  1. When things are mission critical it's good to have tools you can count on, the knowledge to use them correctly, and the inner motivation to do your best. I would like to thank everyone here for helping me to understand at least a little bit about 3d printing and Cura. Zits were absolutely not acceptable and there aren't any. Sliced with 4.8beta. When I go to a costume party as James Bond, I go as James Bond. I'll have that shaken. Not stirred. Any comments regarding the fact that the glass looks more like a c

  3. I'm working on a plugin that wraps FormerLurker's command line version of the ArcWelder plugin originally developed for OctoPrint. The plugin attempts to reduce stutter by simplifying gcode. It analyses subsequent G0 or G1 movements that make up arcs and replaces these sequences with G2 or G3 lines. Gcode containing these arcs may or may not print well on your printer, depending on the type of controller and the configuration of the firmware. For more information about ArcWelder, read the description of the original plugin, and the discussion of realworld results. Gcode before

  4. So, I wanted to mention two changes to Arc Welder: 1. Vase Mode (3D arcs) seems to be working well so far. I've printed several, and haven't had any issues However, I'd still love to have a few testers if anyone is interested. Here is a link to the original feature request. 2. I added two new settings that enable Firmware Compensation for printers that do not have all of the goodies in Marlin 2, like MIN_ARC_SEGMENTS. Typically these printers have only one real arc interpolation adjustment: MM_PER_ARC_SEGMENT, which is typically set to 1mm. This is producing the flat edg

  5. Introduction Marco Polo, Christopher Columbus, Vasco da Gama, Amerigo Vespucci, James Cook. What do they all have in common, and what could they possibly be doing in a post related to 3D Printing and Generative Design? The obvious answer to what they have in common is that they were all explorers, many of them from an era known as The Age of Discovery. The reason they relate to this post is that Generative Design has been created for “design explorers” and it provides a method for navigating a route through to the discovery of the kind of design outcomes the like of whi

  6. Hi all, We've released a small update for the Ultimaker 3. You can upgrade to 5.2.16 as of today. This gives the Ultimaker 3 some more functionality within the Digital Factory. Release notes: · Digital Factory integration. Print jobs sent via cloud show print job preview images in the Digital Factory. Printer discovery including connection, cancelling, and removal have been made more robust · Digital Factory functionality. The Ultimaker 3 will be able to start, stop, pause, and resume print jobs remotely · Updated UI elements

  8. Yes, that was a bad experience. As Longtoke points out, it wasn't the fault of Cura. When you push the "Home" button, Cura sends the command "G28" to the printer and that is all it does. That G28 is interpreted by the firmware in the printer as "home all axis" and the printer starts the axis motors and moves the print head to the "0" endstops of the X, the Y, and the Z axis. The speed that the motors run at is also set within the firmware and Cura cannot effect the homing speed. It is then each endstop switch's job to inform the firmware "OK you can stop the motor now".

  9. While I get you're upset at your printer being damaged, you've incorrectly and unfairly attributed it to Cura... Firstly, the Tronxy you mention is a DIY kit printer, that takes some experience to correctly assemble, while having several design flaws that leave the door open to all sorts of issues. To quote one of the reviews I've just endured "My testing, however, was a long and frustrating experience due to a range of poor design decisions on this printer." And another quote "I think with a total overhaul by an experienced owner, this thing could really s

  10. Mmmmm, weird. This is either a partial clog that incidentally happened at the same time you've switch to 4.8, or an error when importing the profile. Check the filament size, because it looks like you have 2.85 instead of 1.75 in the machine settings. If you still have 4.7 installed try to print something small sliced with 4.7, the typical x,y,z cube for instance. If it prints ok, it's the filament size in 4.8. If it prints all wrong, clog Or who knows

  11. As the owner of two UM2+, I find it admirable that Ultimaker is improving their older models instead of just leaving them in the dust, lol. Any chance of making a retrofit kit to make older UM2's compatible with the UM Digital Workflow?

