  1. I loaded 5 different STL files, arranged them on the plate and printed them. Now I don't remember the file name of each model on the plate, and they look about the same with minor differences. When selecting a model, there is no information beside location and scale. Since there is an option to reload all models, all the file names must still be in there somewhere. It would be very helpfull if at least the filename was shown on the selected model or a "name" layer could be shown, displaying the filename on each model.
  2. I'm printing with the S5 and would like to print a single piece in 2 colors by switching between the 2 extruders at specific layers. Is there a plugin that exists to add these changes? I'd like to avoid dividing my model into mu ltiple pieces or doing manual filament changes if possible.
  3. I was thinking of if it would be possible to add more top/bottom layer patterns. It could be interesting to give a nice pattern on objects that the main face it's the bottom layer because the shiny/smooth result of the glass bed touching face. Something like this:
  4. Hi, I have always found the Tweak at Z plugin very useful, but I have always been wondering why there has newer been a option to change layer height in the plugin. Can anyone tell me if there is a technical reason why this has not been implemented? Now that the adaptive layers function in Cura is working fine, I would guess that it is possible to implement a manual function for changing layer height at a given Z-height. I do not believe I am the first person to find this useful, so I wonder if there is technical challenges stopping the implementation of this function? Best regards Robert
  5. Hi, is there any way to selectively increase the flow rate just for infill? I know you can change line widths for different features (infill, top/bottom, etc.), which is great, but with larger line widths for infill (and even with moderate print velocities and reduced print accelerations for infill) I'm a bit of infill underextrusion. (Print temperatures are more than sufficient) For that matter, being able to selectively increase the temperature for infill lines would be cool. I suppose this could be done with dual extruders (use a larger nozzle, extra flow multiplier, and higher temperature just for infill)...
  6. I often use ironing option to smooth PLA prints. Ironing using concentric pattern is never a good choice as it always either leaves a little elevated spot in the center or irons suboptimally. It's expected, maybe some fine tuning would help, but thresholds of values are too small to having it repeatable. This isn't an issue though. I would prefer a zig-zag pattern instead. However this pattern has an issue this post addresses. If applied on round or rectangular surface it works almost well. However if the surface is more complex some parts of it aren't covered with the pattern. It's a matter of an algorithm, more specifically probably a choice not to return to already ironed areas. But it nullifies the purpose of ironing. There would be several ways to mitigate this issue. Add an option to fill all space with zig-zags regardless of potential seams that can occur, or include another pattern that could fill irregular spaces with minimum number of returns (some space filling approach, maze like, Peano curve or Hilbert's maybe).
  7. I've found that using adaptable layers, faster infill and supports, thicker infill layers ect it can quickly get impossible to find a temperature that works well for everything since the rate it's being asked to extrude plastic can vary so wildly. Hot enough for the fast thick infill means strings and blobs on the surface. Cool enough for the fine surface means jams and under extrusion on the infill. I've set up auto temp so it can go up and down but it can only adjust so fast. So I was wondering if there is a way to smooth out the flow so the nozzle has a chance to heat/cool. Essentially when suddenly asked to deliver a lot more plastic it could slow the print right down so the actual volume of plastic remains similar. Then slowly speed up as the temperature rises. And before it has to deliver less it could slow back down as the nozzle cools in preparation. Does this exist already? Or if not could it work? (I couldn't find it from Googling but that could just be not knowing what to call it)
  8. Hello, I think I have found a bug in the way Cura scales the models. When slicing one of these objects found here: https://www.thingiverse.com/thing:2753230 I wanted to do an EUR version and tried to "scale X and Y to 99.57% and Z to 101.3%" However whenever doing that it scales also other Axis or ...welll... hard to explain - generally scales incorrect values/axis. Try by yourself. Tested on Cura 4.0 x64 for Windows and Cura 4.1 x64 Beta - the result is the same. I worked it around by scaling with the size in mm instead of % even though it updates the percents in incorrect places (different axis) too.
