  1. hey, So I'm trying to print multiple objects on my UM2+ext, and it underextrudes severly see picture The one below is taulman bridge, no prob in the middle, colorfabb PLA, no prob Up, taulman bridge but printing 20 same models at the same time, Not good on any of them They all use the same settings, can't find the way to copy/past all settings from cura and I'm shure, the settings I'll give you will not be relevant ^^ I'll just say 100% infill, 70mm/s speed, 6.5mm restractation. merci beaucoup !
  2. Hello, I notice that despite having my endstop set lower, cura does not lower the z axis as far as it could go when printing the first later. This is a big problem because I don't get good adhesion whatsoever, nor an accurate base layer, which is essential for starting the print. If someone more experienced than me could tell as to why this is and how to fix it, I would greatly appreciate it. I'm a bit of a newbie to cura and really 3d printing as a whole. Thank you!
  3. Hello everyone, I have been testing a new material called PURA from AprintaPro. This material has a great texture finish but in my Ultimaker 3 is sticking to the nozzle until it detaches itself and end up in the print in the form or blob / zit. (see pictures attached). I have been in contact with PrintaPro and they gave me some advise including a Simplify 3d profile tested on the Ultimake 3 in their offices, but the resolt is the same. I should say that I am using a 3D Solex Hardore printcore with a 0.8mm nozzle. I have tried all different temperatures, the best one so far has been 190 deg. this is the link for the material datasheet: https://www.aprintapro.com/shop/printament-pure/ Please help. I really want to make this work. Thanks Fulvio
  4. Hello, I have a highly modified Da Vinci 2.0 that has been loaded with Repetier and has an E3D Chimera Extruder. I liked the striped down version of Cura that comes with Repetier so I decided to download your full version 2.6.2. Let me just say I had no idea how much better the full version was.. It has made a 200% improvement in my printing results, especially with my dual extrusion. I have just one problem I can't seem to correct. When I set up the dual extruders in my custom printer I set Extruder 2's X-offset to -18 (distance Chimera extruders are separated). Unfortunately when I do this it blocks of 18mm on each side of my print area on the X axis as unprintable space.. My print area setting are as follows X (width) = 210 Y (depth) = 210 Z (height) = 200 X min = 0 Y min = 0 X max = 240 Y max = 210 I have more than enough X-axis travel to print the full 210mm and am able to using Cura through Repetier but would most definitely prefer to do so with the full version. Is there any way to keep Cura from blocking off that space? Thank you for any assistance you can provide
  5. tl/dr: Is there a way to use Software Leveling with Cura 3.x on a non-Ultimaker printer? I love Cura, it is great software, thank you! I have a Rostock Max v2 (delta), and was able to import a profile for it. Now I'd like to use Software Bed Leveling to get a great print on the delta, and I'm not seeing it where I thought it would be from reading these forums (Settings > Printer > Manage Printer) Is there a workaround to use it? Screw-turning based leveling is... not great.

    Cura overlap

    Hello Does anyone know how I can move objects closer together so I can print more objects at the same time. The screenshot shows a lot of unused space and I would like to optimize my available space.

