  1. Hi All, Not sure where to post suggestions, so I'll leave this here - please let me know if it belongs somewhere else. I'd like to suggest a setting that allows the travel speed to decrease (user settable) in areas where the overhang gets above a certain value. I found with my printer, if I left the travel speed at the usual setting (40-50mm/sec) then my overhang tests would only get about 50-55 deg, but if I dropped the speed to about 10mm/s then I could get results much closer to 75-80deg overhang meaning I could print much more complex parts with less support material. Unfortunately printing a whole model (especially a large one) at 10mm/s is out of the question... So it would be super cool if Cura could allow me to reduce the travel speed immediately above areas (for say... 4 or 5 layers) that have overhangs above a certain value in much the same way as supports are added now if overhangs are over a certain value... Hope I'm not the only one who'd find this helpful. Regards
  2. I've attached my new bath knob. Permissive commons license and already on thingiverse. I was watching the print (3D printers can be so mesmerizing on a lazy Saturday)... and I think I detected one place where Cura can do better (although I don't know if I know where to twiddle... is this possible with a plugin? I'm happy to roll up my sleaves if I'm not wasting my time. I figure this is pretty common. The hole narrows in the middle. It's wider on both sizes and there are good reasons not to fillet (basically... the screw supplied with the original part wouldn't fit properly for one). Your first reaction is that supports would make it print 100% successfully. I'd say supports are hard to remove in there... but also, the current behavior is so close ... it just seems cura can do a tad better... If you print the knob with the outside surface down (seems the sensible way), the hole starts at 12mm and narrows to 5.5mm (I know 'cause I made it). On the first layer of bridging, it starts fine ... going across from the edge of the circule out until it is printing the part of the smaller circle that isn't a contiguous bridge... which continues until it is again. This dumps that non-contiguous material down the hole and leaves two side bits almost-ok. On the next pass, we almost get it right where the 2nd bridge layer is 90 degrees to the first ... and you get the square part of the circle-square being almost right... but still, on this pass, more material down the chute. If you were amazingly smart about this, I'd imagine the best way would be to print this as a series of tangents to the inside circle that began and ended on the solid outside circle. If you were less smart about it, printing the two 90 degree edge bits on the first pass, you might not be dumping the circular inner walls down the hole. Thoughts? BathKnob v6.stl
  3. Hello, I would like to submit the following features for a future Cura release: 1. The ability to rename and/or the ability to annotate cloud back-up files. It would be great to be able to include some indication of what's different about a given back-up. 2. The ability to override the default file name for generated gcode based on a template; for example: 'cura-S4_' + [filename] + '_' + [mmdd] = 'cura-S4_MyModel_0814.gcode'. It would be nice to insert the date pattern, have the ability to create an increment number for duplicate files and/or change the prefix of a file. Cura is awesome - keep up the great work! Thanks, Rich.

