  3. Hi Everyone, Does anyone know what "an error occurred while processing this print job. Line nr = 31391." means? UM3 printing PP Best, John
  4. Hi Everyone! We meet problem in our lab with printing quality with Ultimaker 3. Plastic PLA. We have already changed extruder, checked feed system, changed printing and feeding speed, but from time to time the problem comes back. Pls, look at the photos, maybe you have meet these problems before? What could you suggest in our case? What helped you with it? Thx in advance ;) Best, Sautenich
  5. I have been using UM3 for printing functional prototypes for various projects going on at NIH. As many parts I print require precision, I have to change the print parameters which result in large print times and increased material consumption. Many times, the prints are overnight and the printer runs out of material leaving the nozzle printing in air. It’s frustrating because I have to start whole print again wasting material and more importantly, time. I noticed that the new Ultimaker S5 has something called Filament RunOut Sensor, and I have been reading on your community page that you guys have been working on developing something like that for long time. I would really appreciate it if you have figured out a way to install that on UM3 as it is the primary printer we use Thanks!
  6. Does anyone knows if it´s possible to create own nfc tags for the UM3? The tags from the UM spools can be read from my Samsung S7, but the data format is unknown.
  7. hi to all... is printcore cc 0.4 compatible with um3? is it red by cura for um3? i ve bondtech qr with steel seeder!!
  8. I'm looking for UM3 firmware circa 5.1.xx I recently upgraded to 5.3.0 to enable PETG printing, made a few good prints then started getting spongey prints (lack of extrusion/grinding). I did all the usual checks and a whole bunch of maintenance with no improvement. I changed back to PLA and the same thing! I've even swapped out the AA core for another AA core and still the same problems. I'm using known good print files so that isn't the issue. Anyway the only thing I can think of is that it could be the firmware. So where can I get older versions of the firmware?
  9. Good day folks! We utilize Qualys to scan our network for security vulnerabilities, and a recent scan returned a hit for CVE-2021-23017, which seems to be a fairly nasty nginx vulnerability on our Ultimaker 3 Extended running firmware version 5.3.0. I've been tasked by our security group to find out if the fix for that vulnerability is going to be backported into the version of nginx in use on the device? Thanks!
  10. Hi Everyone, after years of lurking, i have been struck with..."semi tragedy". I have an Ultimaker 3 Extended ( firmware at this point was 5.2 something i think ), and that lovely machine has worked almost perfectly for all those years. With almost i mean: a year or so ago, i noticed that i could not switch to cabled connection, no light would show on the RJ45 connector, and when i tried to run the Wifi wizard, the screen would go blank for 2-3 seconds and the main menu would show. Did not bother me all that much, because i could send print jobs wirelessly via cura with no problems. Last weekend, i decided to make a thorough maintenance run, realign axles, tighten belt, calibrate everything, and decided to do a factory reset clean that too. Well after the factory reset, the Printer would not boot into the menu. It turns on, lights beep, but the LED strips would not turn on and the menu not boot. Shocked, i started looking into the forums, and embarked into a 16 hours odyssey of "trying everything". Long Story short ( or: this is where i am now ) : - Wifi Board removed - NFC Cable removed - Tried docents of firmware recoveries (uSD), AFAIK the only one who breathed life back into the machine is 3.7.7. - Every attempt to update from there "kills" the machine again - Olimex cable is ordered, waiting on it. - Still can´t get connection via Wired connection. i assume i will have to go through the procedure given by the moderator gr5 ? Maybe someone has some hint or help to make me understand what could be broken ? Thanks for any help Chris
  11. I have an Ultimaker 3. I have a BuildTak flex plate covered with PEI sheet. I am currently printing ASA My problem is that the first few layers are very inconsistent. I have relevelled several times but its no better. The metal plate does not look distorted. Do I need a new plate or a complete set with magnets too???
  12. Hey everyone. @Enigma_M4 @fbrc8-erin @3dprintz I've successfully upgraded to S5 feeders on my UM3 with instructions from CarloK. I've put together a detailed write-up for making the upgrades. The doc is still a WIP and I'll be adding more photos, but thought this would be nice if anyone is adventurous. I've been testing it for two weeks a now and so far so good! It gives abrasion resistant feeders and flow sensor. Also the S5 feeder is just way nicer to change filament using the new lever system. The spring lever system of the stock UM3 is so poor in comparison. NOTE: This document is still a WIP. There may be typos or small mistakes. Please do this mod at your own discretion! Its very simple but it does require one small modification to the ultimaker case, so it may void warranty if that matters to you. More photos will be added in the coming days. Also if you spot any errors in the doc let me know. https://docs.google.com/document/d/1xS30mssCCnmrijWDpg-YsJSjPGnsYNUsdmtQHAISqxY/edit?usp=sharing I can also make a new post if everyone feels that this is worthwhile.