    Ultimaker Cura 3.3 | Stable

    Ultimaker Cura 3.3 is available from today! Following the news from yesterday, a large part of the news relates back to the Ultimaker S5. Among others Cura can now also create a UFP. UFP (Ultimaker format package) is a new file extension that contains compressed gcode and a preview thumbnail. Using this extension enables a model preview (similar to the solid view in Ultimaker Cura) on the Ultimaker S5 touchscreen and in Cura Connect. Since we also introduced a new material, 'Tough PLA' yesterday, the material profile can now also be found in the latest Cura version. Tough PLA prints as easy as regular PLA, except it is as strong as ABS. Which means if you are looking for strong prints it is definitely a material worth exploring. The prints with the same temperatures as PLA, which implies it is equally heat resistant. Besides aligning Cura with the recent expansion of our product range, we have also added some new features. Ultimaker Cura is now equipped with a 3D model assistant. The 3D model assistant triggers when you want to slice with ABS, PC, PP or CPE+ and can give you tips on how to potentially improve the quality and reliability of your 3D print. - More good news is that you can now also easily do single extrusion prints, when your model allows it. Using single extrusion mode also makes the ‘print one at a time’ feature available for the Ultimaker 3 and Ultimaker S5. You can easily disable it by right clicking on extruder 2 and enable/disable it from there. - The prime tower has now been made round instead of square, which should result in a smoother toolpath and a sturdier prime tower. - Support blocker also made it into the stable version. @ahoeben , thanks again! You can now generate a cube mesh to prevent support material to be used in certain areas within a model. Each cube can be scaled, rotated, and moved with the standard adjustment tools in the left side of your screen. - Bridging. Many thanks to @smartavionics . It is still a fairly new feature, but it allows Cura to check for bridges and opens up more configurations to tweak for better briding. Finally; three new plugins have been added; Scalable extra prime, Print temperature offset, and Enclosure fan. I've mentioned some already, but I want to thank everyone for there help in realizing Ultimaker Cura 3.3. We couldn't do it without you! I'm talking about @ahoeben , @smartavionics , @thopiekar , Pheneeny, krios-fabteam, dagoma3d, uBuild-3D, maukcc, timur-tabi, pouncingiguana, velbn, and Gordo3di. Can't wait? Download Ultimaker Cura 3.3 here! Not entirely convinced yet? You can read more about these features and more on our blog! Looking forward hearing from you, and make sure to share your feedback with us. That is the only way we can continue improving on this wonderful slicer!

    3d printer support

    Good afternoon, My name is Jorge, and I am an architecture student. I'm doing an end-of-career job on 3D printing media. I am using your program (Ultimaker Cura) to generate the support of a piece, and analyze it. I would like to know if it is possible to export the print support and the internal structure of the piece that generates the program to another 3d editing program. As rhinoceros, autocad, 3d max, etc. This would be very helpful to me. Thank you very much. Jorge Galindo.
  9. Below is a workaround for running Cura under Ubuntu / Linux Mint on laptops with with NVIDIA Optimus (hybrid Intel and NVIDIA graphics). My laptop's gen 4 Intel CPU only supports OpenGL 3.3, at least under Linux Mint Mate 18.3 (based on Ubuntu 16.04 LTS) which means Cura defaults to the "Compatibility Mode" layer view. I tried several MESA versions including the native Ubuntu repository and various PPA's including oibaf-graphics-drivers with no success. I have not tried running Cura under Ubuntu Mate 18.04, so it's possible the newer distro supports OpenGL 4.x for my older CPU. If you have a newer generation Intel CPU that supports OpenGL 4.x, there is no need for this workaround unless you want Cura to run under your NVIDIA card. To check your OpenGL version: glxinfo | grep -i version NVIDIA Optimus OpenGL version: optirun glxinfo | grep -i version The workaround is to