  1. I'm trying to set up the air manager of a S5 Pro bundle. I snapped the "mounting bracket" into place as a test fit before I threaded the Bowden tubes. Now I cant remove it. Please help!
  2. Update --- Very good news! I'm pleased to announce that all reported problems with the Ultimaker S5 have now been fixed! Read my full post for more information. Greetings to the Ultimaker community. This is my first post. I decided to join and share my experience in evaluating the Ultimaker S5 3D printer. This is going to be a very long post, in which I'd like to share in detail what I observed, the various issues that came up, and my overall impression of this machine. Also, I would really like to hear your own experiences and how they relate to mine, in the hope that I can determine if my observations were the exception, rather than the rule, and to help me decide whether or not this printer is suitable for our needs. tl;dr: Received two (2) brand-new Ultimaker S5 printers in the space of one month. Both experienced frequent freezes/crashes in the touchscreen/UI, had to apply numerous power-cycles (i.e., turning the machines off/on using the power switch) to make them operate. In one machine, the BB print core was DOA. During the first couple of prints, both printers caused the print head to freeze mid-print, and deposit a big lump of molten PVA right on top of the printed object. Did I just get two bad apples in a row? Am I the only one out there experiencing this? Your feedback is greatly appreciated, many thanks. The long version I work in the defense sector, and was asked by my department to recommend a good, reliable 3D printer for our laboratory. I had heard of Ultimaker several years ago, as a well-respected company in 3D printing, that make high-quality, reliable machines. So, after reading about the biggest member of the family, the Ultimaker S5, it was an almost instant decision to recommend it. In fact, I recommended we purchase the Ultimaker S5 Pro Bundle, but was later informed that there were some delays in production for the entire Bundle, but we could have just the printer first. Was really looking forward to the day when the local reseller would come to our lab to deliver and demo the printer for us. Here's what happened: 1st Ultimaker S5 (December 2019) Day 1: Reseller came to our lab, unboxed and installed the Ultimaker S5, installed print cores, loaded filaments, etc., and prepared to do the first test print. Waited 10+ minutes, nothing happened. Bed was not warming up. Touchscreen was unresponsive, s/w inside the printer had crashed. Had to power-cycle the machine. Upon powering up the machine, a "Finished Printing" message appeared next to a checkmark, which was odd, since it never actually started printing anything. Reseller had to do several power-cycles because the touchscreen/UI kept freezing and becoming unresponsive several times. Updated f/w to the latest version, nothing changed. Eventually, the printer managed to make a small print (one of the examples in the official USB stick). The print was good, I was impressed, but also worried about the odd behaviour and frequent crashes of the machine. Day 2: I tried to print a simple, small object. Everything started fine, printing commenced, several layers were completed without issues. Suddenly, the print head froze in the middle of the print, and right on top of the object being printed, but the extruder kept extruding molten material. The head stayed frozen for several seconds and then resumed printing. As a result of this, a blob of material was formed on top of the object where the head had frozen, thus destroying the smooth surface of the current layer (see first 3 photos). This exact same thing (freezing-resuming) happened 3 more times, and eventually the head froze completely, and could never resume. Big blob on object, printout ruined. UI had crashed, had to power-cycle machine, "Finished Printing" message appeared. Not good... Took photos/videos and spoke to the reseller, who agreed to take back the printer and replace it with another one. At least the reseller accepted there was a serious issue with the printer. I thought, "doesn't matter, it's a one-off, such things can happen, will be sorted out". Christmas holidays were coming, both of us would be away, I was assured the new printer would arrive in January 2020. And so it did. Read on... 2nd Ultimaker S5 (January 2020) Day 1 (morning): Reseller came to our lab, unboxed and installed the new Ultimaker S5, installed print cores, loaded filaments, etc. As he was doing all this, the printer's stepper motors suddenly started making a loud noise, as if they were vibrating. Print head didn't move. He was surprised, had to power-cycle the machine to make it stop. Eventually, we came to the stage where the printer was preparing to do the first test print. While waiting for the printing to commence, I smelt something burning, which was something I wasn't expecting, as the previous printer hadn't done it. The printing never managed to start, but instead we got an error message (maybe ER28, can't remember for sure) about overheating in the BB core (at position 2). That's where that burning smell was coming from! Tried a second time (removed and reinserted BB core), same error message. We then swapped BB cores between the old and the new printer, and eventually (after at least 5 power-cycles due to the touchscreen/UI freezing), we managed to do a small test print, and it came out OK. "It was the BB core", I said, "we nailed it". Sent another, much larger print, which started OK. Reseller left the lab, I stayed until late afternoon to keep an eye on the printer and make sure everything's in order. Day 1 (afternoon): Everything was going smoothly, until... BANG! The dreaded blob issue again! Print head stopped mid-print for around 5-10 seconds, leaving a blob of material on top of the object being printed (see last 2 photos). Subsequent layers gradually covered it, and printing continued. I left the printer to continue printing overnight, at the suggestion of the reseller (would complete the next day around 1:30 pm). Left the lab puzzled, frustrated and disappointed. Day 2: Printing from previous day completed successfully and came out beautifully. Really nice to see! But still, the freezing of the head the previous day just spoiled the fun. The blob of material is now buried deep inside the object and cannot be seen. But, what if it happened on an outer surface? What then? My conclusion The Ultimaker S5 is a beautiful machine. Large build volume, dual extruder, choice of easily-swappable print cores, good selection of standard and advanced/reinforced materials, auto bed levelling, Wi-Fi, semi-enclosed chamber (fully enclosed on the Pro Bundle), quiet, aesthetically beautiful, it has it all. Or, has it, really? Well, my experience on 2 brand-new Ultimaker S5 machines painted a somewhat different picture. My impression is this: when this printer works, it prints beautifully, and can produce stunning output. But the problem is that it doesn't always work! The f/w (the software running on the small computer inside the printer) appears to have many bugs and freezes far too often to be considered acceptable. During printing, the print head can freeze right on top of the printed object, releasing a big blob of molten material and thus ruining an otherwise near-perfect print. The most worrying part of my entire experience, though, was that the problems happened on both printers! Not one, but two! I really thought the first one was just a bad apple, the exception to the rule. But seeing the second printer having issues too, I'm beginning to suspect that this is something that really has to be looked at by Ultimaker's design team. 2/2 of problematic machines may be an indicator that something may be wrong in the design and quality control of this printer. It's just very worrying to me, that two (2) machines came out of Ultimaker's production line exhibiting the above problems. Being an Electronics Engineer, with 25+ years of embedded systems design experience (PIC, ARM Cortex-M4/M7), I worry that there may be something bad happening in the embedded system inside the printer. I read about a Linux mini PC that communicates with an Arduino. This may sound OK from a makers' perspective, but may not suit a professional-grade product. If that's true, then there may be bugs that cause those freezes and crashes. The UI crashing regularly during routine operations, such as changing print cores or loading/unloading filament is not a good sign. Most importantly, the print head freezing its movement mid-print and making blobs of material on the print is a major issue that needs to be addressed, no matter how rarely it may occur. The design should be robust enough to guarantee that such a thing is never allowed to occur. Back to my story, the reseller agreed (in fact, they requested) to take back the printer and test it at their own lab, with special G-codes that Ultimaker will send them, so that they are able to observe and address any issues. I must say that I was satisfied with the reseller's customer service. I had to suggest to them that we may have to look at another brand of 3D printer, to which they agreed. However, despite what happened, I really like the Ultimaker S5 (when it works as it should). Cura is also a very powerful slicer. There's a lot to like in this setup, and that was one of the reasons I recommended it. I really hope I get flooded with replies from happy users saying that they've never experienced such unstable behaviour from their machines. Request to the Ultimaker community Please let me know what you think about all this. What are your experiences with this printer? Has anyone had (or is still having) issues similar to mine? Am I the only one to experience such unstable behaviour from an Ultimaker S5? Could it be that I was just too damn unlucky and got two bad apples in a row, while the majority of machines out there work as they should? Be harsh, be critical of my methods, I don't mind. Just tell me I'm wrong. Tell me I did something wrong... If you want any more specific information, just ask. Many thanks for reading my story. I see that the first two posts of a user are moderated, and I hope that my post makes it to the public forum for everyone to see. It may sound negative, but the intent is wholeheartedly positive. What I'm saying above is the honest truth. I can back it up with photos and videos. I have nothing against Ultimaker, and I do hope that the 3rd time the printer comes to our lab, it works flawlessly without any issues. But I want to know if I'm alone in this, or there are others that can relate to my story.