  13. Bonjour, Mon imprimante interrompt l'impression avec des messages d'erreur inconnus. J'ai fait un reset complet de Cura 4.8 et fait un reset complet de l'imprimante ainsi que la maintenance complète, ensuite quelques pièces sont imprimées correctement, puis le défaut revient. Que faire ?
  14. Copied from someone else - I didn't write 99% of what is below but I think it's very useful - especially if you are messing with json files on your UM3 and it stops booting. you'll find a recovery image here: recovery.img. You can install this update by putting this image in a micro sd card - but don't just copy the file there you have to do a special process to make it a bootable sd card. here is a nice guide on putting a disk image on a sd card: https://www.hifiberry.com/build/documentation/create-sd-card-from-img-file/ If you are working with MacOS, you can better use ApplePie baker: https://www.tweaking4all.com/software/macosx-software/macosx-apple-pi-baker/ • Insert the Micro SD card in your computer. • Use the IMG recipe section and search for the file. • Click on the Restore Backup button. • Once that is done you can put the SD card back in the printer and check if it boots correctly. Then, removing the plastic cap in front of the olimex board (it is located on the bottom of your printer), find the SD card slot and insert the SD card: The SD card slot is located on the smaller board in the back. (Where the network cable connects into) In order to reach it you will need to remove the micro USB cable in front of it Now, booting up (only once) with the sd card inserted, wait until a green light goes on on the led ring around the control knob. The display will also tell you to remove the sd card and reboot. After all this you probably want to update to the latest firmware as I'm not sure that the link above will always be the latest but the printer will know if it is the latest or not. Please message me with more details that you learn as I have never tried this with an Olimex board (I've done the same basic procedure on a Beagle Bone Black).
  15. This is a project by a group of community members which was also involved in the Mark2 dual extrusion upgrade. More precisely, it's me coming up with an outside the box approach / weird idea for a certain unresolved problem. Smart people like @gr5, @Anders Olsson, @Dim3nsioneer, @rooiejoris throwing in ideas and @tinkergnome who implants the stuff into firmware. My impression of the current state of development when I started this was as follows. There have been filament monitor projects since the beginning of reprap. Only very few made it to some kind of product state, like the one by Aaron Tunell. Manufacturers like Prusa and others recently introduced some kind of filament monitors, with mixed success / reliability issues. The Duet3D guys set their hardware research (laser-based and rotating) on hold because they were experiencing inaccuracies of +/-20%. Well and then there was Ultimaker ... until yesterday with the S5 All these efforts have been or still are struggling to fulfill the most important objective: NO FALSE ALERTS. Otherwise any filament sensor would quickly render itself useless. What we want to achieve Objectives, the obvious part: zero false alerts detect filament runout ("nothing there") detect filament grinding ("nothing/very little moves") Objectives, the challenging part: detect first layer issues (see video below) detect when real flow leaves a certain safe process window and starts to compromise part quality (first, inter layer adhesion will suffer, then classical under extrusion will be visible) and try to counteract, that's where the real fun starts ... Current state of development We chose an encoder and there's a reliably working prototype for an easy to attach external flow sensor, mounted to the entry side of the feeder. Resolution is in the range of 0.015 mm. It's integrated in Tinkerware with a dedicated menu and we (well, he) implemented a gcode command: M591 T0 S1 E0.5000 L0.01695 R35:130 A0.3 P100.00 I leave the parameter interpretation as a little quiz here. Right now I'm working on a modified design which, besides the encoder, doesn't need some parts which cannot be printed and are in the +30€ range to have them manufactured. But most likely some parts will still not be FFF printable. How can I get this? First give us some more time to test and evaluate. If everything works like intended we might proceed like with the Mark2 project. If we should offer this as a product I'd expect a price tag between 70-100 €. And the UM3? That's the BIG question. Like @Daid recently stated their main market is already different. And indeed, has anyone seen any kind of (hardware) upgrade for the UM3 so far? Feeders are the same, mechanically our sensor fits. Electronics, not sure. Ultimaker originally wanted to use a serial interface on the UM3. For the UM2+ we simply connect the sensor's quadrature output signal to free I/O pins, there are enough left (4) for two sensors for a Mark2 dual extrusion UM2. Ultimaker won't do anything to support a sensor on the UM3. Anyway, if a large number of UM3 users would show interest, they might at least not impede a development ...