extract the AppImage and modify cura.sh to run with "optirun". Example: Cura-3.2.1.AppImage sudo mkdir /mnt/Cura sudo mount -o loop ./Cura-3.2.1.AppImage /mnt/Cura sudo mkdir /opt/Cura/Cura-3.2.1 sudo cp -a /mnt/Cura/* /opt/Cura/Cura-3.2.1 sudo umount /mnt/Cura sudo nano /opt/Cura/Cura-3.2.1/usr/bin/cura.sh Change the line: cura $@ to: optirun -b primus cura $@ Ctrl+x and Enter to save the file Note: “optirun cura $@" runs Cura but the drop-down menus do not work correctly without "-b primus". To run the extracted AppImage: /opt/Cura/Cura-3.2.1/AppRun For this to work, you need NVIDIA drivers and bumblebee. The clearest instructions I have found for installing bumblebee are here: http://lenovolinux.blogspot.com.au/ I am using the following: nvidia-384 and supporting libraries from https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa bumblebee, primus, and virtualgl from https://launchpad.net/~bumblebee/+archive/ubuntu/testing intel, mesa, and supporting libraries from https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers
  10. I have one roll of Black PLA from ADD3D (made in Sweden) with these parameters in extruder 1: Density: 1,24 g/cm³ Diameter: 2.85 mm Extrude temp: 200°C Retract: 2 mm Retract speed: 25 mm/s Standby temp: 175 °C Fan speed: 100% In extruder 2 I have original yellow PLA from Ultimaker with the predefined profile in Cura: Density: 1,24 g/cm³ Diameter: 2.85 mm Extrude temp: 200°C Retract: 2 mm (also tested with 1mm at 210°C) Retract speed: 25 mm/s Standby temp: 175 °C Fan speed: 100% Heatbed at 60°C and I have a complete enclosure (Top-Hod and front door). The black PLA is printing with exceptional good quality but the Yellow is behaving extreemly strange and produces a full birdnest of strings. Unfortunatly I removed the strings by hand before I took any pictures (doh 😣 ). It seems like it has been feed as it should because there are no marks on the PLA filament indicating otherwise. First print: The black i perfect and even very small details such as the "bolt holes" in the base top surface are perfect. The Yellow PLA from Ultimaker however is not performing at all. These is all aout of the box, no parameters changed. Then I tried to rise the temperature a bit to 210°C and retract to 1mm and it got even worse. The upper half of the second yellow stripe (from the bottom) should be solid yellow without any material change, but that part is the worst. I don't know if this is because of the PLA itself or if Cura has messed it up completley? I have also attached the project file for the first printout. UM3_Tile_Wall.curaproject.3mf
  11. Hi, if you are using Linux and feeling like trying the cutting edge of Cura development then head over to https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0 where you will find copies of my current Cura installation. They are based on the Cura master branches + my own additions and tweaks and will contain all known bug fixes that have been merged to master. These are not AppImages but an archive of an installation built on a Ubuntu 16.04.4 system, just unpack and then execute cura/bin/cura.sh. Supplied with absolutely no warranty, YMMV.
  12. I'm having issues with supports failing due to underextrusion where the support starts printing. Is it possible to randomize the starting position for supports only? Thank you

    VillaScale_model

    Hi guys! I am not completely new in 3D printing, bought my Ultimaker2 couple of years ago and its been unused for a year until now. What I learned is many things by that and one thing is that open PLA filament ageing! the xy steelarms needed to have some oil but then everything was up and spinning again. I printing scale model of a new built villa. 33 more to go! One of them I du in the maximum size printer allows me to. I just drop the parts in Cura and Print. Remember if you have several of parts to print make a reference frame to with each part. otherwise I noticed that scale not will be right. When I split models to create a bigger one I do "tung and groves" They then snap nice together without need glue. In the staircase it was tricky, but I did holes to put in a piece of filament string, remember do the hole slightly bigger:) Happy printing guys.
