The UM2C Air Manager is connected in the same way as the S5 version, so no separate power supply and on/off switch. The fan is controlled by the printer itself.
It doesn't fit the S3 and due to the missing port in the UM2(+) you cannot use it there without making your own power supply and control logic.
I can measure it later if the Air Manager would fit physically the UM2(+) - I don't know it out of my head.
Kind of seems like the S3 has become the neglected orphan of the lineup? No material station, no air manager -- it's more expensive and higher end than the UM2C but still comes with compromises in comparison, and it's almost in the same league as the S5, but not really.

it's really hard to tell what is happening here, you seem to be saying the silcom covers are failing some how ?, this doesn't make a lot of sense. I cannot see how the one in the photo managed to split.
I have been using the same cover with all cores, including a CC for over a year and it's still fine. To get them to fit correctly you have to persevere and hook each corner and flap in the appropriate groove, it should then sit flat on the bottom of the print head failure to do so will mean they get caught, i assume this is what is happening.
Fair enough, thanks Link.
It hasn't happened since I applied the last one. I'll keep an eye on it. -
Any chance of an Air Manager for the S3 please?

I recently started getting nozzle cover failures during prints. It's hard to pinpoint when it started happening. It possibly coincided with switching to the 0.6mm Ruby CC Core, and then the 0.8mm AA Core.
Attached is a photo of actually one of the less dramatic examples. In this case the print completed successfully.
In the other cases, a loose bed seems to have contributed to the problem. I have since tightened the 'clamps' on the bed and conducted manually leveling (because auto leveling was subsequently failing). Attached example of failed print due to plate movement.
Can anyone offer advice on this issue please? I had a decent supply of nozzle covers and now I'm down to one, only after a few weeks of printing with the new Cores.
I am following the nozzle cover replacement procedure to the letter, and they fit snugly prior to these failures.
For completeness, here are two photos of the print cores (after removing the failed nozzle cover):
Thanks!

Thanks for the reply Smithy, appreciate it

Hi all,
I'm trying to print with standard Ultimaker PLA on an AA 0.8mm core. I'm using the built-in Fast 0.2mm printing profile in Cura.
As with all new nozzle sizes and materials, I printed a temperature tower. This is how it came out:
This is how this print comes out with a different filament (although with the AA 0.4mm Core):
Looking at the online documentation, it suggests 200-210C and higher temperature for the 0.8mm nozzle. However, looking at the temperature tower, it seems like 190C or 195C came out best.
These are my Cura settings:
Any advice please?
Thanks!

It worked for me with the S3 when Colorfabb updated their profiles on the marketplace.

At least each one is unique! 🙂 You could sell them as art......to pay for the filament. 😉
Have you tried using supports, or are you avoiding that in case it impacts on the final quality? Unfortunately any supports that reach to the top are going to add a lot of material and time.
Hehe, that'd be nice!
I haven't tried with supports yet. I guess I'll add it to the list! Thanks for the suggestion -
Attached is a rather sad effort that was a result of printing a thinner version of the model. It still seems to be printing too many layers, and no amount of IPA smoothing helps.
I used the PolySher (image attached) for IPA smoothing. It's a pretty impressive device. Going to try it with a regular model today to give it a proper test.

Hey donogh, you might not have gotten your desired result yet, but I love your 'mistakes'
Thanks AddMan! 🙂
The effort is continuing! Last night I started experimenting with a source model with thinner walls, and I'm now using the PolySher from Polymaker to do the IPA coating. I'm also waiting on the 0.8mm Print Core, which should work better.
It's a challenge for sure! I'll post my newest test later 🙂

I don't think the reason is the temperature itself, but that the 240C part is the lowest one. So in this special model the fans are cooling probably better at the bottom near the glass, cool air get reflected, than on the top.
But I am just guessing.
That makes sense, thanks Smithy, good insight!

Thank you Torgeir for the advice, really appreciate it.
I gave it another trying with 0.4mm layer height and adaptive layers. Please see below.
I guess I will need to try turning off spiralized mode, and manually playing with the wall thicknesses.
I did manage to print it fine before but it ended up with very thick walls, which meant it was impossible to achieve transparency with IPA (second attachment).
It seems the solution is somewhere between the two!
Thanks again!

Hey all,
I'm trying to print a transparent 'helmet' for a model. I've attached a 3mf.
With transparent PolySmooth, you can print it thinly and then spray with IPA to increase the transparency (by smoothing the layers).
Attached are my two attempts. The first one was going perfectly until it got near the top. It seems the curvature is just a little too steep for vase mode. The image attached is with a couple of layers of IPA already applied (to illustrate the transparent effect I'm trying to achieve).
I then tried printing it upside down, but it seems it couldn't adhere to the first couple of layers, and I stopped it shortly after (you can see there is a spiral of loose filament on top of the initial layers).
Any idea of settings that might help, please?
I'm printing with a 0.4mm AA core on an Ultimaker S3. Attached images of all my settings.
Only thing I can think of is maybe specifying more top layers?
Thanks!

Anyone have any thoughts on how I might improve this please? It's using the default settings for the Cura profile for Color on Demand, plus the change on Z extension, starting at 240C and finishing at 190C. (3mf attached.)
The recommended temperature is 210C. 200C seems a lot better, but the right edge/ridge is only correct at 240C.
Anything else I could try, please?

The plugin got a update today, so maybe its fixed for you now on the 3S, i know it worked fine on the s5
Yep, thanks Carla. I've been in touch with colorFabb support, Gijs has been super helpful. He just informed me of the same 🙂

Yes, that might be the key. I was btw. referring to the material selection on the printer but looked it up on a S5.
Gotcha, thanks! I reached out to colorFabb support. Maybe they can update the plugin.
-
Maybe this has something to do with it:

The Ultimaker S3 isn't listed as supported?

The CFF matrials are the generic Carbon Fiber Filled materials.
Look out for "Color on Demand Generic". It's probably called like this.
Btw. Is there a special reason why you put the PVA into print core 1 and the main material into printcore 2? While it is possible and should theoretically give the same result, you probably get slightly better results the other way round as this is what people usually test materials profiles with.
Good to know re CFF, thanks!
Unfortunately, there is nothing in the list prefixed with 'Color on Demand'. Attached shows the material plugin in Cura. It shows fine in Cura, just not on the list of materials on the printer (checked and double-checked!).
For now I set it to Generic PLA, and used the settings listed under Print Settings for Color on Demand in the Manage Materials menu. I guess that should work okay.
No particular reason why I have them swapped around. I think I was switching between PVA and a second PLA material, and it was somehow more convenient to leave the PLA on printcore 2. I'll swap them back around, thank you for the advice!

I've added the ColorFabb materials from the marketplace, and it's apparently sent the materials to the printer (S3). However, it does not appear in the list of materials I can select -- there are other ColorFabb materials, none of which are supported with the AA print core.
When I manually override the material to colorFabb Color on Demand in Cura, the profile menu switches to 'Not supported'.
Attaching screenshots showing the 'CFF' materials on the printer, and the not supported message in Cura. (Newest S3 firmware and latest version of Cura.)
Am I missing something please?

Very cool! One more thing for the 3D printing shopping list 😆

Thank you for the detailed reply Carla, much appreciated. I'll check out UPSs in that case. The S3 uses 350W, will probably go with 1000va anyway!

Don't get me wrong, Smithy, I think the lineup is awesome. I wouldn't give up the print cores or the dual extrusion on the S3. It's just surprising that it doesn't even have an Air Manager, and that's been prioritised for the UM2C over the S3.
