  1. Just wanted to thank Ultimaker (and maybe brag a little bit 😁 ) I recorded some time lapse video of printing some interesting structures on my Ultimaker 3ex. My company used it in a video on some work we did where you can see my little UM3 working away. https://www.siemens.com/global/en/company/innovation/inventors/additive-manufacturing-computer-aided-design.html Jump to about 4:15. In any case, its a nice product for use in research. Props to the Ultimaker folks. Also, props to those that help me out here in the community from time to time.
  2. @bagel-orb, @ghostkeeper and @burtoogle in case any of you have a second for these curaengine questions 🙂
  3. curaengine works at the command line. So you should go to a command prompt and run it from there. It sounds like you might be double clicking on it in windows. In this case, it would cmd would run, curaengine would run, see you didn't provide any command line options, and exit the cmd window.
  4. Hi all, I need some suggestions and help on using Curaengine. I want to use Curaengine for some backend and batch work. I've got it built ok. Poking around github, I've not found good documentation beyond what you can do from the command line. Here are my questions: 1. I have my own front end. I can call curaengine.exe from the command line but I suspect using it as a server is better since this is what cura does.. If so, where can I find information on calling curaengine running as a server? Can I keep it running for each new file I want to slice? 2. I have 3MF files. I see the command line wants STL. Is there way to pass it 3MF? If Cura does some pre-processing before sending the mesh to curaengine, I can do that too but an example or URL pointing to some code would be helpful (I have other applications using 3MF so I'm fine extracting the data). 3. I want to access the 2D polygons created in slicing for some special analysis. I have no problem hacking the C++ curaengine code. It would be great if someone out there already familiar with the code could point me to the right source files for a bit of hacking (it is just research 🙂 ) Thanks!
  5. My loyal Ultimaker 3ex, we will call her Edith👵, randomly just stops printing every few hours🕑. It used to be infrequent but only the shortest of prints has worked the last few weeks. She is quite old with a warranty that is long expired. I'm handy enough * to take it apart and replace parts. I suspect it is the Lime2 board. Poor Edith will be in the middle of a print and just stop. The menu keeps saying "Pause" and "tune" but "pause" does nothing. I can go to "tune" but no options work. Anyone else see anything like this? Surely, Edith has sisters. Edith is set up for development mode and when she stops, I can no longer ssh in. The web pages she serves out is gone too so there is no log to look at. This also has me thinking it is the Lime2 board as it runs this stuff. The room is a cool 65 degrees (65 -32 * 5 /9 Celsius) but I suspect it is overheating. I don't think it is the power but I do live in a third world country (New Jersey). P.S. Sorry for the poor humor but this seems like a really boring post. * If women don't find you handsome, they should at least find you handy!
  6. I let it run for about 45 minutes and it finally finished. So it is not hung, just s l o w w w w . I rotated it by 30 degrees but still had the problem. Also tried 3MF (just facets, no extensions) with the same problem. You are right about it being overly precise. I just hate tuning my STLs for where it is going to be used and Cura generally deals with it ok (just not today 😞 ) But it didn't crash and I did finally get some gcode so that is good 🙂
  7. I have a model that when I go to slice it, it just hangs with the CPU pegged at 100% at about 1.3 Gig of memory used. After about 15 minutes, I'm here: I'd give out the model but its a confidential. Is this normal for complex models? If not, anyway to check for errors or check the file? It seems to load just fine into Cura, our CAD software and Meshlab. Meshlab says it has 4mill faces so size could be the problem.
  8. My wife and I graduated HS in Tampa many years ago so we know the hassle 😞. I'm just glad you all didn't float away. The Luckybot would make a terrible oar.