  16. We’re happy to announce that we’re releasing a firmware update to the popular Ultimaker 3 and Ultimaker 3 Extended. Firmware 5.2.17 will contain: material profiles for the new Ultimaker PETG improved Digital Factory integration bug fixes, among others improved networking packages Ultimaker PETG With firmware 5.2.17 your Ultimaker 3 will support the new Ultimaker PETG material. Your Ultimaker 3 will recognize Ultimaker PETG via NFC and you will be able to select PETG from your material selection screen. Digital Factory The connection to Digital Factory has received the pin code connection, bringing it on par with the S-line 3D printers. Admins in the Digital Factory can secure settings and prevent unwanted changes to devices by unauthorized users. Secondly, the camera stream is now also available in the Digital Factory. The stream is a series of images that will be updated every 10 seconds by the camera in your Ultimaker 3. Lastly the print queue for the Ultimaker 3 can now be modified in the Digital Factory. Bug fixes & improvements Improved networking packages - We fixed some networking bugs that causing print stuttering. Screen bug – We fixed an issue that could, in certain cases, cause the screen to appear garbled or shifted. Active leveling improvements – We fixed some active leveling issues caused by reusing old probing data, which could lead to printing too close or too far from the build plate. UI Interface – Updated all copy to correctly reflect the Ultimaker platform and the Digital Factory Italian translations – We fixed some strings that were incorrectly translated in Italian. Special thanks to Alessandro from Crea3D for reporting! Official release notes you can find here Instructions on how to download the new firmware for the Ultimaker 3 you can find here Thanks, have a great day!
  17. Hello, I just bought a brandnew Ultimaker 3 Extended. Ive done all calibrations after unboxing. Now I have the problem that x and y measurements dont have the same size when I print a 20x20x20 cube. I measured the cube with my Mitutoyo caliper and measured 19.7mm in X, 20.2 in Y and 20.05 in Z. The Z axis is fine. It is not possible to print round parts.
  18. There are a few other topics floating around that discuss accuracy and calibration of the printers, but my issue seems to be above and beyond. First off, I am running a UM3 with 0.4mm Cores, mostly MatterHackers PRO PLA and PRO Nylon material. The issue is that my parts are consistently 0.010" (0.25mm) over size on outside dimensions (OD/PIN), and 0.015" on inside dimensions (ID/HOLE). I have spent a lot of time printing calibration cubes and if I print a single wall cube with 0% infill, my print comes out perfect - as in, +/-0.001 with the occasional 0.005 outlier - but I can live with that, this is a CNC machine. However, as soon as I add multiple walls, the part grows (consistently) to +0.010 overall. This is true for 2 walls, 3, 4, and so on. I can print 6+ walls with the same result. Since the single wall part prints perfect, I have to assume that my material calibration is correct - right? Hopefully this describes the issue thoroughly enough. To combat this issue I have tried: -->negative horizontal expansion This *sometimes* works, but some surfaces (typically inner diameters) and angled surfaces do not get adjusted, so they end up being oversized pins and undersized holes if the surface is not perfectly vertical. --> outer before inner walls this helps, but does not seem to do enough --> adjusting line width I have 0.4mm cores, which default to 0.35 line width. lowered it a few 0.01mm increments with no success. This seems obvious to me since cura just shifts the shell thickness over and you are left with the same "over extrusion" --> Model parts with 0.010" smaller pins, and 0.015" larger holes works, but is pretty inefficient. A lot of the jigs and fixtures I print are typically meant to be machined, but we have been trying to print them in order to save some machine time. Not everything needs to be made from metal. If we know this ahead of time, I can make sure the parts are designed with extra clearance, but this is not always so easy. --> adjust flow rate This is obviously not a good solution, but I tried it and its pretty tough to dial it in and of course underextrusion results in weaker parts I want to point out (again) that I understand this is not a CNC machine milling metal and that +/-0.005" is asking a lot of a printer. however, this parts are consistently oversized, so I feel that there is some tuning or Cura setting that could be changed to compensate for this. Some part that require extra precision will be post machined with a single pass or something, not a big deal, but I dont want to do this with ever single part - kind of defeats the purpose. Sorry for the long post, but I wanted to be thorough. Any suggestions are greatly appreciated. 111222_dowel_fixture.stl
