  1. Dear Community and Experts, I am dying to implement Non Planar 3D printing in our UM3. This is a great feature to great smooth products, without staircase/stepped surfaces. I am referring to the following video and appreciate inputs on how to achieve the same in Ultimaker 3. Regards, Raj
  2. Hi, How are you guys? First of all I am so sorry if this post are not in the right place. I have an Ultimaker 3 printer and unfortunately I am new in this kind of issues of 3D printing and I had bad luck. When my printer was printing during the night, something bad happened and the print core was damaged. At least three components were in bad condition and now I am trying to find new pieces for replacing the bad ones. So, the damaged pieces are the temperature sensor (PT100), the ceramic resistence and the heatblock. I were using a AA printcore 0.25. My question is if anyone can tell me what the specifications of these components are for replacing them. Or do I have to buy a entire new printcore?? Thank you your help! Best regards, Diogo
  3. Hello Developers, recently I found a missing option in the printer menu of the UM3 extended - so I have to switch the printer on and off again to be able to continue. The situation: Installed is a AA print core and a pla-filament spool. Now I change the pla-spool to a pva one using the spool-unload/load option of the firmware-menu. After placing the pva-spool and pressing the confirm-button a message appears, telling me, that the actual print core is not suited for this kind of filament. And here comes the bug: The only option I have now, is just to confirm this message and to continue loading the filament into the wrong core. That does not make any sense to me. What I would expect here: Either a question like: "Do You want to change the core to a BB one? (yes/no)" and then initiate the core change procedure. Or some kind of "Go back"-button, so I could at least navigate back the menu and then go to "change core" and so on. Until now I helped me by switching the printer off and on again and first change the core then the spool. Thank You in advance of taking notice and hopefully changing this. Best regards, Daniel
  4. 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 ...
  5. So I have a UM3 and I've noticed a consistent problem, especially with the PVA material, that is, during the initial extrusion of the filament, the initial knead of material tends to get dragged into the print instead of staying at the location it was extruded in. This happens with PLA as well but at a much rarer occurrence but pretty much happens every time with the PVA. The temp solution I've done to stop this from affecting/ruining the print is to wait for that stage to occur, have my tweezers ready to pull the knead of material away and make sure it doesn't get pulled in. I notice this happens because after the material is extruded, the nozzle moves "into the material extruded and then the hot nozzle sticks to the material and then it's pulled back into the top corner. I have a crappy video of this (link below, apologies for the vertical orientation). I wonder if it's possible to revert back to the way UM2 extrudes materials where it is done at a relatively high height so the material doesn't get pulled into the print. At the very least, maybe adjust the movement so it doesn't bump back into the material during the movement to the top right corner? Also, the PVA nozzle gets nasty real quick as you may notice because of the PVA that sticks to the side over time (is this normal?) and it's extremely hard to clean. I lost the silicone cover (and buying a new one) due to one of the previous attempts and the nozzle was completely clogged outside. Another issue I've been having is the glass plate seems to be quite warped. This results in me not being able to use the last 10 centimeters of the print area since the material cannot adhere on nicely and results in getting pulled off the glass plate after a few layers. I've tried active leveling and manual leveling but none of this seems to help. I have read in the past on the forum of other users experiencing similar issues with warp glass plates and they at the end sourced one locally to fix the issue. Should I contact the reseller to get a replacement? Thanks in advance
  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. Is this a bug? This is layer 343 in a print. You can see the start of a support line suspended in mid air. Here it is at layer 346. It's starting to grow towards the other support but it's still in the middle of the air It finally joins the other support structure at layer 367. Clearly this doesn't print. You get 24 layers of spaghetti then it *might* adhere to the remaining support and recover enough strength to actually support the remaining print. For background, this is the model I am trying to print. Obviously a good support structure is critical. https://www.thingiverse.com/thing:2255905
  8. Hi, I have two printers, an Ultimaker3 and Ultimaker3 extended. They are setup as group with one of them being the host using the Cura Connect. In previous Cura version, when I pressed the button to "Print over network" it would popup a printer selection menu to choose which one to send the print to. Now after installing the Cura 4.3.0 this window does not pop up anymore and the print is send to the first available. This is inconvenient as I have different color material on each and I'd like to chose which one can print... Can you bring back that printer selection menu? Is there a setting somewhere to enable it back? Thanks Thanos
  9. I was doing manual leveling and follow it with active leveling once a time every month, mostly. No matter how i manual level the nozzles, whenever active leveling is done, the printer will always press nozzle 2 too close to buildplate once print is started. I can see the nozzle was so close that it got pushed back a bit upwards, so close that filament cannot print out of it. Core 1 will always be fine and well calibrated, while Core 2 will always be too close to bed, after active leveling. Either the active leveling is buggy, or the result of Z calibration between the 2 nozzles are not memorized by the machine. Is there a fix to this? I am not sure why this is happening. I suspect the distance between Nozzle 1 and Nozzle 2 somehow was wrong. Now I have to set the machine never to do active leveling, and rely on manual leveling. It will be great if there's a way to manually set the Z distance difference of the two cores in cases like this when the active leveling somehow failed?