  12. So, I made an executive decision and renamed allow---z-axis-changes to --allow-3d-arcs. I figure that's easier to understand, and better to do it now than later. The artifacts should be rebuilding as we speak. Also, there is no raspberry pi console app in case anyone is wondering. I can build one, but still working to get a self hosted runner so that it's automatic.

  14. I'm confused as to why the 2+ is replaced by the 2+ Connect without an upgrade option for current owners. If this is true, then I'm out. I'll keep using my Ultimaker 2+ until it dies, but I'm not buying anymore Ultimaker products. I bought Ultimaker as upgradability was in the sprit of their products. Make it upgradable and let me keep this printer current or I can jump to a manufacturer who does.

  16. What you want is an infill pattern. No walls, no floor, no roof. Bring in a 25mm calibration cube. Use the Scale tool, but use the absolute numbers. Make it .4 thick and set it on the build plate. X and Y can be whatever you want. Layer height .2 Walls 0 Top and bottom 0 a bunch of other 0's Infill = lines Infill line distance = .8 Infill line direction = [0,90] Connect Infill Lines = False Infill Overlap % = 0 I think I would put a pause in between layers to insure that the first layer is hardened before running the nozzle back

  19. I know what you mean and the reason is, that the line width is very small, therefore it is not printed by default. But there are several options, not sure which one is responsible for that, but try: Filter Out Tiny Gaps -> unchecked Compensate Wall Overlaps And this could also help, when you print the outer wall before inner wall: Outer before Inner Walls Can you upload your STL or project file here, then we can also check it.

  20. First I should warn you that there are something like 100 machine settings that aren't shown in these dialogs unfortunately. You can include CAD files of your printer to make it prettier in the GUI for example. But it should be enough to get good prints for most printers. Also document what you did well because sometimes when you upgrade Cura (rarely) you get messed up profiles and the solution is to blow away all user files (like printer settings). Next, "creatware" is a fork of an older version of Cura. Cura version 15.X I think (15 refers to 2015). Cura 2.X came out that ye

  23. Sorry to hear so. It made sense to enable an option to upgrade an UM2 to an UM2+, or an UMO to an UMO+ because 'only' a few essential components were renewed. But the idea of upgrading an UM2+ to an UM2C was really pushing the boundaries of a reasonable product. And honestly, we felt it wasn't. It would create too many complexities, and it could never be a 'plug & play-upgrade'. If you rather have a DIY printer, there are plenty of options out there. The philosophy of upgrading our products is still very much alive though. Take a look at the firmware, which is updated frequent

Le problème vient plus surement de Sketchup que de CURA, explications : Retour aux sources. Avant de parler de Sketchup et de CURA on va parler STL.

  27. This is the wrong replacement pattern. Use this and Cura will not have to prepend its own preheat sequence for your extruder: M109 S{material_print_temperature} Similarly, include this to stop Cura from having to preheat the bed for you: M190 S{material_bed_temperature}

  28. And there is also a different Z stage. All things considered, where it made sense to enable an upgrade from UM2 to an UM2+, upgrading to an UM2+C doesn't make sense. It would have been really cool though, but unfortunately not possible. As mentioned, even the frame would need to be modified.

  29. Maybe service is just expensive and that is why chinese printers are so cheap. Just something to consider 😉 Anyhow, I also need my house to be painted. Why haven't you done so already!? I don't want to pay an actual painter to do it, because it's really expensive! All joking aside; You can just post issues on github. We will have a look at it. We can't guarantee that we will be able to fix it, because we always get more issues than we can handle. In some cases we simply can't reproduce the issue, which also makes it really hard for us to fix it (since we then don't even know where to sta

  30. Thank you for sharing your message and wild assumptions. If you want to get in touch with us you can do so via our community, Github or our ticket support system. If you decide to go for any of these routes, I would like to ask you to pay attention to your tone of voice when you're asking for help from people who have no obligation to help you. We are willing to help though, all users of Cura, regardless if you have an Ultimaker or not. Asking nicely helps. We're all just people.

