Support was concentric 3d with dense support layer on top and bottom. But again - the support worked fine so far. What I worry about is why the ooze shield did not print well. Looking at the marked areas, you can see that layers of the ooze shield did not follow the round outline but went straight instead. Interestingly this recovered then on higher layers. The printhead did actually follow the outline but the layer did not stick to the previous layer. I'd like to understand why- Z-Heigt should have been perfect and as the first layers did stick well, I do think that's not the issue. I can only imagine a temporary drift of the temperature (likely a drop in temp if any)? But that is hard to control/find out - if not any hidden logs might be available?

Well, the wipe tower is one thing. What really worries me is that the wipe wall was so bad. This picture shows the lower area of the print: When you look at it in detail you recognize that the layers did not stick well to each other from time to time. The PVA was new & fresh from the sealed bag. No signs of humidity, no strange sounds from the filament. I do not think this is related to the horizontal expansion of the support? By the way, interesting print you did!

No reason, your wellcome! That's what a forum is for - sharing knowledge;-)

I've just tried it. You can just disconnect & take off the whole thing, no problem. When loading filament, the UM3 just tells you that he did not recognize the spool, so you have to choose manually regardless of the spool you use. Works fine for me so far. Except that there is no "load" profile for PETG...

So I'd printed a "Sylveon" (found on thingiverse) just for curiosity. This thing needs a lot of support, so I used the delivered PLA & PVA. Well, the print did not end up all bad, even if there are some little defects. What really does bother me with this print: - the wipe tower got kicked off 1 1/2 hrs. before it finished - the wipe wall does look really sh.. - and therefore quite some little defects are in the print Any suggestions regarding print settings for such an object? Major problem was the wipe wall not really "sticking" - higher temp? Layer height was 0.1mm, PLA-temp at 200°C, PVA temp at 220°C.

kcel - thanks a lot, sound logical. Also, in the other thread, I read about the instructions on the UM3 display might be wrong in the middle of the procedure... Will try the alternative approach and report back. Just need to wait until the current "sc...e"-looking print is finished;-) --- UPDATE: kcel, you made my day! I did screw in the bed screws completely, then loosened them about 3 complete turns again. Did a manaual bed leveling then and when it said "turn the screw" at the rear position I used the dial wheel to move the bed electronically instead. Followed the rest of the "on screen" instructions as displayed. The automatic bed leveling afterwards worked like a charm! Current print seems to run smooth, noise of Z-correction is very little - likely the manual one was not too bad:-) Again, thanks, Kcel!

kcel, thanks for the tip. So that is what is meant by ""Ensure the build plate is not levelled to loosely. There should be at least 0.5 mm distance between the nozzle and build plate before a probe starts."", right? Actually I did switch off active leveling earlier today and have a print running right now. It runs with PLA&PVA and the wipe wall looks simply "scheisse" as we say in german;-) To me it seems there is a problem with the BB-core but can't figure out what it is.

Hi! So today in the morning I took out a printed part of the UM3. Noticed it seems to be that my UM3 does some serious overextruding, since the gaps in the object where too narrow & this is not due to design. But since the next thing I wanted to print was not that critical regarding measurements, I loaded PVA into Slot #2 and started the print. The UM3 did the active-leveling thing & got stuck at the front left corner. After several retries he gave up and mentioned some "error 22". I looked after that and learned I should redo a manual leveling. Which I did and I followed the instructions on the screen to the word. I even used a 1mm gauge to make sure that really is exact. After that I started the active leveling again. It again failed with an error message saying "Difference between detected height of both PrintCores exceeds realistic values". I did retry the manual- and the automatic bed leveling quite a few times today (actually spent 4 hrs already on this), but the result remains the same. Sometimes I could finish the automatic leveling but then the automatic leveling before the print failed. Even removed and re-inserted both print cores already, just in case something got stuck. Only thing I noticed was, that the BB-PrintCore has a slight resistance when pressing together the handle bars, which the AA-Core does not show. Any help available? I quite a bit dissapointed to see this expensive machine fail right after the second print. P.S.: on the page reg. Err.22 it is mentioned: "Ensure the build plate is not levelled to loosely. There should be at least 0.5 mm distance between the nozzle and build plate before a probe starts." I do not really understand what is meant by that & how to ensure this. Can somebody explain that to me?

So I have removed everything, installed Cura 3.2. (beta) - still crashes... Same with Cura 3.1 I then removed everything again after making a reset of Cura as described here: https://ultimaker.com/en/resources/20499-reset-cura-2-1 Thereafter I did a fresh install of Cura 3.1 (as being the latest stable version). Still the same problem. Anyway I found the solution - at least for my problem: Within the Systemsetting of the Mac, click Network. Click on "further options" (or is it more options? Translated from German;-). Select "Proxies". Check if in the list of protocols the "automatic proxy configuration" (or discovery) is activated. If so, uncheck it=disable. Then try again to connect to the printer via Cura. On my Mac this works now.

So did you try to run the UM3 without the spool holder attached as well?

Reg. PolyBox: Kman, how did you position your PolyBox behind the printer? Seems a bit of a hassle? Maybe I'll try whether the UM3 works without the NFC-sensor as well because that spool holder is in the way...