  19. Bonjour à tous, En fin d'impression, le plateau fait un petit mouvement de bas en haut, sur 1 cm environ, avant de commencer sa descente jusqu'en bas. Toutefois sur une impression de 20 cm de haut, le plateau est tout en bas en fin d'impression. Lors du petit mouvement de nettoyage, ça patine dans la choucroute en faisant des grands bruits de claquement d'engrenages puis l'objet imprimé vient percuter la buse. Pas terrible comme comportement !! 😞 Avez vous eu ce comportement ? Savez-vous si ça se règle ? Merci
  20. hello, today i installed the new firmware and the new cura (mac). big problems now. can´t print anymore. always shows: print failed - and makes restart. is there any other way than to restore the printer via sd card? thanks and best regards
  21. Hello Users of Ultimaker 3 Printers. I am having surface defects on my prints with Ultimaker 3. I believe the problem could be belt tension, so i followed the instructions to adjust tension. The surface problem persists and the corners appear to strongly overshoot while printing at 30mm/s. Any suggestions for a solution? Anyone familiar with the problem, why does it happen and how to solve it? I attached pictures.
  22. I have made some labels to mark my milling tools (SK40) as per picture The material i used is PLA by Ultimaker. Initial it is flexile, but after a few month the arms break. Who can recomend a better material?
  23. I have a theory that thinner layers and thinner extrusion leads to more warping. The basic thought I have in my head is that if you're printing thin layers, near or below the nozzle width, then you're smearing and stretching the filament, leading to higher stress and potential warping. It's easy enough to find a print that's prone to warping, print with different settings and then eyeball the result. But I'm wondering if anyone has taken a truly scientific approach with this and has good numbers? Maybe even measured stress with some fancy hardware? What do you think? Agree or disagree? Did I miss something obvious or something counter-intuitive? Know of any existing hard data?
  24. Now it's my turn to report that the upgrade to 5.2.18 and Cura 4.11 caused my UM 3E to fail. At my first attempted print, it complained about leveling not working properly. I restarted the same print and it printed without problem for perhaps 7 of the 10 hour gradual infill print. I was not present when the print failed with a filament volcano crater and the plate and extruder stuck at the failure point. It could of course be HW fault but this printer has worked flawlessly for almost 4 years and failed directly after the wire internet FW upgrade. My impression is that booting 5.2.18 after the failure took a long time. I changed to the current testing FW wire internet download, which completed without error message. I then found the update file to 5.2.11 and applied it via USB without error message. It now boots in a more familiar fashion. I do not have screen garbling. After browsing this forum, I realize that this is a long-standing problem, which means that I think I should try to find a known well-functioning FW version before wasting more time. Am I correct to believe that 4.3.3 is the latest well-functioning FW version? I didn't think to make a note of the FW version before going to 5.2.18, so my first step is to try to figure out what version I was upgrading from. If I remember correctly, my previous FW did a 3-point auto-leveling procedure. I don't recall it making the clicking sounds that it now makes during boot. Is this information enough for telling whether it was on FW version 4.x or 5.x? In various threads in this forum I have found the USB update file for 5.2.11 and 5.2.18, and recovery image 4.3.3, 5.2.16 and 5.2.18. I was able to figure out the download link for the 5.2.16 update file from the 5.2.18 update and 5.2.16 recovery links. I am aware of the unofficial restoration procedure. Is there a USB update file for 4.3.3? Could you please link to it? Aaargh!
  25. 3 weeks ago I installed a new firmware update on my Ultimaker 3. I recently did a long print of 9 hours that I left overnight. Print had some trouble on the final layer with extrusion (did some grinding) but nothing too weird. Removed the print like normal and turned the printer off. Now I try to turn on the printer and it does nothing. Checked the cable and power but these all work (the fan turns on and gets power) but no lights/display is not working. Attached the printer to a monitor (removed the bottom part so I can access the board) and it only shows a linux pinguin with "U-boot 2016.05-ultimaker-some number and a date from 2018". I found some threats here on using SD cards for a recovery.img but most recovery.img links are broken. And those issues were during failed firmware updates, but it printed fine for weeks. So any idea what it might be??