  9. Did anybody notice that Youmagine is completely covered in spam ?
  10. I am a cast glass artist and I have purchased a photograph with a standard license, which allows me to create a work of art with it and sell it. This photograph will be used to create a 3D model, a relief sculpture in wax, which will be re-formed into a boat shape, then cast in glass. The lithophane process in thingaverse provided just what I need to print the relief sculpture in wax. But I do not have the CC license thingaverse wants in order to publish and get to my .stl file so I can use it. So I have three questions, 1. Is there any way I can get to that.stl file in thingaverse without publishing? 2. Is there any other way to do the same thing? 2. Since the photo will change so much from its current form, do I even need to worry? Thank you in advance for any help you can give.
  11. Hi. I was wondering if there was a setting in cura for support layer height, and if there isn't if it could be implemented in the next update. Thanks!
  12. Hi Is there a way to tell Cura to put Tree Support in one place only and not on the whole of the model?
  13. Hello, I've been educating myself in Ultimaker Cura 3.6 by writing my own Plugin. At this point I've no problems and everything is working fine. I now decided to convert one file of my Plugin from .py to .pyd with Cython. Now Ultimaker does not even load this Plugin anymore, saying: 2019-04-05 14:46:01,337 - ERROR - [MainThread] UM.Logger.logException [88]: from . import J_Do_It_2 2019-04-05 14:46:01,337 - ERROR - [MainThread] UM.Logger.logException [88]: ImportError: cannot import name 'J_Do_It_2' Does Ultimaker Cura not support Plugins with precompiled/converted .pyd files?

  14. Application Version Cura 4.0 - Windows 10 Principal Problem When using different fillings for several models using the "Per Model Settings" tool, sometimes it does not place the filling inside the piece. For example, in the following image you can see how the configuration is to have 80% fill, 60% fill and 10% fill. In the first case I don't place any filling, in the next case, but not in the 10%. In this other example, make changes not so abrupt and reaching 40% I found this error again. This does not happen if I put this percentage without using "Per Model Settings", besides that I do the same in version 3.6 and I do not find this error. I don't know if with other "Per Model Settings" options have the same problem, but I would recommend reviewing them. Greetings and I look forward to version 4.1. CCR10S_S-Plugs.3mf
  15. When printing or ironing a top skin in zig zag or line mode, it will cover most of the area going one direction (say left to right) then come back and fill in some spots going right to left. this leaves a different appearance to those areas (see picture, bright and dark areas). I haven't found any way to control this. Could this be added? thanks
  16. UMS5 +CURA 3.6.0 Does anyone know if CURA can handle more than one model at on the build-plate but with only one touching? I have a part where I want to extrude the main body in one color of ToughPLA and then another section in a 2nd color of ToughPLA. My part will have the base model on the build-plate and the 2nd model centered over the first but at about 2mm above. The two models are designed such that they nest together, so there are not any gaps or voids. The issue I am having is that CURA will not let me move the 2nd model above the build-plate. Every time I try, it snaps the model back to Z0. I can work around this by having the void in the 1st continue through the model, but it results in much more of the 2nd material being used. I assume I'm missing something since the sample print included with my S5 seems to depict what I am trying.
  17. Hello Community I think I have a quite simple question but unfortunately no answer. Is it possibel in CURA 4.0 to modify the color in the mode "Preview" => "Line type" => "Color Scheme"? Currently the Top/Bottom-Layer is represented in a kind of light yellow. The infill is represented in let me say a kind of less light yellow color. As we are all aware about the fact that millions of colors are available I do not understand why this extremly similar colors have been choosen for representation by CURA. E.g. why not follow the PRUSA Slicer approach? I really looking forward for an answer. Kind regards, Carsten Schröder Horneburg/Germany Cura Approach: PRUSA Slicer Approach:
  18. Earlier, I began printing in PETG, and my first prints got successively better, till little parts of the prints I made were clear enough for me to hold against a screen and see the details through it! but no more. I was printing little 1cm cubes, and I began noticing that the issue lies in extrusion...lines? Essentially, little bubbles between the extrusion lines were left behind, even after dialing in my settings to the best of my ability. I believe ironing may be the solution here, but therein lies the issue. Cura only supports ironing on exposed upper surfaces. I believe it should be an option, and not hard to add a little check box to "iron everything". it should come with a warning that it will slow down prints immensely, but after spending 3 hours on a 1cm cube in an attempt to get it a little clearer, I think the feature can stand on its own. I'm not sure it will make things clerar, but I'd say there's a decent chance, and some extra heating on the top of every layer may actually help strengthen prints by removing fracture points and ensuring better layer adhesion, in any case. another option would be the ability to list which layers should be ironed and a checkbox for whether to include the entire layer or just exposed faces. I know a few people that wanted to iron only a couple layers.