    Manual USB Connect Button

    Hello, I sometimes have the problem, that Cura doesn't automatically connect to my Anet A6 (with Marlin 1.1.9) so that I have to replug the USB cable or restart Cura many times until I get it working. Is there any chance that there could be a "Connect to Printer" button so that it manually creates a connection via USB? Best Regards, MrMinemeet
  6. Good morning my extension perfectly working in 3.2 on Prusa I3 mendel printer and developed in Python as required with all files. perfectly working in 3.2 crashes at first command in 3.3 and 3.4 BedlevelPlugin.zip
  7. We have an Ultimaker 3 - 3D Printer in our office. Since it is quite noisy we normally do the prints for prototyping overnight. Is there a possible to time shedule prints? At the moment I prepare the prints, start the print and press pause. When I leave the office I often forget to unpause the print.
  8. I originally posted these requests over on the Cura Lulzbot Edition Workboard as I'm a Taz 6 user, but figured it might be better to go to the source. Option 1: Define Model Print Order When printing multiple duplicate parts, several efficiency issues arise as objects are often printed in a non-uniform sequence requiring additional unnecessary travel between models. This effect is particularly noticeable when printing an array of duplicate objects which require supports. Support layers for each duplicate object are printed prior to printing corresponding layers of each object which effectively doubles the travel time for each layer of the array. Experimentation with the order in which models are duplicated or added to the build plate within Cura seems to have no noticeable bearing on the sequence in which the models are printed. Model grouping also does not appear to affect model print order. Existing potential options to influence this process including the “one at a time” and “all at once” options as well as z-seam alignment customizations produce inconsistent results. An option to manually define the sequence in which models are printed could solve this issue. In my experience, even on seemingly simple arrays of duplicated objects, Cura often prints objects in an order that increases the number of unnecessary moves. I've included 2 screenshots of an array of parts where I have overlaid the order in which the parts are printed (actual print order vs. desired). Beginning in the bottom left corner User Specified Z Seam Alignment where X=0 and Y=0), the actual print order skips a model altogether and then backtracks to complete it which does not seem to be the most efficient path. Perhaps I'm doing something wrong, but I can't figure out why Cura has decided that this is the preferred sequence for this particular array. It would be preferable if the order in which objects are printed is displayed and editable to prevent this from happening. This could also come in handy for those wanting to print a "priming" object. I've seen several inquiries on various message boards where folks have requested the ability to print a skirt for priming and a brim for build plate adhesion. When printing with a brim only, sometimes extruded filament has cooled slightly when it first comes out of the nozzle and does not promptly adhere to the build plate. When it eventually sticks, the cooled string of filament may have been dragged across the bottom surface area where the object will be printed. This can result in issues with first layer quality. To circumvent this and minimize the need to babysit the first layer, I've attempted to print a "priming object" first. However, since print order of different objects cannot be manually defined, it's luck of the draw as to whether or not the "priming object" actually prints first. Option 2: Uniform Tool-path Cloning When a model is duplicated multiple times models are often sliced in a way such that the path of the extruder is not identical for each duplicated part. This results in inconsistency in surface finish between models. Manual adjustment of Z-seam alignment settings can be used to influence the starting position of the extruder for each model in the array but does not guarantee identical tool-path travel for each layer. An option to clone the tool-path relative to the model would provide greatly enhanced surface finish consistency between duplicate models. Currently, in order to ensure that 10 objects are virtually identical, the same object must be printed in 10 separate jobs which requires start-up and cool-down time for each job as well as time for part removal. Even if the additional tool path travel adds 5-7 minutes per print job for an array of 10 parts, it would save time in not having to run the start-up and cool-down sequence for 10 different parts. The integrated cost savings over time of reducing start-up, cool-down, and part removal labor could be significant. Most importantly, tool path cloning ensures identical surface finish and structural strength between parts without having to run multiple print jobs. This is particularly valuable to small businesses who may not have the luxury of running multiple machines. Option 3: Per Model Settings – Build Plate Adhesion An option to manually select build plate adhesion on a per model basis would be beneficial in printing multiples of different models in a single print job where each model may require unique brim or raft settings would be beneficial in improving efficiency. I welcome any suggestion which might help to achieve the desired result with Cura's existing features.
  9. Hello all! I work as volunteer at CoderDojo in the Netherlands, Alphen aan den Rijn and we teach kids to program. I recently started teaching kids how to 3D Model, and they REALLY liked it! As most of you might know, 3D Modeling is fun, but it isn't as educational as printing the object in real life and learning from it's flaws. Since CoderDojo is a non-profit organisation, we don't get money from the CoderDojo Foundation but have to get it ourself. That's why I made a GoFundMe page to get money for a nice 3D Printer. I very much hope posting it here would get some attentions so we can teach kids the fundamentals of 3D Printing. If you want to donate, you can do that here: https://www.gofundme.com/teaching-children-3d-print Your money could really help kids to get an understanding of how these technologies work! Thanks in advance, The CoderDojo Alphen aan den Rijn team!
  10. 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!

    Cura s/w...Wishlist item!!!

    Wish Cura would import models in a saved project file in the same X/Y/Z locations. Just like it does when you open the file as a project. If you just click import models they are scattered randomly on the build plate again and one must adjust their locations all over again. Rick...
  12. I was wondering if there is a way to insert custom GCode for each different filament in cura? It doesn't appear that there is an option to do it in default cura, but are there any plugins that can do it? The reason is I would like to use linear advance, but different types of filament (PLA, PETG, Flexible) require different values for linear advance.
  13. Hello, I just realized something, which illustrates a bit the difference of thinking between software engineers and coders and everyday folks: for the latter, 0 is a valid value, like 1 or 2 or pi or whatever, for the formers, 0 is usually used as an absence of value, meaning that if you input 0 in a field, then it tells the program to not execute whatever instruction is linked to that field, and move to the next instruction. I was trying to help @4instudent with his Breakaway gap problem and realized that, when you input 0 in the 'Support Roof Line Distance' field, CURA interprets that as 'No support roof line needed' and creates a massive gap between the support and the bottom of the overhang because it doesn't create any support roof despite the option being checked, while what we wanted by inputting that value was 'No distance between the roof of the support and the bottom of the overhang, stick them together', the goal being to have the smoothest surface finish possible. I haven't checked all parameters, but I'm sure there are many other examples of the 0 being understood as a 'null' answer instead of a 0 distance. Which is very confusing to the layman who has no knowledge of coding, and very frustrating even if you know the source of the problem because you have to fumble around with small values like 0.01 and hope it doesn't lead to CURA being confused because your printing profile is at 0.2 or something. Could that be changed so that all the fields where the user can input a number, especially on 'distance' stuff, the 0 is read as '0 distance' instead of 'no value'? And, perhaps, put something else to mean 'no value', like leaving the field blank or using a sign like / or something? Thanks

