'm always impressed with some of the stuff that people come up with and the useful tips/ solutions to issues that people have. I don't mind anyone expressing their opinion, even a negative one, but when its the same thing over and over again it just gets old.
I also agree with you on the Filtration system. It's getting a little old how long it's taking. They would be better off saying they won't have it for 6 months, and then shipping early than Vice Versa.
I also ordered a bunch of other things that I needed along with the printer to save on some shipping, but apparently some of that stuff has held up the order as well. For example PCCF. I bought a few rolls when it was in stock and added it to my order. Recently support told me that it was the PCCF holding the order up. I'm not sure how that's possible, shouldn't they have allocated it to my order when I bought it? So there's definitely room for improvement.
Exactly.
You make valid points too, it's all cool from my end as I know how these places can be. I've been on my fair share of mtb, airgun and car forums to know some things can get too much ☺️
The forum did become a bit of a quagmire of complaints of varying degrees, maybe because it's the only place to vent if people don't get the resolution they seek from support. The waiting game for the kits was a bit much, as frustration and unknowns bred anxiety which some express here, which is fine, and it wasn't without cause, but I digress.
Anyway we're over that now, it's been a long road with some light at the end of the tunnel and it's all about the light right now 😅 I'm also here to learn, even if I don't post much, as I'm picking up what I can and will answer the odd question if I've covered it through scouring the forum every other night or in my dinner hour, but generally people beat me to it, and that's so cool to see everyone offering/getting help where they can, that's what it's all about 😍
To have orders be delayed by quite a margin because they can't manufacture PCCF quick enough, or if the filtration supplier is behind, should be a discretionary decision made by Prusa, but not at the cost of the customer. Anyway, let's not get bogged down with "'hhhhhooo killed hhoooo" 😉
I'm hoping your order is on its way to you soon and you can fettle it to get everything to you in due time, we all know the wait is a testing time, but I'm hoping the outcome is rosy for us all.

Does seem a very simple design, maybe the fans, electronics are holding it up?

That's crazy.
How someone has also managed to take delivery of the filtration that has actually held up other people's earlier batch orders, but no printer really is something else.

Ssounds like a good plan, it looks a simple design. I'm no electronics expert either, but I would of thought it would be fairly simple to do?
As far as I see it though, the enclosure isn't air tight or close to it anyway, so you'd always have some seepage of VOC anyways right? Would the trick be to force some of the inside atmosphere through the filter with maybe a slow fan rotation, just enough to create a pressure difference between inside and out?
I'm just spite balling ideas at this point, I have no idea of fluid dynamics, as you can probably tell 😅

Yes, I also think you would want a bit of "one-way" airflow which leaves the enclosure through the filter, and is offset by some slow air intake through the various slots in the enclosure. That should should minimize the leakage of VOCs and particles through these openings.
You could easily achieve that by making the external duct which recirculates the air back into the enclosure deliberately "leaky": Push air out of the enclosure, through a filter, via the fan. Then guide most of the filtered air back into the enclosure, but not all of it -- let a fraction escape to the outside via an opening in the duct. Looking at the airflow balance of the enclosure, this "lost" air will be compensated for by air that gets sucked in through the various small openings.
RE: Filtration Kit.....
I'll have to play with the design but my current printers aren't airtight either and recirculating shouldn't add any positive pressure to the inside, so it shouldn't really make it leak anymore then it would with no circulation.
I don't print a lot of ASA, but when I have, I haven't noticed any smells in the room so I think the HEPA/carbon filter is doing a relatively good job.
The only downfall I can see with my idea is the fact that you'll no longer be able to pull cool air in for printing things like pla due to the recirculating nature. However I don't do that on my existing enclosures either. I'm thinking of maybe designing a flap that you can open or close so that when you're printing pla you can open it up and allow it to vent into the room instead of recirculating. I don't personally need it because my printer is in a temperature controlled area and my current enclosures never get hot enough to be a problem for PLA.
RE: Filtration Kit.....
Rather than screw the filter into the back, attach it with magnets. That way you can easily pull it off and remove it when printing materials that do not need it.......

And what materials would those be? 😉
I'm hoping to be able to filter the air for everything I print, not just the ones I can smell. Recirculating air filtration with an exhausting option as mentioned above would be ideal, and I expect designs will pop up for that soon. It's just too bad that Prusa doesn't seem to be making that the factory option.