  19. I think it could be practical to be able to change the grid on the viewer to match a grid on the actual bed. I am thinking of lining up a grid on my bed to help place parts/apply glue, but the current grid in the viewer is too fine masked. If it was possible to add an image that would be very helpful, or even just being able to adjust the grid distance. 1cm is a bit too fine grained. Perhaps a possibility to make every n-th line a different color/thicher line? Then it would be possible to mark out say a 3cm or 5cm grid on both the screen and the actual bed.
  20. Hello I am using this code on Cmd CuraEngine.exe slice -v -j "C:\Program Files\Ultimaker Cura 3.0\resources\definitions\ultimaker3.def.json" -l "C:\Users\jerome.christ\Desktop\cura\screw.stl" -o "C:\Users\jerome.christ\Desktop\cura\output.gcode" Code working fine but I can't edit infill percent any idea ?
  21. Hello everyone, i am interested in making concrete cast using PLA mold/template, but I have concern with the cast removal, do you know any lubricants to be used? What would be other challenges in doing so?
  22. The motivating problem: I have recently experienced frustrating print failure at near-completion of a large, tall 2-color PLA print on a Creality CR-X (2 extruders, 1 hotend)—the problem is that even with a large prime tower footprint, when it gets tall (200-300mm), the torque from the printing pries the prime tower loose while adding layers. Also, it is extremely wasteful of material. The solution (a new feature): It occurred to me that the prime tower would be completely unnecessary if the G-code would instruct the machine to perform filament switch before finishing one color so as to push the leftovers out on that same color, and then prime the next color into the interior of the part, for example fill or inner walls. In this way, the primings are integral to the object being printed, resulting in zero waste and more robust printing. This feature could be implemented in Cura with perhaps a checkbox and 2 parameters (the length to continue extruding after filament change and the volume to prime, which is already a parameter) and some programming to sequence the operations near a filament change. There may also be the need for a feature that warns the user if there is not enough infill or inner wall to handle the desired priming volume. Best Regards and thanks for the sweet software! Gian
  23. Hi, ultimaker team and members. Is it possible to have the leap frog bolt pro added to the list of supported 3rd party printers? At the moment I have an Ultimaker 3 which runs very well with Cura. After including a leap frog bolt pro to my fleet of printers I have noticed that simplify 3D has very limited options to control how the print is done. For example, the support structures, it struggles to produce complex support or organic objects. More over setting like acceleration and print temp control and first layer perimeters are very important and is not possible with simplify 3D. On the other hand, Is it possible to add this machine as a custom printer. I understand that most printers run using firmware, some is unique to each printer. How would I go about programming cura to run the printer this way? Its clearly something I have never done before..... If any one can help I would be hugely great full!
  24. My printer's firmware has heating commands built into the Z home. When you do a Z home, it heats both extruders to 120C before actually homing, so that any blob on the nozzle would be soft enough not to mess things up. This interferes with Cura's initial heat code, which goes before the starting gcode from the printer. What happens is that Cura heats things up to the set point, the Z home in the starting code then takes the temperature down to 120, and then I have to heat it up again. It would be nice if you could either (a) turn off the initial heating gcode (and then add it back in as part of the startup gcode), or specify special gcode to run before those initial heating commands. I can work around it by taking the G28 out of my startup gcode and making sure I manually home all before each print, but that's a pain. If anyone knows of a better workaround, I'd like to hear it.
  25. I've been using Cura for a little while, I ran into an issue recently where the tool just stopped running. It would attempt to launch, show the splash image then an empty window that would just hang. Tried restarting, uninstalling, reinstalling, nothing worked. Luckily I found a way to fix it... I have a laptop dock with 2 attached monitors. The only different thing (to my knowledge) was I used one of the attached monitors for the first time and it kept trying to launch on that secondary screen. Which It was having trouble doing. I unlplugged the dock and used just with the screen on the laptop. And it opened up! I attached the log of a clean install of cura showing the symptom below if it helps resolve the bug permanently. Hope that helps someone who might've had the same issue I did. It might be display related, unplug all secondary monitors and see if that helps. Cheers. _run1_cura.log