    Estimated Time Algorithm

    I have noticed that print times are often way off of actual print times. I use ~v3.0.0 with a Printrbot Simple Pro w/heated bed, if it matters. Almost all of my prints take about 30-40% longer than the estimated print time. I understand that estimating the print time is difficult because of lots of factors involved in printing. What is the algorithm that calculates this print time?
  15. I wish the mouse view controls worked like FreeCAD. The right click for rotation is very awkward to use. In FreeCAD the view controls are: SHIFT + Mouse Move (no button click) to pan view ALT + Mouse Move (no button click) to rotate view It seems very intuitive to just hold either the CTRL or ALT key and move the mouse to pan and rotate the camera view. On Windows 10 without a mouse, Shift+Click pans and Right+Click rotates. The CTRL+Click does nothing. A weird mix of mouse and touchpad control.
  16. It would be nice if it were possible to disable temperature control for the nozzle, similar to how it is with the bed. I'm using OctoPrint, and I preheat the nozzle - and sometimes I like to try different temperatures without having to re-slice the model, or send custom g-code in-between. I seem to remember that it was possible in previous versions (i.e. old Cura), and there was a discusson on GitHub about it, where it was said that there is a setting somewhere for that - I didn't find it, though, so maybe it's in the underlying json files? In any case, I think it would be useful if the temperature setting for the nozzle worked the same way as for the bed.
  17. Hi, When I print ABS the very first layers are not getting stick so well to the bed an causing a lot of mess. Almost every print I need to clean the excess layers with tweezers from the nozzle, which is not very convenient. In Simplify3D there's an option to enable both Brim and Skirt adhesion together. I would like to know if it's also can be done in Cura, and if not, will be nice to see it implemented into the app. That way you can clean your nozzle (or hope it will get cleaned somehow by itself) before the brim starts to print. Thanks.

    Estimated time with Nylon

    I'm new to this so bear with me. Cura estimated my print time at 3.5 hours with Nylon and 30 minutes into the print (Ultimaker 2+) the machine is saying 30 hours left. I'm sure I have a setting off somewhere, any ideas? Also, when choosing the material on the printer it didn't give me the option of Nylon? Any idea why and what I can do about this? I've only had this printer for about a week, got it pre-owned and still trying to figure out what I'm doing.
  19. 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.
  20. I find it hard to keep track of my multiple 3d printers. I would like to be able to also use all of my profiles and machine settings on multiple computers so I am not limited to a single computer.
  21. Hello, I am interested in a tool that imports gcode and saves the rendered visualization as a stl file. Is this possible? If it is not, what is the data structure behind the current gcode viewer plug in? Thanks!
  22. I want to do something, perhaps it is impossible with Cura. I am printing a structural part and strength to weight is important. Let's say it is a motor mount plate and have 7 bolt holes. Currently I find I need to print it with 2mm walls and 2mm top and bottom thickness then 40% infill and the part is strong enough. This works but I see a way it could be lighter and stronger. Walls are printed with all the plastic put down in parallel to the outside edge but I can only print walls along the edges. It would be very good if I could make "walls" in the interior of the part. Here are two use cases: I would like to have "walls" radiating from a bolt hole to spread the stress out in to the skin Cura makes a wall around the hole but the surface area of the outside is not enough to transfer the stress to the infill. Interior walls in a spoke pattern would make the hole stronger and I could make a truss design of thick "walls" that interconnect the bolt holes. This way the stress is carried by 100% solid "beams" that are surrounded by a light 25% infill. Lacking the ability to make these I must resort to higher infill even in sections of the part that are lightly loaded. Here is how I might try doing this now... In my CAD system (I use Fusion 360) I might make the part as I do now as a solid body then I make a second version of the same part but this version lacks the skin has ONLY the internal beams that interconnect the bolt holes with a truss frame made of triangles. SO I make an normal part and the same part again but as a skeleton truss. Then I print in Cura 3.2 I use the second version of the part to modify the infill percent. I set the infill for this to 100%. So now I have beams made of 100% solid infill inside a much lighter structure and my overall strength to weight is better Problem: The "beams" are made of 45% crossed infill lines. it would be MUCH stronger if the beams where printed like walls with all the plastic printed parallel If this is not 100% clear think of steel reenforced concrete. I want to print the steel bars the same way as walls are printed and I want to use low-percentage infill where the concrete would be. Perhaps this is something Cura will never be able to do, or perhaps I can use some tricks with my STL files to trick Cura into making "walls" inside the part I'm printing. Or perhaps there is another slicer that is better for making structural parts?
  23. Hey guys, it has been a while since the release of Ultimaker 3 what do you think can we expect a new 3d Printer in the upcoming weeks or months maybe an Ultimaker 4 ?

    Initial Layer Nozzle Temp

    There is no G-code generated in either the startup G-Code or the actual generated G-Code to set nozzle temperature to a different setting on initial layer. I am using Taz 6 machine and VP PLA profile now. I haven't looked at any other profiles yet. I would assume it would be consistent throughout though.
  25. Hello all, I've been printing with PLA/PVA for some time now, and the order at which Cura decides to print the "helpers" is somewhat affecting my print quality. What happens is that the first layer of my supports goes down, but due to not being primed yet is somewhat spotty and does not always stick. After a second it continues to print correctly, but the strands from the initial period can be dragged into the print area by this point. After that the prime tower prints splendidly. If anything, I would prefer the prime tower's brim to be stringy and reduce the bottom surface quality than the actual print. There does not seem to be a setting for this at the moment. Any chance this will be implemented? -Feo