  14. hello, i'm calibrating my UM2+ext and I'dd like to acces the flow rate in Cura, but it's simply not here, when I check in the options I have put in my taskbar, there is a "!" next to flow and it says : "This setting has been hidden by the value of the G-Code Flavour. Change the value of that setting to make it visible." I don't have this problem chen I change Gcode flavour to marlin or when I use another printer ! it has to do with theUltimaker2 Gcode Flavour, but why ? makes no sens to not access the flow ( or extrusion multiplier, call it has you wish 🙂 ) Anybody has a clue on what's going on ? Merci Beaucoup 😄
  15. Hello, I am very new to 3D printing (only had a printer for 3 days). I am using Cura 3.3.1 and while I don't have experience with other slicer's one thing I have noticed from parts I have made from Thingiverse is that the face patterns (top and bottom) are different, and to my eye much less desirable. What Cura 3.3.1 appears to do is trace the parimeter and then continue that patter until if fills the face, and in many cases the angle at which they come together is a small acute angle sometimes leaving "holes" or gaps. For example a xyz calibration cube I printed(https://www.thingiverse.com/thing:1278865), the Z (top) surface had visible gaps which after the print I confirmed it is actually present in the Cura sliced file. However when looking at others parts it appears the slicer generates the parameter and then fills in a continuous back and forth motion or what looks like a cross-hatch (for example the thingiverse linked cube, however it looks maybe under extruded). Some of the pictures I have seen that use this method is Cura, but older versions, ex 15. I prefer this look as I think it looks cleaner. That being said is there any way to change this in Cura 3.3.1? Thanks in advance for your input
  16. Bonjour, J'utilise CURA depuis 2 ans et ce slicer offre une multitude de réglages , presque trop a mon gout . J'ai un peu de mal depuis la version 2 car les nombreux paramètres sont pour certains difficiles a aborder, j'ai également du mal a sentir leurs effets. J'utilise de façon très régulière la version 15.04.6 et forme quelques jeunes a l'impression 3 D. J'ai une question extrêmement simple , serait il possible d'intégrer en 15.04.6 dans l'onglet Simple-Filament un réglage de pourcentage de débit qui serait bien plus utile que le pourcentage d'épaisseur de ligne sur la première couche qui n'offre pas du tout les mêmes effets. Ce même réglage pourrait également figurer dans les versions suivantes et serait certainement très apprécié. Nouveau sur ce forum je ne sais pas si ce sujet a déjà été abordé. Merci d'avance de votre réponse.
  17. Say I create a forked CuraEngine that works for some unique, specific application, and I want to expose that through the Cura desktop program so people can actually use it. Is there any way to create a plugin that modifies the toolpath planning behavior? I've been reading the documentation and it doesn't appear possible. If it's not possible through the plugin system, it seems like the options are: 1. Add the functionality to the main branch of CuraEngine and Cura, and enable/disable it through user settings. 2. Fork both Cura and CuraEngine, and distribute a modified version. New to this project, let me know if there are other ways or if I'm missing something obvious!
  18. I created a new profile for my custom printer with a chimera extruder. The second nozzle has an offset {18.1; 0.6}, which I entered in the appropriate field in the settings of the Cura. When I cut the model for printing with any of the nozzles separately, everything is fine, but when the model should be alternately printed with both extruders, then an incorrect generation of g-code occurs. The fact is that when switching to the second extruder, the following lines appear in the code: ;LAYER:1 M140 S60 M106 S63.8 M104 S195 G0 F3600 X0.00 Y0.00 Z0.45 G1 F1800 E67.02626 G92 E0 T1 G92 E0 M109 S200 M104 T0 S175 M106 S127.5 G0 F3600 X-18.1 Y-.6 Z0.45 G1 F1800 E45 G0 F3600 X-18.1 Y9.4 G0 X90.64 Y175.78 G0 X91.208 Y176.306 G0 X214.97 Y252.47 M104 S210 This code occurs every time you switch to a second extruder. It is not clear why here these two lines: G0 F3600 X-18.1 Y-.6 Z0.45 ... G0 F3600 X-18.1 Y9.4 They both instruct the printer to move the extruder carriage beyond the print area, to negative coordinates. Naturally the printer can not do this, the carriage rests against the frame and the engine skips the steps. After that the carriage moves back to the print zone but it skips the steps and as a result a shift occurs. Of course you can delete these lines with the help of post processing but I would like to know why this is happening at all? This is similar to the code for wiping the nozzle, but how did the developers allow it to generate coordinates beyond the print area? How to fix this?
