so he is lying to you that's for sure the nozzle wouldn't block it after an hour. first of all, if the price is right, buy it. nothing much can go wrong with these printers. just look for exterior damage.. how many printing hour does it have? below 2000 basically means it is as good as new.. look at any exterior damage , are there cracks? are the belts ok? they should be tight. move the head around, does it move around smoothly? if not, put a little bit of sewing machine oil on it (take that with you!) and move the head again. then i would say a used UM2 is worth between 800 and 1000 euros depends on the hours it has ran.. the problem he is describing is the PTFE piece.. that will clog up your prints.. just buy the thing as cheap as possible, buy the upgrade kit for 400, it will have a new feeder, new head assembly and this will solve all those issues.. that way you have a basically almost brand new um2+ for about 1200 to 1400 euros.

yes, it's awesome!

so what kind of printer are you using? your top layers seem fine btw..

can you post your slicer settings? how many top layers have you selected? this looks like either under extrusion or not enough top layers.

little clarification, the 2200/2300 gram spools that you can buy don't fit. the spoolholder is moved down just a few CM as compared to the UM2(+) and the spoolholder hits the ground. the rest seemed to fit so I support a few 1 or 2 CM high supports would fix this issue..

I've thrown a multitude of materials through my core, from NGEN to XT to PLA back to XT, back to PLA again.. without a real " nozzle flush" and definately without a cold pull.. all with excellent results..

yeah, I'll get an additional one or more.. love the printer.. sure, some things could be better, I agree witht he BondTech argument, but all the other things.. it's not necessarily better then my UM2+ printers, but it's more aligned to how I use them..

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.

Just did a quick rough measurement between the 3 and the 2 and it seems to me the 3 bed will just fit... THANK YOU. It's great to have someone who has both to measure it out I'm assuming that the heated bed has not changed. Is that correct? while UltiArjan is still asleep, i can help you out there there are some small changes there, the Z stage has changed completely, but the temperature range and the glass plate have remained the same. I do believe it reaches the temperature a bit quicker as compared to the UM2 and UM2+ but that might just be my imagination.

so i'll reply as well.. the whole UM2 and dual extrusion discussion is pretty much dead. yes it was promised for the UM2, no it was never promised for the UM2+ and if you were expecting it for the UM2+ that is not something Ultimaker had anything to do with. sorry if that sounds harsh, but they have been very clear since the beginning of the UM2+ that that device would not do dual extrusion. if you were expecting it that;s not something you can blame on them.. yes it was promised for the UM2 but they made a very good point about why it couldn't be done. and if you look critically at the UM3 (which i've been testing for the past few weeks) it is very obvious why it could not be done this way for the UM2. that being said, there's also the point of the UM2+ versus the UM3. the UM2+ is the improved version of the UM2. a lot of community feedback and testing went into that. the UM3 has, in my opinion, nothing to do with the UM2(+). it has a very different target audience, and a very different use case. the fact that some people are already saying they now need to replace all of their specialized nozzles with cores and how that is super expensive quite frankly just don't get it. this machine is not meant to be tinkered with all the time. this machine is a workhorse. you buy it because you need a lot of very reliable prints. done. if something's clogged or broken, you want to replace it on the spot with minimal downtime. if you put material in it, it needs to be back up and running ASAP. if you read the description of the UM3 carefully, you can see their target audience is universities, prosumers, prototyping environments. it's simply not the tinkerers.. if you want a lot of swappable nozzles, different feeders, and your own way of doing things, you need an UM2+. if you run them 24/7 and need a very reliable consistent printing experience, you need an UM3. they are simply very different machines. I run one of the, if not the largest 3d hubs of the benelux. i run 4 UM2+ printers 24/7 and I could not be more excited for the UM3. your comparison for 7 euros for a nozzle versus 100 euros is simply wrong. i've calculated maintenance cost for my UM2+ printers at around 125 euros per 500 hours, and I expect the print cores to last for about the same time. once the performance starts dropping, i'll throw out the core and get a new one. no more taking the head apart, risking damaging any of the axes, realigning the build plate etc. etc. you have to compare apples to apples.. if i run abbrasive filament through the head, i think i run a greater risk of damaging the feeder then the nozzle to be honest. but even if i damage the nozzle, I'll just charge more for abbrasive filament. it's just a business calculation. I can actually see my prices dropping with the UM3 instead of going up.. that being said, if I'm focussed on building great models, like valcrow or any of the other great artists that we have on this forum, the UM3 would not interest me at all since it lacks the flexibility I would need. I would love the Um2+ in that case.. anyway, that's my rant.. you gotta put things into perspective. the UM3 is not a successor to the Um2+. it's a new device for a new market. a market currently dominated by the 10K+ printers.. and I think the UM3 can easily hold it;'s own.

i can only second that.. been testing the Um3 for a while now and i run a 24/7 operation based on UM2s.. the Um3 is a different beast altogether, it's not better or worse then the Um2, it's different... and I love the new machine!

noooooooooooo! you are correct.. i don't know how i made that mistake. i'll go site in a corner and be ashamed.

?? it was stated that at 17:00 everyone would know.. however, that translates to 18:00 in the UK

There are launch parties in different countries, but I am not sure in which ones. At least I know there is one in Spain, The Netherlands, United States, Canada... I am sure @sanvervg know more about it. The only thing I am sure about is that tomorrow at 17:00 no matter where you live, you will know how the new Ultimaker looks like. poor people in the UK.. they'll have to wait till 18:00

good to see i'm not the only one hit with the double reply bug. secondly, Back to the drawing board my dead watson!

did you uninstall any previous 2.X versions of cura?

didn't you see the latest render leaked? 3D printing will be great again

if you say so

I'm sure it'll be something small and smart

Could be that I'm just overlooking something, but isn't that just the default way of doing it? (eg the same way the UMO Dual extrusion kit does it?) in the video (after a while) there is a small mechanism that somehow lifts the head about 1 or 2 mm and lowers the other one. it's also the defacto standard way of doing this with 2 nozzles in a static head.. so not that surprising.

i think that's a very healthy approach i always get very confused when people buy something, then a new version comes out, and now the thing they were so happy with is rubbish all of a sudden.. I always think you bought something that fitted your needs, the fact there is a newer version doesn't make the old one bad.. and yes, it will probably do more things but it might not fit your needs anymore..
