Update on the X1C Riser (Version 2)

11/14/2024

It's been a while since I started working on a 2nd version of the X1C/P1S riser, and unfortunately that project sort'a stalled out when other smaller things popped up. Today however I got some time and worked on the design a bit more. It was actually a pretty extensive re-working of several parts of the design, but I think it will be worth it. The biggest changes are the addition of WAGO 221-412 connectors, which should remove the need for soldering. The WAGO's will go into a printed holder, which will then go into the riser. I need to see if the holder can be glued in place (that is if the WAGO's can be removed if I glue the holder in place). I have just one small problem though, which is a complete lack of WAGO 221-412 connectors. I'm gonna pick some up to test.

The 2nd change is a modification to the TPU top gasket, which should make printing it a bit easier. The new design will be a bit thicker where the overhang is, and I'm planning possibly more tweaks to it. That will take more time and material though, and I'm pretty low on TPU, so it will be a bit.

Update 12/10/2024: This is still gonna happen, but right now I'm busy with other projects. I have a few unrealized but definitely possible additions I want to add to this design, but they will probably happen at the beginning of next year when the holiday craziness is over.

Hey, I appreciate all the work you've done on this riser design. Your design seems like one of best, based on the following criteria:

1) Impact to overall enclosure height
2) Not compromising chamber seal
3) Ease of use of ventilation
4) Lighting provisions

Have you considered adding a port on the back where the filament can pass through at a higher angle, to reduce the angle that the filament has to go through?

I've been looking through all the available risers and while yours seems to have the best overall, a couple newer designs are optimized for top feeding stiff, carbon-fiber reinforced filaments. I still need to figure how how all this stuff interacts with the filament buffer (just finished printing two Python AMSes and I'm working on hooking them up this week) but having that last feature would potentially be a killer add-on.

Also on the wishlist: finding a way to reduce the height of the design so that the H2D doesn't exceed the available height of most shelving systems. According to the rumors it's 626mm (24.65") tall compared to 457mm (17.99") of the P1S/X1C, so once you add a 1.125" decoupler underneath and the 1.25" riser on top it's 27" tall.

Finally an idea for lower maintenance ventilation: to prevent ASA fumes from compromising my house, I have both P1Ses hooked up to an AC Infinity 4" ventilation system with booster fan and flapper valve that is T'ed into the dryer ducting. The big fan can really pull a vacuum on both printers. I was thinking, if one of the risers was a top-hinged flapper and opened inward when suction was pulled, you could automatically ventilate the printers without needing to manually open and close the vents. All you'd need is a way to lock the flapper so that when you're not intending to cool down the chamber the magnetic flapper door can't get pulled open.

Apologies I did not see this comment earlier, and thanks for the kind words!

I've not looked at adding a filament pass through port, but it's in interesting idea, and I will have a look to see what is involved there.

I've not tried the Python AMS, and just deal with the small issues of the stock AMS, which works pretty well about 90% of the time. I'm not sure how top feeding would work with the glass, but I may be misunderstanding. I just remove the glass when on the rare times I need to top feed, but the printer is in an enclosure so I can feed from the top of the enclosure into the printer.

The H2D is on my wishlist too :D I was not aware of those dimensions though, but if I get one, this design may be adapted for it too (unless it has good lighting already).

Having a flapper integrated with the design seems possible, but it's a very application specific thing (not many people would use it I think). Flappers can also be tricky to design to work automatically though, since if they are light enough to open automatically, they may not seal well when closed (takes some trial and error). Manual flappers will seal better, but then it takes away part of the reason for it. I will need to think about that, but I don't see it as part of the initial release of the design at least.

I've been a bit behind on things for the past month, but this is on the to-do whiteboard for projects to get moving on.