  19. Introduction The 3.3 beta introduces new functionality that is intended to improve Cura's ability to print bridges and overhung areas. The current Cura code base has long had the ability to detect when a skin region spans across islands of support and those skins that Cura thinks are bridges will have the direction of the lines aligned with the detected bridge detection. But nothing was done to detect walls that spanned unsupported areas and no changes were made to the wall or skin print speeds, flows or fan speed. The new bridging functionality does now detect when walls cross unsupported regions and it does now modify the print settings for those walls and skin that are determined to be unsupported. This topic introduces the new settings that are grouped together in the experimental section and are enabled using the Enable Bridge Settings checkbox. The settings Explained You will immediately notice that there are quite a few settings. Why so many? Well, I realised pretty early on in my experimentation that modifying the skin settings for the first bridge skin and then using the normal skin settings for the skins above the first does not always lead to a good result. So there are settings to not only modify the print speed, percentage flow, density and fan for the first bridge layer (bottommost layer) but also for the two layers above. If you want to keep things simple you can un-check the Bridge Has Multiple Layers checkbox and then only the first bridge skin layer settings will be modified. The settings used for the bridge walls are Bridge Wall Speed, Bridge Wall Flow (aka line diameter) and Bridge Fan Speed. Also relevant for walls are Minimum Bridge Wall Length which only considers wall line segments that are longer than this length as bridges. Shorter wall line segments are just printed using the normal settings. Bridge Wall Coasting controls a feature that reduces the pressure in the nozzle as it approaches the start of the bridge. This is necessary because the extrusion rate will need to be very much reduced from the normal rate as the speed and flow used on the bridge is likely to be less. If this is not done, the wall line tends to droop very badly at the start of the bridge. Finally, there is Bridge Wall Max Overhang which controls how much a wall line can overhang the layer below before it is considered to be a bridge wall line. By default it is 100% of the wall line width so the line has to be completely over air with no overlap whatsoever with the layer below. Reducing the value of Bridge Wall Max Overhang means that the line doesn't have to overhang the layer below so much for it to be printed using the bridge wall settings. See below for an example of its use. For a given material and print temperature, there will be some combination of the bridge wall settings mentioned above along with Bridge Skin Speed, Bridge Skin Flow (aka line diameter), Bridge Skin Density (line spacing) and Bridge Fan Speed (and the similar settings for the 2 other skin layers) that produces the best results. This is where the fun starts because it's going to require a lot of experimentation to come up with suitable settings. The default values are tested with PLA at 200deg, 0.4mm nozzle and 0.2mm layers and may work OK, or not (YMMV). One other setting is Bridge Skin Support Threshold which is the percentage of a skin area that is supported for it not to be considered a bridge. i.e. skin areas that are supported for less than this percentage (default 50%) are considered to be bridges and will be printed using the bridge settings. Skins that are supported for more than the threshold value will be printed just as normal. Here's some picture that, hopefully, will make things clearer! First, here's the settings showing some typical values: Here is the first bridge layer, I am showing the layerview as feedrate so you can see the speed changes on the bridge. Notice also the coasting just before the bridge walls start (the walls are printed anti-clockwise): Here's the second and third skin layers: Finally, here are a couple of images of a model (thanks to the community member that sent it to me) that has some overhung regions. The first image is using Bridge Wall Max Overhang set to 100% and the second is using 50% and you can see that more of the lines are going to be printed using the bridge settings. For overhangs, I recommend setting Minimum Bridge Wall Length to zero as the wall line segments are likely to be very small. Feedback Required From You Please give it a go and share your experiences, all feedback is welcome (good and bad). You can either reply to this topic or for really bad news, please submit a github issue.
