  1. Bath interferometers. I have made about 20 of these for people who use them to test their telescope mirrors. They are amazingly accurate and can do better than a $40,000 Zygo PSI optical tester. These can test to almost 1/1000 of a wavelength of light although having the mirror within 1/10 of a wave is more than good enough. Basically anything in the photo you suspect is 3d printed - is 3d printed. The screwdriver is not and the tripod that holds it is not. Everything else plastic is 3d printed. Mostly PLA, some parts on the interferometer itself are nylon as they need to ben

  2. I am quite proud to announce that sometime this morning, someone was the 1,000,000th to download one of my plugins from the Marketplace! To celebrate, all my Cura plugins will be available today for the very special price of FREE! (oh, wait, they always are 😉). As always, some exciting updates are coming up.

  3. I have created a plugin that lets Cura access HID mouse devices such as the 3Dconnexion Spacemouse. It's called RawMouse because the plugin interfaces directly to the raw device without the aid/hinderance of an operating system driver. It's not a sophisticated all-singing, all-dancing interface, it simply converts the HID mouse commands into the equivalent 2D mouse commands. It has been (vaguely) tested on Linux and Windows 10 and it should also function on MacOS (10.13 upwards). For a quick install, unzip the latest RawMouse.zip from https://github.com/smartavionics/

  4. Hey guys, long time no see here. First of all, I'm happy that the Mark2 community is still alive (and kudos to @tinkergnome for doing the support work!) So, here's a small project which addresses one of the weaknesses of the S5 design: Prints which require good cooling, particularly with PLA and/or of smaller size, are really not among its specialties ... Printing with core1 shows even worse results than with core2 and walls facing left generally suffer more. There are two main reasons for this. First, introducing radial fans with the UM3 was a good idea b

  5. I was asked to implement the Schwarz P and Schwarz D TPMS infill patterns by a user who wishes to compare their properties with the already implemented Gyroid pattern. This I have just done and so I'm just letting people know in case anyone wants to give them a go. This is Schwarz P ("Primitive") and I don't think it is so good for general infill as it requires a lot of travels because each layer consists of a bunch of closed loops. This is Schwarz D ("Diamond") and, like Gyroid, each layer consists of wavy lines so it requires fewer travels.

  6. Somewhere around 10:00 AM this morning (CET), the total number of downloads of plugins I've published to the Marketplace crossed the 500.000 mark: Statistically, it is most likely that it was someone installing the OctoPrint Connection plugin, but I have no means to see exactly. I am fairly proud of reaching this milestone, less than 2 months after Ultimaker celebrated 1 million downloads from the Marketplace, which itself was only launched a year ago. I'll do my best to continue to improve your Cura workflow.

  8. Hello, Let's conclude this discussion. Ultimaker Cura is tailored for Ultimaker 3D printers and open to third party printers. We create the platform and keep that door open, but we are not responsible for profiles of other printers, for reasons mentioned above. Not every update requires a modification to a profile, but new features can in theory impact elements of a printer profile. That is why we lean so heavy on testing during the beta test. You can help identify existing bugs and improve the experience for yourself and your peers. In the meantime, we are happy that

  9. Indeed they didn't, because they don't release software at all. The cura installer is actually the only bit where a profile can get deleted, apart from a manual deletion from the interface. Cura will only ever delete a profile if you explicitly told it to do so. I don't have a low regard for third party printer users. Far from it. But we simply have far too much work on our plate as is. Cura is being developed by a relatively small team and being used by hundreds of thousands of users, using hundreds of different configurations. The only way how we could do something

  11. I was looking into a way to occasionally print Ninjaflex or other real flexible materials (85A) There's no way you'll be doing that reliable with a bowden setup (ok, I've seen people using oil in the bowden but nahhh), so I compared a quick and dirty direct drive conversion on an Ultimaker2 head (tested on my DIY GO) and on the ultimaker S5 **** first a warning, Ultimaker does NOT want you to open the S5, it contains an open style high voltage power supply, so it's DANGEROUS!!!, also the electronics can be damaged and I'm pretty sure you loose your warranty.

  12. Hello there, do you also love Cura but sometimes get lost in all its beautiful settings? In our knowledgebase on Ultimaker.com we have dedicated many articles explaining how those settings work. So if you find yourself wondering how a certain setting works or if you just want to learn more about what Cura can do, visit this link; Cura settings explained. We put a lot of effort in writing these guides so let us know what you think! Looking forward to hear from you!

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 was the last time I did something perfect, myself? Hmmm. Let's maybe cut each other a bit more slack and let the water flow off our collective backs a little. For those who celebrate Thanksgiving this weekend (as we do in Canada), then I hope there is something that inspires thanks in your life.

  15. Ultimaker Cura has hundreds of configurable slicing settings in custom mode. If you mouse hover over a particular setting, a description of what the setting does will appear. You can also search for a particular setting using the search bar to get what you need quickly and easily. In an upcoming release, we've also made each setting's description searchable for more ease-of-use. @ghostkeeper has also made a plugin that you can download from the Ultimaker Marketplace that adds even more description to each setting.