  31. I finally converted my printer to DXU, but I am not using the original DXU print head, instead, I make use of the original head with modification, so that I can keep using the metal parts. I found this modification design from Chat room, however, the author only released the STL files and some them seems not work well. Therefore, I based on the original head dimension and reference to the STL file, I redraw all of them with Solidwork, modified some key area, attached the photos of my build as well as the parts photo exported from Solidwork. This head now used for over 100 hours

  32. You'll be happy to hear then that an upcoming firmware release will allow you to enable a firewall, blocking all incoming traffic from the local network. This is full, 100%, network security, whereas passwords are definitely not. By enabling this firewall, users are forced to print either via USB (physical security can prevent access to this if needed), or by using the Digital Factory, which has full user management and access management in place (especially if you're a company on an Ultimaker Essentials subscription). So we take security very seriously and are doing continuous imp

Flower model by 4frika: https://www.thingiverse.com/thing:1440472 I found the bowl on ScanTheWorld; I really want to take some more pictures of it from the side.

  36. That is a really bad model. In addition to not being watertight, it has numerous surfaces that don't fit right. I tried to do something with it in MeshMixer but I don't know that software very well although I made some progress. The way your model is now it will not slice and won't print.

  37. Oui, c'est ça : le contrôle se fait sur CURA MAIS en fonction de la valeur de référence sur la machine (consigne). J'expliquerais plutôt les choses de la manières suivante afin que ce soit plus clair : Si tu as un profil matériau sur ton UM2 dont la valeur pour les ventilos est fixée à 100 % comme pour du PLA de base il va se passer la chose suivante : si dans CURA tu définis la valeur pour les ventilos à 90 %, tu auras sur ton UM2 90% de 100% donc 90%. Par contre, si la valeur côté UM2 est fixée à 50 %, si tu mets 50 % côté CURA, tu auras effectivement 25 % sur la machine : 50 % de 5

  38. Yeah sure, this is one of the first large prints I did. It's a battery enclosure for my e-bike, it fits 39 18650 lithium-ion cells arranged in a 13S3P configuration. I had some trouble with my T10 (10mm) leadscrews wobbling which lead to the z wobble artifacts you might be able to see in the pictures. I've since upgraded to 12mm ballscrews and they have eliminated that problem.

  41. There are several issues with your STL file. It is not watertight, so the object is "open" somewhere, the faces are not closed/watertight. It is possible but not the best solution to use Blender for modeling for 3D printing. Better you use a CAD software like Fusion360, Tinkercad, Onsape, etc. They are free or free for non commercial usage. If you still want to use Blender search YouTube how to model for 3D printing and what is important. I don't use Blender so I cannot give you some advices. If you want to rescue your current model you could try if a STL

  42. Sieht zwar schlimm aus, sollte sich aber beheben lassen, da du beim UM2 alles gut zerlegen kannst. Ich würde folgendermaßen vorgehen: Beide Lüfter oben abschrauben Metallblende abschrauben (2 Schrauben links und 2 rechts) Falls das nicht geht wegen dem Filament, dann mit einer Heißluftpistole das Material erweichen. Das sollte es fast schon gewesen sein, wenn die Düse oder der Olsson Block auch betroffen ist, dann eventuell noch weiter zerlegen oder du bekommst es auch im montierten Zustand weg. Dazu eventuell die Düse aufheizen. Ansonsten mach einfa

  47. I have personally made some little anti-vibration feet for my S5 now because its on a wood desk so hopefully it will take out some the vibration and sound when printer is in use, more so because i have 2 s5 side by side printing. Best to use a TPU filament with around 50% infill, have added the stl files below for both right and left hand feet. It also gives about 6mm of extra height under the printer what gives better air flow for the fan under it. Or like i do i store the 2nd glass build plate under the printer. Body1.stl Body2.stl