  20. Hi everyone, First time poster, but have been using Cura for about 8 months now. Seeing a weird result tonight where the Solid view of a model conflicts with the layered view of the model, and the actual physical print. I grabbed this print from Thingiverse: https://www.thingiverse.com/thing:2893747 I loaded the "walls.stl" in Cura (attached to this post). When I view the Solid View it shows the design as not having a roof (which also matches the original authors description of the design). The "ThingView" mode in Thingiverse also shows no roof. When I switch the view to Cura's Layer View, it generates a roof. The roof is substantial - enough that it creates 15-20 layers of infill !! The physical print also included a roof. Do you have any ideas about why the views would be so different? I've never seen that before in Cura. Cheers, Peter Walls.stl
  21. Hi guys, I was always happy to play with PLA on the Anet A8 until recently I printed some small parts in bad shape. As you see in the pictures, the bigger part(70mm length x 70mm width) has good quality but the small part with the same Cura setting( listed below ) gets some cracks and uneven surface. The major Cura settings are listed as follows: 1. layer height is 0.2mm; 2. wall thickness 0.8; 3. 100% infill density; 4. printing temperature is 220; 5. build plate temperature is 65; 6. printing speed is 30 and initial layer speed is 10; 7. regular fan speed is 70% and max is 90%. Could you help me find the reason why the smaller parts with the same Cura setting has bad quality? How to fix it? Thanks Jake
  22. Today I tried to add a new material in Cura (via Preferences, Configure Cura, Materials). I duplicated the Generic CPE and then started to change some settings: Display Name: PETG Brand: BrandXYZ Material Type: PETG (doesn't exist in Cura) and then, as soon as I leave the last field field, the material has gone, without any warning or message. Another material (ABS) is then selected. At first I didn't notice that this happened so I entered several other values, but I was altering the wrong material! Unfortunately there is no Cancel-button on this form so I wasn't really happy. So please UM/Cura-team, - add a Cancel-button to this form - support unknown materials OR give a clear warning before throwing away my entered data OR make the Material Type-box a selection box. Thanks!
  23. Good morning, I work for a local Makerspace where we do a lot of prototyping for new product ideas, and so far I have enjoyed the Ultimaker 3. Were looking to use some of our non-ultimaker material in some prototyping projects, and as capable as this >$4000 printer is, it seems top lack a basic feature? I can't seem to find anywhere how or where to input custom materials, like our Ultimaker 2+s can. The default profiles aren't always optimal (or sometimes just don't work) with different variations of a material. Our Nylon (PA 12) does not work very well with the Nylon profile, and requires tweaking every time we print with it. There has to be a better way?
  24. Hi, Here's a hot topic... let's see what people think. As a contributer to Cura, I am pleased that users can try out new features and provide feedback due to the regular releases of Cura. But not everyone wants to try out the latest and greatest features/bugs as they are actually more interested in stability. I use Cura to create parts for my business and so I understand very well people's requirements for a stable version of the software that you know will work (with whatever limitations it may have reliably). I use the development version of Cura and it does get broken but, for me, it is normally no hardship to rewind back to a working version. I appreciate that not everyone is in the position to do that. So I think that Ultimaker should give serious consideration to changing their Cura release regime so that those people who want stability can have it and those who want to live on the edge can do so. I can think of two examples of software products that allow users to choose between stability and new features: Ubuntu Linux - produces feature releases every 6 months and LTS (Long Term Support) releases every 2 years (I think, whatever, it's a long time). Google chrome browser - has 3 release branches (dev, beta and stable) stable still gets updated fairly frequently but not as much as the other branches. Personally, I strongly believe that Cura should be released using the LTS model, i.e. once an LTS release has occurred, only critical bug fixes will trigger a new release on that branch. The more frequent feature releases can then be the incubation environment for new features, etc. When new features and other changes have been proven to be sufficiently stable and worthwhile, they could be incorporated into the next LTS release. My overriding rational here is that the vast majority of users are more interested in stability and basic print quality than having new features. Please discuss politely. Cheers, Mark
  25. Hi everyone, today, for the first time I wanted to try to Support Blocker function available in Cura 3.3.1. The function, as is, works fine, however placement of the blocker cube is a nightmare. Consider an example when you do not want any PVA support in small horizontal through-hole, like this one: As I understand if I want to block the support I select the body of the object, then select "Support Blocker" and then click the red area visible on the picture above. Aaaaaand nothing happens, however after changing the camera view I find a very distant dot, far away from the printer workspace: If I'm very very precise with my mouse I can select them, then enter the 0,0,0 mm position in the Move menu and then use the blocker cube as intended. Am I doing something wrong? How should I select the area for support blocking? Or is it a Cura bug?
