RE: Filtration Kit.....
Yes, there are people receiving these now.
RE: Filtration Kit.....
Not shipped for me, another day, another date creep for expect to ship window, Ordered day 1.
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.......
I like the idea of using magnets. But, since the threaded screw holes are already there in the sheet metal, maybe fill the sheet metal holes with short machine screws and use the heads of the screws as registration bumps to ensure proper placement.

RE: Filtration Kit.....
Just installed mine
RE: Filtration Kit.....
It doesn't make too much noise, much less than the case fans, but that said it seems to replace the functionality of the case fans entirely even when printing PLA and PETG which is a bit disappointing as it doesn't do nearly as good a job cooling and I live somewhere very hot.
RE: Filtration Kit.....
Nope, just the blower from the filtration unit. You can run them manually but I don't know if that does anything detrimental to the filter unit.
RE: Filtration Kit.....
So the case fans no longer run at all when the filtration fan is connected?
Nope, from the release notes of the firmware on GitHub, they say:
Note: When enabled, the Advanced Filtration System also takes over chamber temperature control and disables the cooling fans (with the exception of critical overheat situations).

I can't think of a reason why it would be detrimental. But I hope prusa add an option to set a chamber fan speed limit as a "support" option for the filtration fan so that it cools additionally. I don't want to set the chamber fans manually all the time. Maybe automatically setting them to 10-20% would not add to much noise but help with the cooling of the chamber.
But it is good to hear, that the blower fan is quieter than the chamber fans. Because I think they are annoyingly loud.
RE: Filtration Kit.....
Would have been nice if they had mentioned in the build instructions when to do the steps for the camera and filtration systems. So you don't have to take things apart again to install them. I added a comment in the conversion manual at the point where I think it would be best to do it.
RE:
I'm no longer really sure whether I want the filter system at its current state. It doesn't seem 100% well planned to me.

Yeh I've kinda gone off the idea too.......

Interesting, so does this mean that if the chamber temperature is good that the filtration is not running?
This maybe changes my mind about recirculating. Here are my thoughts.
- If the chamber temperature is good, the filtration fan doesn't run.
- This maintains chamber temperature which is what I was worried about.
- The toxic particulates stay inside the printer enclosure since the fan is not running .
- If the chamber temperature gets too high the Filtration will turn on and will filter any exhausted air and allow cool air to come into the enclosure.
- At the end of the print the Filtration fan runs for a specified duration to clear the chamber of any harmful particulates.
This seems logical to me if this is the way it works. I was initially thinking the filtration would constantly run, but with what I've laid out above that's not necessary.
Can you verify if this is how it works?
RE: Filtration Kit.....
Yeah I'm mostly just disappointed as to the lack of explanation as to how it functions. I thought there'd be more details closer to shipping time.
But they just tell you how to install it and that's it.
I do still need it here and there because of where my printer is, but something a bit more easily removable or modular would have been better if it's going to be a full replacement for the case fans.

Can you run some test prints and verify how it works for us?

With volatiles yeah, then it runs to vent after the print.
But my issue is it's also used for chamber temp when printing PLA and PETG where a lower chamber temp is required and I live somewhere very very hot so it wasn't strong enough to cool the chamber.

I printed some ASA and PC blend yesterday. I'm too paranoid to print styrenes without it but I printed PC blend before without and I guess there was less smell and my air monitor didn't pick up significant VOCs.
As for PLA/PETG which require chamber cooling and not heating it's getting to a minimum that's about 5-10C higher than what i was getting with the chamber fans.
RE: Filtration Kit.....
Can you manually turn on the chamber fans?

Yes
RE: Filtration Kit.....
What temperatures are you getting to when printing pla? Unless you're printing super steep overhangs in my experience up to 35 C doesn't hurt anything with pla. I've been as high as 45 C for petg without issues.
