I treated myself to an H2C for Christmas, and just got around to setting it up yesterday. The sucker weighs quite a bit, so I had to remember to "lift with your legs", but really it should be a 2 person lift to be safe. Setup took a while to run though the calibrations, but so far it has been running pretty well. I've not run any multicolor prints yet, but having a stash of ready to go nozzles in different sizes is really cool (even for single color). But one thing I noted is that, despite having a pretty good sized filter, I can still smell the melted plastic when it's running certain materials (like wood PLA). Based on the pics I've seen, it looks like the fliter either moves up and down, or there may be a door that blocks the bypass air. I suspect the issue is that air can bypass the filter, due to the design of the exhaust system which has to do double duty as a filtered exhaust and recirculating filter (when running the heater). I'd like to find a video which shows how the system works in detail (if I do, I will post a link). It's a shame though, since it has a really big HEPA filter, with carbon, and the printer is much better sealed than the X1C (unfortunately it seems it's not as well sealed in the exhaust path through the filter).
The H2C is just a tad big for my current enclosure, (though I may still cram it in there), so I thought about bringing back an old (stalled) project which I never felt was tested enough to release. It's an inline booster fan, designed to draw out fumes from the X1C (or any enclosed printer with the right adapter). It should work with the H2C, and help pull the fumes out the back of the printer, where the exhaust is vented. It may also help remove any air that slips by during the recirculation filtering too.
I was gonna work up an exhuast adapter, but found a really cool exhaust duct by Clough42 on MakerWorld, which is designed for the H2 series. He kindly provided the STEP, so I reworked it just a bit to fit my existing hose couplers, and increased the standoff distance by 10mm to clear the poop chute (since it will bend to the left side of the printer). I'm printing the adapter currently, and will need to order some screws to mount it. The plan is to run a short hose from the adapter, over to an inline booster fan, and then duct it from there, out an unused doggie door. Once I get the fume situation settled, at least for a while, I can get down to really using the H2C. I also plan to (finally) release the remixed duct, along with my booster fan design, the hose couplers, and doggie door adapter, once I've got everyting running and tested (if it works well enough). I've got a spares case update planned for it, and some other projects, where it should really shine with it's multimaterial capability.