  3. Hi, I have problems printing a box with a lid. The corners aren't perpendicular to each other, therefore I can't assemble the box. The box is totally slanted when assembled and I can't put my finger on it, why this happens. The Box and the lid individually lay flat. I printed the box three times so far with no luck. At first I thought the large bottom area causes the problem, so I designed a big hole in it. That did not help either. Maybe the filament is the problem? Please see attached pictures. I printed the last model upside down with a ton of support. The top layer isn't ideal either, that's why i think the material could be a problem. I hope someone has an idea.
  4. What am I doing wrong that my Pause At Height will not stop my printer during printing. I tried adding a couple of pauses in a print earlier this week and didn't realize that the post-processing carries over to all prints sliced after this, but none of my prints have executed a pause since I added these. Initially the first pause was set to 4mm and every print since then has been much taller than that limit so it should have paused for each print. It seems pretty straightforward from the videos I've seen setting this up in Cura, so I'm quite perplexed. I'm using and Ender 3 Pro printer and I have Cura version 4.4.1.
  5. I normally use the OctoPrint Control tab to monitor my prints, but I happened to notice that Cura's plug-in offers a Monitor page that provides much of the same functionality. It seems to work fine, with one exception: Pressing the "down" button causes the bed to rise, and the "up" button causes it to lower. A little counter-intuitive ... I searched the forums and didn't find any other posts reporting this issue ... is there a way to fix this?
  6. I'll be in contact with support (again) about this, but am wondering if anyone else has experienced it and possibly got it fixed. Sometimes when powered up my S5 will takes hours to actulaly power on. You hit the switch and absolutely nothing happens. Quite a few hours later (more then a couple, less then 12...) it will power up (switch was left on). When it does this, it doesn't make a peek; no fan spin, etc. It is .. bizarre. Anyone else see this? Sending my printer in for service will be a huge hassle. (if it would stay on WiFi I'd just never power cycle it... but it won't. Better then before, but still falls off occasionally)
  7. Hello I'm using in my Python scripts a function which seems to be obsolet in the new release of Cura : extrud = list(Application.getInstance().getGlobalContainerStack().extruders.values()) How to modify this code to get a valid Syntex ? Best regards,
  8. Hello, I'm working with a UM3 and trying to print with two colors of PLA. This works, but I keep getting strings. I watched the video to solve this, experimented with the retraction settings, z-hop, print speed, temperatures etc. I looked in this forum. But it simply doesn't get better. One thing I notice is that it seems head 1 doesn't retract at all. I don't hear it pulling back the filament. When it switches to the second head, it always retracts correctly, doesn't have any strings. But to be fair, the first 95% is done by head 1, so it continually moves over already printed material. Load/unload works fine on head 1. So my guess is it's not broken, but not sure. Anybody an idea what else I can try or check? Any help is appreciated Note: STL's are from Solidworks 2020. Note: The attached photo is taken with the Cura default settings.
  9. Hello, Is it possible to display a message in a Python Cura Postprocessing PlugIn Script. I know how to add a log text via : from UM.Logger import Logger Logger.log('d', "Error" ) I have tried from UM.Logger import Logger from UM.Message import Message from UM.i18n import i18nCatalog catalog = i18nCatalog("cura") Message("Error\n", title = catalog.i18nc("@info:title", "Post Processing")).show() But it doesn't work
  10. Hi, Is it me? Can't figure this out. In previous versions of Cura I was able to hit the blue button and gcode was put on SD card. Right now I have to choose Save to File, change from 3MF to G-Code and hit Save. Thanks Rob
  11. Hello, we recently bought new, original printcores for our Ultimaker 3E. Those are the AA 0.8 and BB 0.8 cores. The installation of the AA 0.8 went well but the BB 0.8 is recognized by the printer as BB 0.4. I already checked: -Firmware up to date (5.2.11, the latest as shown by the UM website) -Pins are cleaned with alcohol However it still gets recognized wrong-is this a known problem ?
  12. Hello I'm looking for a documenation concerning the different property we can get via this function. Up to now I was mainly getting the Value and the Label but I want to know if it's also possible to get the unit and other different informations. Best regards, Cuq
  13. I woke up this morning to my print being prematurely halted and my UMO ulticontroller stating "error: max temp". I turned off the printer then turned it back on to restart the print. Print started fine, but when I came back 20 mins later the same error message was there and my nozzle said it was well over 300 C! Why is my printer giving this error about max temp? How can I fix it?
  14. I just updated to Cura 4.2 on windows 10 home 64-bit (build 17134.885). It won't start. I don't even get the splash screen, just a flicker of something on the task bar, 5 seconds of hourglass and then nothing. I initially got this with 3.6, 4.0 and 4.1, but they worked after I switched them to windows 8 compatability mode. That trick doesn't work for Cura 4.2. Any ideas how to solve this? Cheers.
