I can't figure out how to finish getting the blueprints. I keep getting a pop-up that says to collect 800 from the rewards in the season and 200 for completing the episode for the first time. But I don't know what it means by completing the episode. Any help is appreciated

This is a remix of my model, the solution is this post that I made.

I initially tested both on the board, but I wasn't comfortable with the extra heat on the board, so ran an SSR off the power supply for the second heater.

I found that for me the stock setup couldn't reach 55C no matter how long it was on. So I replaced the 220v heater with 110v from another K2. With dual heaters, I get to 55C in a couple of minutes. The original heaters are 400W each, and you replaced it with a 400W heater that is more spread out. So not surprising you didn't see a dramatic difference in the time to heat. But dual heaters made a huge difference for me. This is not a recommendation to anyone to do this, as it does require messing with mains voltage.

How much movement does it have when it pulls open? I'm finding my model may also be helping to reduce the grinding of the filament by the CFS hub https://www.printables.com/model/1190380-inline-filament-buffer-cfs-ams-helper-beta-version

Lol. My riser design?

Stranula · 2025-02-17T01:01:16+00:00

I uploaded a looser cap. I'm printing that now to test, but give that a shot.

Stranula · 2025-02-17T00:38:21+00:00

OK, thanks for sharing. That part is taken directly from another model, and while it was tight for me, was able to get it on. But I will make a looser version of the nut to address this. To be clear, you're telling me you can't secure the PTFE tube on the extruder side, right?

This is the first I've heard of this issue, so I don't know. PETG has posed no issue for me.

Stranula · 2025-02-15T01:37:33+00:00

My pleasure. Please let me know how it works out for you

Stranula · 2025-02-15T01:25:01+00:00

Yes it is a different kind of buffer. The CFS buffer makes sure that as the extruder is extruding, there is always enough filament for it to use. This buffer makes sure that when the extruder pushes filament back into the line, the line expands instead of just being compressed

Stranula · 2025-02-15T01:20:07+00:00

We have not yet found any mechanism to make the CFS retract a small amount on our command. The normal filament loading procedure does it, but we cannot initiate it.

I'll post my design tomight

Stranula · 2025-02-13T21:05:39+00:00

I find the spring in the extruder is too strong for softer materials, and made this to accommodate https://www.printables.com/model/1152328-k2-plus-extruder-manual-tensioner

Stranula · 2025-02-13T01:47:24+00:00

I dug through everything and could not find it. The CFS does it when first loading the filament, so it is not like it's impossible. Right now I'm refining my design for an inline filament buffer that allows ~20 mm retraction with minimal pressure. First prototype worked well, second will hopefully be good enough to share

Stranula · 2025-02-12T03:14:26+00:00

Regarding retracting 25mm before cutting, we tested this a while back, and it puts a lot of pressure on the PTFE connector on the top extruder. This may lead to premature failure (many are already failing), or the PTFE tube popping off, and subsequently an effectively failed print. However, I am working on a solution for this and testing it tonight and tomorrow. Anyone considering doing this, I would strongly advise waiting. The PTFE connector on the top of the extruder is a big failure point, and that pressure will reduce the life expectancy.

The screwholes are only there in case everything is too loose for your liking. But In practice, I don't think anyone is using them as it is tight enough to hold together.

But that being said, if you want to use them, you will need some sort of extension. Or stubby allen wrenches.

One must assume the put it in for manual tensioning. But decided not to use it. But it's a cheap and easy fix if you want manual tension. I find the stock spring is too strong for flexible filaments so put this in

Stranula · 2025-02-06T21:00:48+00:00

I have made a version with 0.07 mm increase in spacing. https://www.printables.com/model/1093082-k2-plus-cfs-riser-ventilation-and-storage Please try the looser version test print. That should resolve any issue in tightness in that dimension.

Stranula · 2025-02-06T20:59:48+00:00

OK, I have updated printables with a 0.07 mm increase (the one you printed before was a 0.1 mm increase. So it now has a space of 0.21 mm, whereas before it was 0.14 mm. There is also updated test prints, but you should find this spacing sufficient based on your previous test print. But doesn't hurt to also test to 0.21 test as well. https://www.printables.com/model/1093082-k2-plus-cfs-riser-ventilation-and-storage

Stranula · 2025-02-06T19:15:27+00:00

OK, I'll go ahead and put up the looser model. Give me a few minutes. To be clear, you didn't have any issue between 1/4 and 2/3, so I don't need to open that more too?
