Anyone tried these fans before? http://www.robotdigg.com/product/194/5015-12V-Blower-Fan I can't tell if it's pwm controlled (it does say for cooling prints, so probably?) but it is 12 V and appropriately sized so it can be connected to the V2 board. I'm not sure about the performance, though.

Ahhh 5V: not really compatible with the UM2 board, is it? I would need four of them to get to the 19 - 24V. I guess I'll have to get some 12 V ones from somewhere else for my UMO+.

Woah, that's a nice design! Now I'm tempted to make a UMO+ E3D V6 mount with two of those blowers. Combined with neotko's awesome lrobertl feeder with the bondtech gears, my machine will be unstoppable

What fans does the UM3 use? It just says quieter and more powerful, but what are the specs?

Unfortunate I was thinking along the lines of some new fans, belts, etc.

I'm just wondering, will there ever be a spare parts kit for the UM3, like the maintenance kit for the UM2+? It might be worth having to hack my UMO+......

Thank you for saving my thread

I'm sorry if I missed the link, but do you have your files anywhere, for free or for sale? I see a lot of things that say "based on foehnsturm's design", but not your own...... You name the price and I'll pay for this thing

Socket? Like the blue "socks"? I'm not sure if that would help, because all they say about it is that it helps retain heat so better bridging and a more stable temp., and any leaked material is blocked. And yeah, dual extrusion just seems to be so much trouble...... I like your magnetic head changer, but I really want to use the E3D V6 and I don't want to sacrifice any build volume, so...... Yeah. You kind of get where I am. Caught between soluble supports, affordability, and ease of use.

Okay never mind. I just remembered that the E3D V6 has the embedded bowden coupling that takes a 4mm OD tube, so yeah, I'll probably need to modify the feeder. Also, I know this is kind of off topic, but do you think that the y-splitter is worth it? The video they have shows a bit of color contamination, so I'm kind of worried that it might be more trouble than it's worth.

That is impressive amazing stunning jaw-dropping impeccable.

Woah, that is a nice store! I need to spend some time exploring I do have one issue with that though: I want to use this y-splitter: http://www.thingiverse.com/thing:1680034 but it needs PC4-M5 fittings, and I'm too lazy to modify anything, so I'm hoping to find something like a PC6-M5, which probably doesn't exist. I did find this: http://www.charlies3dt.com/en/product/straight-threaded-push-fit-connectors-1 but it says its a 1/4" thread, and I just get lost when things are put in imperial...... Would that work? Or will I need to start modifying models?

6-2mm? Wow. Where in the world did u get that? So basically the one that the UMO+ had originally would fit if I get my hands on a 6-2mm tube?

Would this one from E3D work? http://e3d-online.com/Mechanical/Bowden/Threaded-Bowden-Coupling-1.75mm-Filament

Great design, and amazing writeup! Now I'm convinced to get two of these and hook them up to a y-splitter leading into an E3D V6. I just have a quick question, though: what are the dimensions of the bowden coupling? I don't know where to get one......

I don't have any spares, but if you want something with solid performance while fitting a tight budget, consider this: https://ultimaker.com/en/community/22080-fatiroberti-feeder-for-bondtech-dualdrive-175mm-cheap-kit Most of the parts can be printed, so all you will need to buy is a tube (cheap and lightweight for shipping) and the awesome bondtech drive gears (bondtech is just incredible).

The moisture problem is kind of true for all filaments, some just absorb moisture faster. PVA and nylon are two filaments that absorb moisture like crazy.

Hey, does anyone else find cura 2.3's retraction limit of 45 mm/s annoying? My arai the dragon had mini spikes on its wings because of stringing.

I really would like to see a UM3 in action...... Thinking about paying my local reseller a visit to see if they have one on display

There's a new material called "Scalmalloy", invented by Airbus (they then founded a separate company to make it available to the public). It has pretty much the same mechanical properties as Al7075 (on their website they compare it to titanium, which is stupid Marketing blahzay). I had a part printed there 6 months ago, it's beautiful, even the price tag is OK (twice the price of printing the rather low-tech AlSi10Mg material). r Too bad we don't have anything that strong for FFF/FDM yet...... What would you say is the strongest filament right now? PC Max?

No, not a dampening system. It's needed for the bed levelling. The nozzle actually depresses the plate slightly during levelling. Oh okay, less impressive, but still nice Is it built into the aluminum plate?

suppose so.. you will have to take in mind that the back of the bed is now spring loaded, so it's flexible if that makes sense? The back spring-loaded? I'm assuming that's not the bedleveling spring, right? How is it spring loaded? O Do you mean that the bed itself is flexible and is held tight by the tension of springs? Or something else? yes, the back end of the plate can flex up and down Was that a deliberate design? Does it affect the top surface of the bed and cause it to resonate or move around? i think it is :)it doesn't impact any quality, works like a charm. Woah...... So like a dampening system? I'm impressed. I need to add this to my 7 Wonders of the (Desktop) 3D Printing World.