  15. tried installing 4.4 but as soon as it opens i get a fatal error. any help would be appreciated.
  16. I am brand new to 3D printing (actually helping my 12 year old son). We have a Monoprice MP10 Mini (just bought for Christmas) and downloaded Cura 3.3.1. I tried getting a newer version of Cura but could not find the Monoprice MP10 Mini on any other Cura version other than 3.3.1. I am also using a PC but have a Mac to use as well if needed but could not find any Cura with Mac for Monoprice MP10 mini. In any case, the 3D models that we are trying to print out are not completing and I can't find any error message as to why. We are using Tinkercad to build the model and have tried saving as .STL and .OBJ. The sample cat file completed its print so I know that the printer can complete a model. I also tried printing the Thingverse sample Bunchy and that printed to 75% completion. Simple models like a cube and heart have completed. We are currently trying to print out a Star Wars X Wing and it got to 60% complete and then the printer just stopped with no error. Based on this, I have several questions: 1. Is there anywhere on Cura 3.3.1 that I can see the error messages to try and troubleshoot 2. Is there a way that I can upgrade to a more recent Cura version for the Monoprice MP10 Mini, assuming that will help with my prints. If it does not matter, I have no problem staying on version 3.3.1. 3. Any insight as to why my 3D model is not printing? Can I tell if there is something wrong with the model that we built in Tinkercad. All the pieces look put together and they are all "grouped" so it should come out fine. Thanks in advance for any help you can provide to total NEWBIE in 3D printing trying to help her son with building 3D models. See attachments if that is helpful. X wing practice test.stl
  17. algumas dll do computador se corrompem e para repara-las use o dll suite, analise e repare, assim que ele reparar os dll o cura ira abrir.
  18. Tried twice to install 4.4.0 on my Windows 10 home 64 bit laptop. On startup is freezes at "Loading plugins". The only way to kill it at this point is through task manager and looking at background processes. The install never makes it to showing up on the task bar as a running application. I have installed 4.4 on two other Windows computers (10 Enterprise and 10 Pro) with no issues. Opened a "cmd" window and started it there on command line. It came up after noting that Windows Firewall had blocked some of it. I gave permission for it to run and it started. Now it starts from the icon. FYI, DLC
  19. My front screen was burned in and now it's dying. I can barely see my front screen display on my Ultimaker 3 now. Anyone know if there is a way to fix this? I can't even change out filament and I can barely print by just remembering where everything is to be able to get the print process set up.
  20. Hi, (sorry for my bad English i'm French x) ) I want to print anything that i have modeling in Cinema4D R19 in Cura but when i import my STL file (1cm lader), cura is modifying the scall, i don't have 19x17x13 cm but 19x17x13 mm ! Any people can help me please ? Have a nice day :)
  21. I have a large print (10x12 inches at the base) of Chaos Stones by DuncanShadow. I was trying to save plastic and reduced infill to 10% (it still estimates it will take more than a day to print). As I looked closer at the preview I noticed that there are sections of the actual model (shell, top/botton) that are expected to be printed over infill, but there is no support structure for them. I was expecting (hoping?) that Cura would be extremely clever and build a platform in one of the infill grid cells, build support on the platform, then build the final shell on top of the support. But it doesn't seem to do that, it apparently thinks it can print in air 😊 I suspect what will really happen is that it will extrude into open space and wipe the plastic off on the infill grid wall. Hopefully there will be enough structural integrity that it will complete the shell, I'm not so sure. This thing is basically a ball (a flattened ball), what is the best way to slice it?
  22. The preview in Cura 4.4.0 is inverted, showing the complete structure at layer 1, and moving toward a greyed out image on the last layer. Not sure when this started, never saw it in previous versions. I played with colors on my material, perhaps that contributed? The model prints correctly. This is scaled up (by 7,000%) and rotated 90% from the original.
  23. I'm new to 3D printing and I am experiencing random lines in my 3D prints. Does anyone have any ideas as to what might be causing this? Printer: Ultimaker S3
  24. Hey, for some reason I kept getting a stripe of missing volume when generating my print model preview. I tried this on Creality CR10 and Makerbot Replicator with its standard presets.
  25. Hi everyone! The knurled wheel of the feeder motor (UM 2Go) is out, how could I fix it? Thanks!