I wanted to print with just one nozzle. Since there was PVA in number 2 I unloaded the filament and took out the 2nd printcore as well. Guess what - I could not start a print that was sliced for just one nozzle... I also recognized that the printer always seem to heat up both printcores - even when the printfile is using just one nozzle. While that may seem to be not a big deal, I think it is. Because heating up the filament without extruding later on degrades the material over time and can easily lead to clogging over time. Since there are always remains, even when you did unload the filament, this might be one of the reasons why a print head cleaning seems to be quite often needed with the UM3.

When I look at the first print my UM3e produced today - a benchy of course - I see two things I do not like too much: - the diagonal lines visible at the side of the cabin - the rough surface at the lower part of the benchy The first issue I already have learned this might be a problem of the UM3 and may be related to the way the stepper motors are driven? The second issue - rough surface at lower layers - is a bit tricky. I did use the silver UM PLA that came with the printer and the standard profile for that in Cura. So bed Temp was at 60°C, print temp was 205°C. Does somebody have some hints to improve?

Well, with every company and every products there can be defects. As lon as that is in some reasonable limit, I would not complain. What's crucial is how the manufacturer handles such defects. I've seen good examples of handling defects and recently I've seen a really bad example (of not handling defects...). I do not think that this is a matter of the companies size. A small company that does not handle such things the right way will hardly become big...

Ah, active leveling, okay... but that's really loud... And yes, it went less noisy the longer the print went. The benchy came out quite well, some details looked better then the one I printed w. the R3D N2 but overall the print quality is relatively equal. Maybe the UM3 is a little bit better with the overhangs, it seems. But after all it is also a different PLA.

Kcel, yes, as said: "By the way I have Cura 3.1 and Cura 3.2 installed in parallel on my Mac - may this causes an issue? While I have been told it should not..." Problem is - I do not know how to completely uninstall Cura on the mac - because simply moving the appl. to the trash can will likely not remove everything... Could also be due to the fact that I renamed the app to Cura 3.2 - but that should not influence the actual directory structure, as far as I know the mac...

Thanks, Kcel! Oh my good, that's a long file full of errors... This seems to be related to the crash: 2018-01-25 18:57:18,964 - DEBUG - UM.Controller.setActiveStage [155]: Setting active stage to MonitorStage 2018-01-25 18:57:19,419 - WARNING - UM.Qt.QtApplication.__onQmlWarning [269]: file:///Applications/Ultimaker Cura 3_2.app/Contents/MacOS/resources/qml/Settings/SettingCategory.qml: Object destroyed during incubation 2018-01-25 18:57:25,111 - DEBUG - UM3NetworkPrinting.DiscoverUM3Action.setKey [98]: Attempting to set the network key of the active machine to ultimakersystem-ccbdd30048b2._ultimaker._tcp.local. 2018-01-25 18:57:25,114 - DEBUG - UM3NetworkPrinting.NetworkPrinterOutputDevicePlugin.reCheckConnections [233]: Connecting [ultimakersystem-ccbdd30048b2._ultimaker._tcp.local.]...

P.S.: I checked reg. that warning. The folder "Ultimaker Cura 2.app" does not exist within Applications. It's actually "Ultimaker Cura 3_2.app" on my Mac. So I did set a log.link"Ultimaker Cura 3_2.app" to "Ultimaker Cura 2.app" - which did not change the crash when connecting to the printer:-( By the way I have Cura 3.1 and Cura 3.2 installed in parallel on my Mac - may this causes an issue? While I have been told it should not...

Where do you find the logs? Asking since when I try to connect to the printer, Cura (3.1 and 3.2 as well) always crashes... Btw. I am using a Macbook Pro w. the latest macOSX installed. Using the Ultimaker 3 - App on my iPad works with the UM3e.

Agree, I could design it in two parts and that would possibly be easier to print. But due to the "customers request" (don't argue with mother;-) it should be a round knob so it will still require support. Let's see how well the breakaway-support works here. Currently I am more concerned about the noise the UM3 makes... This strange knocking sounds, and the frequent beeping (seems to be from Z-Hops) - annoying...

So just right before my lunch break the UM3e arrived - good timing, yellow santa;-) Did have some problems with the setup - filament loading did not work. Had to clean both both print cores before it worked in the end. Even though I did not do the cold pull it now works. I did not find any guidance how to adjust/check the feeder tension for the UM3 - if somebody has some info? This really looked a bit "bad": But it is quite loud and makes strange knocking noises during printing. The knocking is as loud that it transfers via the floor... I can not imagine this to be normal? Can somebody confirm that the UM3 is way louder than the Raise3D N2? Unfortunately I can't upload the audio file I recorded here? The print looks okay so far (still in progress). But the noise scares me...

Just did so. Yes, turning off build plate adhesion frees up quite a bid of the buildplate.

Well, I did print this thing already (on the R3D N2) successfully without warping issues. Unfortunately I did have to print the support with ABS as well and the result did not really look good. That's why I try to find another way to print is with "decent" surface quality. What alternatives do you have in mind? One material I know is BioFila PowR, that easily can outperform ABS reg. temp. and strength plus is easy to print (not sure about that on the UM3, will test). BioFila is made by "TwoBears" which is a small german company - not shure whether that is sold "around the world" already. Aquasolve reads promising and seems to be relatively cheap. Curious to learn more about it.

Thanks, nallath. Can you list those settings that one would need to change therefore?

Hm, a bit irritating, at least. In the specifications document for the UM3 it is clearly stated: Build volume Left nozzle: 215x215x300mm Right nozzle: 215x215x300mm Dual material: 197x215x300mm