  10. Hola a todos y gracias de antemano por vuestras respuestas, ahí va mi problema. En mi caso somos un grupo de personas que trabajamos con un par de impresoras, una es UM3 y la otra UM3 extended. Nuestro problema es que queremos llevar una especie de timeline de todas las impresiones y que estas vayan asociadas a la persona que las hizo. Desde el soporte de ultimaker me comentaron que existía el servicio de Ultimaker Cloud, sin embargo al acceder, intento registrar mis impresoras y no las registra y cada vez que entro siempre me pide registrarlas y no las guarda. Por lo tanto quería saber si lo habéis usado y si os dio este problema como lo pudisteis solucionar.
  11. I am using ultimaker3 printer and cura4. Every thing was going smoothly. All of a sudden the printer started rebooting when a print is started. It reboots during build plate heating. I have not changed any settings. Soft ware version is the same and updated. I have tried it with different files even used the older version of cura for slicing to check if the gcode file is ok but still rebooting. I am using USB to transfer files. I changed the USB also to check if something is wrong with USB. One thing I have noticed is the led light on power supply module also blinks when the printer reboots. I am stuck in the middle with my project. Please help. I am attaching the stl file. Part22-Turbine _Shaft_New.stl

    Bonjour à tous, Depuis peu j'ai des soucis de sous-extrusion... Je n'ai pas changé de filament, la buse AA que j'utilise n'est pas très usées, j'ai juste installer le nouveau cura... J'ai naturellement nettoyé mes printcores, je ne vois pas trop d'où ça vient. J'en ai même profité pour retendre mes courroies. Que j'utilise ma vieille buse ou la plus récente j'ai le même résultat. On voit bien que les trajets ne sont pas comblés et qu'entre les parois intérieures et le remplissage il y a carrément un vide ! On dirait un débit foireux ou un buse bouchée (mais elles sont toutes les 2 bien propres). PS: Ma UM3 a déjà passé 15Kg de PLA/Nylon (+un peu de TPU et PET). La première buse est d'origine (donc bien rongée) la deuxième je ne m'en sers que depuis quelques mois... A ce stade l'UM3 a besoin d'un entretient spécifique ?
  13. Buenas tardes, Desde que compré la impresora NUNCA ha funcionado la cámara de mi UM3, voy a hacer uso de ella y me dicen que tengo que costearme yo el transporte de ida y de vuelta, que como en la factura viene una linea aparte de transporte, que la garantía no cubre el transporte: o pagaba el transporte o no me daban la impresora, y eso que lo compré en una tienda de mi misma ciudad, que estaba dispuesto a recogerla en la tienda, pero me dijeron que el transporte se pagaba si o si. La impresora llegó mal de fábrica, es decir, te mandan algo defectuoso y te cuesta dinero su error. la tienda a la que lo compré se les olvidó avisar de la garantía, lo hicieron, me pusieron en contacto con ellos y ahora me dicen que es la primera noticia que tienen. Me parece una vergüenza que me manden algo mál, que no se me tramite la garantía, que trate con el servicio técnico y me digan que no tenían noticia alguna. Para la empresa que es y lo que cuesta la impresora es vergonzoso el trato y cómo funciona. ¿Habéis tenido el mismo problema? la verdad que me3 han entrado ganas de tirarla a la basura, me ha dado siempre problemas de calidad de impresión, capas que no se unen bien... más me hubiera valido comprar una de 400€ que esta basura....