  16. Hello! You may have heard stories about glass plate having one side which brings you slightly better adhesion compared to the other side, or perhaps you have experienced this first hand yourself. Allow me to provide you with some background information and some instructions to figure out which side you should be printing on and which side you should use if you want to add an adhesion sheet. The difference is first introduced during production. When our glass plates are being made, near the end of the production line there is a hardening process. During the hardening pr

  17. In times of Corona and the call #stayathome, we thought we would become more self-sufficient to avoid shopping. So I had the following idea, where my Ultimaker S5 supported me a lot and, as always, provided me with very good services and results. You wouldn't believe how versatile such a 3D printer can be. But pictures say more than words: 1.) Set the bed temp to 27°C 2.) Put the bowl with the bread dough into the printer and let the dough rise for one hour 3.)

  18. 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

So, what do we have in store for you: With this launch we are also trying something new. We've created a short video where we inform you about a range of new features that are in Ultimaker Cura 4.7.

  20. We have the highest regard and appreciation for the community contributions, and we express this regularly. On the splash screen and almost every blog covering a Cura release. Regarding third party products, we do rely on either the users of a third party printer or the manufacturer to provide us with the machine settings and testing during the Beta period. We don't own or have the capacity to test, create or update all those third party profiles when we're working on a new version. We receive a profile, we check if it technically is correct and we add it. A new versi

  21. A user of my Cura builds asked about reducing the chance of resonance when printing areas of skin with short lines. I have therefore added a new setting "Avoid Frequency" that, when non-zero, specifies the resonant frequency to avoid. Skin, infill and support interface lines using the Lines and zig zag patterns that would be printed using hot end motion within +-/20% of that frequency will be slowed to move away from that frequency band. Here's an example showing the speed reductions in the narrow(er) skin regions... So if anyone uses a printer that has res

  24. Get our crap together? Excuse me? You're using an open source product, on hardware that we don't sell or support. We don't even have those third party printers nor the capacity (and desire) to actually test them. So if you want to prevent issues like that, pleas use the beta and report these issues during the beta. As you can see, i've managed to create a fix for this within a single hour of this being reported. We test Cura as much as we can, but we greatly focus on Ultimaker machines since 99% of the development of Cura is paid from the revenus of Ultimaker.

  25. Hi, First off i really don't think swearing is needed when asking for help, you are wanting help so be nice to them that want to help. The changes it means are any custom edits you have made to the profile settings, so any settings listed under the "Customized" part, so in the case above its your Printing Temperature (Extruder 1). I personally use it alot, because i edit my settings for supports and cooling so as i swap between profiles for differnet quality or filament types it keeps all my edited settings so i don't have to keep editing them all the time.

  26. I certainly cannot comment on all your findings as some would require to be a firmware dev. But this information here might help to understand why things are as they are atm. 1 - The printer is waiting for the heated bed to cool down. As soon as it is cold enough to touch you get the "confirm removal" button and can finish the process. The background here is a legal one: the machine has to be safe so removal should not be allowed if there is a risk to burn your fingers. Safety is part of professionalism - whether we like it or not in specific cases. You can speed it up on your

  27. @gmeardi If you can love the solution depends on how much you are willing to stretch 'easy', so here we go. Before working with the Ultimaker S5, I've never really put my mind to NFC technology, so there are very probably some gaps in my understanding. Most of what I've learned, I've deduced from comparing the data from different spools and with different amounts of remaining material. The rest I could fill in reading the relevant python code of the firmware after ssh-ing into the printer. As @Daid pointed out earlier, Ultimaker tried to implement NDEF records. Accordin

  31. 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

  32. 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

  34. Hi all, Today we've released another patch upgrade for the S-line printers - you can now download firmware 5.8.2. In this release we have introduced a loading error wizard for the Pro Bundle which catches errors whereby loading would have failed. The wizard provides the user with a chance to recover from this error. Read more about this wizard here : ultimaker.com/loadingwizard Furthermore, improvements to the NFC reading mean that the Pro Bundle should more often correctly read the filament type and material left.

  35. 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".

  36. 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

  38. I'm going to answer my own question about the NFC improvements and the Material Station. Prior to 5.8.2, getting the Material Station to read NFC codes was a real pain. It could take 8-10 tries to get it to work and it seldom worked the first time. I did a lot of loading and unloading with some filaments that were in the 8-10-try category this evening to test the improvements, and even added a filament the station hadn't seen before. Everything worked the first time.

  39. @gandy I came across your example scripts for creating and writing spools while trying to write my own tags for some 3rd party spools. I just wanted to say the scripts worked really well! (I ended up getting the ACR122U-A9 as you were using) I combined your 2 scripts together, and then wrote some extra modules and a qt interface on top so I could easily create new spools as needed or check on my existing spools. I also added a lookup function to determine the material from the guid by reading all the material xml files in both the user and system cura material directories.

With regards to Cura crashes, it would be best to submit an issue on the GitHub repo of Cura with log files attached. Otherwise the devs cannot debug your issue.

  50. I ran into the same problem. This did the trick, for me: Make sure there is no cura.exe process running, by looking in Task Manager (or just rebooting to be sure). Go into .../AppData/Roaming/cura/4.4 (or whatever version you are running) Delete cura.lock, if it is there. If it is not there, and Cura is not running, then this isn't the problem for you. There is no risk, at all, in deleting that file. It gets created at runtime and is really only valid while Cura is running. If it doesn't get deleted when Cura exits, it will cause the package manager to hang.