  9. I've been using hot tap water and my wife's cooking thermometer to pre warm the chocolate. Water at 33 C works well. BTW, I've updated all the profiles and released Beta 0.4 in Github. It tweaks the gcode to what you mentioned above as well as setting the default layer size to 0.5. So, nothing that will really help you but maybe it will give the next person a head start. https://hackaday.io/project/187144-food-printing-with-luckybot
  10. Well, 1. is a user error... like thinking ABS stored in humid environment should still print just fine years later. Definitely time to learn about tempering 😂 2. Yes. Someone needs to come up with some proper maintenance tools. I have figured out there is some cooking paper that after you cut the end off to fit on the build plate, leaves enough to lay under nozzle when it is just sitting there. 3. Seriously. Biggest issue. 5. Have you mastered the stopper removal yet? I spent 5 minutes the first time 😂 6. It can also create some awesome sculptures! Tiny little stalagmites under the nozzle form between prints. Some other plusses: 1. You have good chance of convincing your spouse it is a cooking device and letting you keep your 3D printer in the kitchen (although I think my wife is on to me) 2. Sustainability - Working with renewable resources. Even the scrap is reusable! 3. Particles in the air are not a big problem, unless you have a lot of kids and they smell the chocolate.
  11. @GregValiant Any problems? Honestly, you may be the first tester for my profiles. If you tweak anything, let me know what works 🙂 I'm also keeping a table of my material 🍫. https://docs.google.com/spreadsheets/d/1nOycKwzfE2wTM-pcfwQJhniCNGCOwwhmAR6NsiA-WdE/edit#gid=0
  12. Now I'm going to have to change all my passwords. % ssh um3 password: ultimaker password incorrect
  13. Creating a tuned Cura profile is harder than it seems!
  14. Hi all. For a fun side project, I got a LuckyBot Food extruder for my Creality Ender 3 Pro. It required an old version of Cura, "some pre-Gcode" to run, and a lot of tuning. Yuck!!!🤢 So I created a small Hackaday.io project to create some proper Cura printer, extruder, and material profiles. This is my first machine configuration for Cura so recommendations or suggestions on what I should change are welcome. If you have a LuckyBot, some testing would be appreciated too. https://hackaday.io/project/187144-food-printing-with-luckybot The actual config files are on github: https://github.com/burhop/cura-luckybot
  15. Just to wrap this up, I was able to update the olimex board (apt-get update), and then install cura-engine. So far, it doesn't seem like I've broken anything for my Ultimaker3 and everything seems to be working (albeit I'm running low on memory). Thanks for your help 🙂
  16. Should anyone still be reading this thread, I verified apt-get update no longer has space issues with the larger space for root. In my case, after this, I was able to sudo apt-get install python3-pip root@ultimakersystem-ccbdd3004767:~# apt-get update Get:1 http://security.debian.org jessie/updates InRelease [44.9 kB] Get:2 http://security.debian.org buster/updates InRelease [34.8 kB] Ign http://deb.debian.org jessie InRelease Get:3 http://deb.debian.org buster InRelease [122 kB] Get:4 http://deb.debian.org jessie Release.gpg [1652 B] Ign http://security.debian.org buster/updates InRelease Get:5 http://security.debian.org jessie/updates/main armhf Packages [759 kB] Ign http://deb.debian.org buster InRelease Get:6 http://deb.debian.org jessie Release [77.3 kB] Get:7 http://deb.debian.org buster/main Translation-en [5969 kB] Get:8 http://security.debian.org jessie/updates/main Translation-en [401 kB] Get:9 http://security.debian.org buster/updates/main armhf Packages [342 kB] Get:10 http://security.debian.org buster/updates/main Translation-en [187 kB] Get:11 http://deb.debian.org jessie/main armhf Packages [6675 kB] Get:12 https://dl.cloudsmith.io jessie InRelease [4864 B] Get:13 http://deb.debian.org jessie/main Translation-en [4581 kB] Get:14 http://deb.debian.org buster/main armhf Packages [7702 kB] Get:15 https://dl.cloudsmith.io jessie InRelease [4878 B] Get:16 https://dl.cloudsmith.io buster InRelease [5005 B] Get:17 https://dl.cloudsmith.io jessie InRelease [351 B] Ign https://dl.cloudsmith.io jessie InRelease Get:18 https://dl.cloudsmith.io buster InRelease [4999 B] Get:19 