  15. Hey guys! I am quite new to the Ultimaker and the community. A few years ago I had a different (selfbuilt) 3D printer, but things got very frustrating, so I paused until I bought myself an Ultimaker 3, two days ago. Yesterday I did the whole setup and everything went well and worked perfectly fine. In the evening I did a Firmware Update and shut the printer down afterwards. After shutting everything down for the night, I tried to print today and noticed, that the printer was not showing in Cura anymore. So I checked the network settings on the printer and noticed that the printer was not connected to WiFi anymore. Alright, so I did the whole procedure of connectign the printer again, but it always failed. After I enter the WiFi Password (on several devices by now), the printer states that it tries to connect to the network. This message is shown for a fair amount of time, until I get the message, that the connection failed. I also tried to restart my WLAN router and the printer. In the end I also reset the printer to factory settings as it was suggested in several threads, but nothing helped yet. I did not change anything else about my local network, so this leaves me pretty help- and clueless on what to do next 😞 Does anybody maybe know this issue and can help me? Best wishes Steve
  16. i am trying to connect repetier host to ultimaker 3, but can't connect them. 3d printer connection should be fine, since i can print out stuff with cura. i am wondering is it possible the problem is the port? I connect with IP address and port (80). any help?
  17. I bought a second hand ultimaker 3 extended and noticed it has some ringing or inconsistencies in the y axis. The wall along the x axis looks smooth, but the wall along the y axis looks really rough. Shiny black exaggerates the imperfections, but you can also feel the roughness with your finger and it is visible in other colors. The walls are printed with the default cura profile with a 0.4mm nozzle and 80mm/s speed (30mm/s outer wall speed). Printing slower makes it less pronounced, but even if i print at 20mm/s outer wall speed the y axis looks still worse than the x axis. On my old printer, a wanhao 4x, the outer walls look and feel about as good as the x axis of the ultimaker. Both x and y axis look about the same. It is printed at the same outer wall speed. I suspected it might be a bad Y axis bearing. So i replaced it, and also replaced the rod, just to be sure. Unfortunately nothing changed and the prints looks just as bad as before on the y axis. The ringing or inconsistencies are also clearly visible in this benchy (a part is painted gray). Benchy with rough walls on the y axis, printed in the defualt 0.15mm profile I then printed a bearing from pla, which probably won't last very long. But it did improve the quality of the y axis. It is a lot smoother. Not a great long term solution. Pla bearing and y axis wall with pla bearing Is there something else wrong with my printer or do all ultimaker 3's print this bad on the y axis? Does anyone else has this problem? I attached the test file i used in case anyone wants to test it on their ultimaker 3 (extended). The filament I used is ice pla black but the problem also happens with other filaments. vertical artifacts2.3mf
  18. Hi My printer (UM3) have problems with communication with the print head. I often got ER18 with the text "There is a communication error with the print head" It often occurs when the print is finished and the print head i "homing" to the start position. It´s also occurs after a (by me) aborted print - also when the print head is homing. When I have dismounted/mounted the print heads, I often can print again. Maybe has the ER18-problem started after I in this week updated the firmware, but I´m not sure. What to do? Any suggestions? /KP
  19. All of the camera API URI's return 404 not found. Having digest authorization does not matter, I always get a 404. I have other requests working, I use the same headers and digest authentication. The printer is running the stable version
  20. I want to connect the Ultimaker 3 to our LAN at work, however we use static IP addresses only - the server doesn't use DHCP, and there is no WiFi available (for security reasons). Is it possible to configure the IP address, Subnet mask, and Gateway info on the Ultimaker 3 manually?
  21. Hi there, is been a long time 🙂 im back again with a new ridle with a UM3. so wath' is the problem ? yes, let me in for explain simple, there is "slipping" on Y belt in the machine while X travels. for be more simple, there is the video in "slo mo" https://photos.app.goo.gl/ef7o16kRiKN8W18d8 i tried re align all the pulleys and re tigthen everything but nothing do it. BTW, it hapens one everytime machine starts rigth after a homing but after it no more hapens during stress test or other movement of the XY square. can it be a electronical problem ?
  22. EDIT: For this first issue, of brim printing in support material, I discovered the "Brim Replaces Support" option when searching all of the options that have "support" in the name. So the first part of this is solved. The unnecessary support in the upper reaches is still an issue. I've got a part that I wanted to print with support that had only a small footprint on the build plate. I wanted to print it in this orientation so the long cylinder would print where there was other stuff on the same layer so it would cool properly. Because it has such a small footprint of Material 1, I choose to use a brim to give it extra adhesion. I normally print PLA with just a skirt. As you can see here, the outer brim printed with Material 1 (purple) but the brim around the small footprint (purple circle) was printed with Support (White Material 2). Clearly that brim was caused by the circle (base of a hollow tube). The other problem is that support "Expansion" reached layers above where any support was needed. Generate support was set to only Touching Buildplate. The first slice is showing how the support should be (used Support Blocker as shown in project file). This shows what it generates without the support blocker. This is all with Cura 4.2.1 UM3_PMGearPlate.3mf
  23. Hello there! My U3 messed up a print and I stopped/aborted it. Unfortunately a slightly bigger piece of printed stuff was under the printing bed when the bed came down. So the bed did not touch the end switch and the z-axis started to sound very bad. I switched it off after 2 secs. I had to unmount the switch and press it manually to get the bed free. But the bed is not working correctly anymore... Now, does anyone know if this can be repaired by myself? Thanks in advance!!! Tom
  24. here's the situation: Z Distance between the nozzle in Core 1 and Core 2 seemed not remembered by the firmware, or it is ignored during print, or something went wrong during calibration. Core 1 will always be well calibrated and printing well, however, Core 2 will always got pressed too close to the bed that blocks the filaments from coming out. After Active leveling, Core 2 nozzle always pressed too close the bed during print, as if it is ignoring the result done during calibration.. after running more of tests, it seems that Manual Leveling does not have this issue. I have done a lot of tests, switching print cores(i have purchased one extra print core), and the result is the same. So i guess it is not the problem of the print cores but something is wrong with the machine doing Z calibration. And it seemd to me the machine is ignoring the Z calibration that is done in active leveling, so every time when print started, it went all the way pressing nozzle too close to bed again. Not sure if this is a firmware issue but i would like to post here to see if it shines any clues. Some other users also have this similar problem and is forced to print on one nozzle (Core 1), unless one kept doing manual leveling and forces the machine to never do auto leveling thus not to override manual leveling setting. And this seemed to happen fairly recently, so i guess it could be something about the latest firmware update.
  25. Hello, I have one UMs5, two UM3s, one Prusa MK3S, and one custom RepRap. 1. I'm trying to figure out how to capture time lapse videos of my prints on a UMs5 and UM3. Cura has a time lapse feature built-in under the Extensions -> Post-Processing menu, but it doesn't seem to work with the Ultimaker machines. It executes the gcode that moves the print head to the specified location and back, but it doesn't take a picture. Do I need to use a different gcode than the standard M240, or do the Ultimaker machines just not support time lapse capture? 2. The gcode for filament change (M600) doesn't seem to work on the Ultimakers. The one time I tried it on a UM3, it ruined my print because the printer crashed at the M600 command and wouldn't continue without being rebooted. Is there a better way to do a filament change mid-print that I don't know about? The only time I've ever successfully done a mid-print filament change, I had to wait for the print to reach the layer I needed (which I judged by eye, comparing to the Cura preview of the layers), then manually pause the print and feed in new filament. This is way too labor-intensive when Ultimaker has a built-in filament change feature that works perfectly. However, it only works when the machine isn't printing. 3. When I connect via OctoPrint to the Prusa or RepRap and print a file, I get a control panel in Cura under the Monitoring tab that lets me set preheat and set temperatures, jog the printer in each axis by 0.1 / 1 / 10 / 100mm, home the axes, pause or abort the print, and even send arbitrary gcode. Are there any plans to backport/add some of that functionality to control Ultimaker-brand machines? It would be amazing to be able to run arbitrary gcode. In particular I'd like to tune the extrusion multiplier exactly by extruding 100mm of filament and seeing how much the machine physically moves the filament. The Ultimaker machines seem to over-extrude slightly, especially for CPE/PETG filament. It's very strange to me that Cura has support for these features for third-party printers, but the Ultimaker machines don't support these gcode commands, even though they are built into Cura.