https://dl.cloudsmith.io jessie InRelease [4999 B] Get:20 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:21 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:22 https://dl.cloudsmith.io buster/main armhf Packages [174 kB] Get:23 https://dl.cloudsmith.io buster/main Translation-en [324 B] Get:24 https://dl.cloudsmith.io jessie Release.gpg [488 B] Get:25 https://dl.cloudsmith.io buster/main armhf Packages [74.0 kB] Get:26 https://dl.cloudsmith.io buster/main Translation-en [324 B] Get:27 https://dl.cloudsmith.io jessie/main armhf Packages [51.4 kB] Get:28 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:29 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:30 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:31 https://dl.cloudsmith.io buster/main Translation-en [324 B] Get:32 https://dl.cloudsmith.io jessie Release [4465 B] Get:33 https://dl.cloudsmith.io buster/main Translation-en [324 B] Get:34 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:35 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:36 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:37 https://dl.cloudsmith.io buster/main Translation-en [324 B] Get:38 https://dl.cloudsmith.io jessie/main armhf Packages [169 kB] Get:39 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:40 https://dl.cloudsmith.io buster/main Translation-en [324 B] Get:41 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:42 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:43 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:44 https://dl.cloudsmith.io buster/main Translation-en [324 B] Get:45 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:46 https://dl.cloudsmith.io buster/main Translation-en [324 B] Get:47 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:48 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Ign https://dl.cloudsmith.io jessie/main Translation-en Get:49 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Ign https://dl.cloudsmith.io jessie/main Translation-en Get:50 https://dl.cloudsmith.io buster/main Translation-en [324 B] Ign https://dl.cloudsmith.io buster/main Translation-en Get:51 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:52 https://dl.cloudsmith.io buster/main Translation-en [324 B] Ign https://dl.cloudsmith.io buster/main Translation-en Get:53 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Ign https://dl.cloudsmith.io jessie/main Translation-en Get:54 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Get:55 https://dl.cloudsmith.io jessie/main Translation-en [324 B] Ign https://dl.cloudsmith.io jessie/main Translation-en Fetched 27.4 MB in 1min 43s (265 kB/s) Reading package lists...

  17. Congrats @MariMakes. I'll 3D print some chocolate in your honor!
  18. Logging into the machine, all these guids are directories in /var/spool and contain about 12 old jobs over the past year.
  19. I keep getting this error in my Event log for my Ultimaker 3. It doesn't cause any problems but it makes it hard to view the real events. Is there any way I can fix or suppress this?

  20. Yeah, I need it for the Lime2 https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-LIME2/open-source-hardware THis is the Cortex-A7 processor. Same as RPi? In my case, we are just doing some minor stuff so no need for full blown CPU slicing
  21. I've got a non-standard nozzle size. I can set it for the extruder on the printer and for the material, but the drop down in Cura only lets me pick the same set of values (0.2 to 1.0). How can I change it to something else (see the drop down below. None of these values match my current nozzle or material.
  22. For a research project, I'd like to port a C++ program that uses the CuraEngine library to the Lime2 Linus board on my UM3. Right now, I have some Python running there just fine but for the next step, I'm hoping to uses some C++ that includes CuraEngine. In theory, this should work as it is "just" Debian Linux 8 and I don't need the UI from the rest of Cura or high performance. I'd like to hear that it is possible (or not) before going down that rabbit hole. Thanks!
  23. What I thought was no buffering above was a mistake. I was expecting the printer to pause to heat the build plate not realizing the UM3 doesn't just take a dump of GCODEs from a file. Darn tricky, these Ultimaker engineers 😉 It looks like I have to figure out what to do about the header info:
