  1. Here's a blogpost with a summary of the repair: https://www.coredump.ch/2020/08/25/ultimaker-2-repair/
  2. I can confirm that in our case replacing U6 and D16 helped! The UM2+ is again printing happily, for the cost of about 2$ of spare parts 🙂 Already has almost 5000 printing hours. In order to replace the parts, you'll probably need a hot-air rework station, solder paste, flux and maybe a desoldering station (vacuum pump) for cleaning the pads after desoldering. I ended up both desoldering and desoldering the IC with the hot-air rework station.
  3. @Alexjwb123 did you also replace the diode D16, or only U6?
  4. Here's another thread with the same issue (U6 burned out):
  5. Diode D16 was also broken, as @Torgeir suggested. Will replace U6 and D16, let's hope this will work. I found a few "classic bugs" on the PCB... Could they sufficiently conduct to kill the regulator? I assume a component failure is more likely...
  6. Same problem here... UM2+ is about 6 years old. @Riboflavin did you solve your issue? The chip would be easy to replace, but if it's just a symptom and not the cause, we should find the cause first...
  7. Are there signatures available for the AppImage download of Cura? After all, we're simply downloading and executing a binary on our computers...
  8. For the people coming here from Google: https://ultimaker.com/en/resources/20982-custom-materials-ultimaker2-plus
  9. I upgraded my UM2 to an UM2+ yesterday and upgraded the firmware using the current beta. Now it appears that when changing materials, the heat bed is also heated. That extends the time it takes to change filament by several minutes. Is that really the case? If yes, why? Also, the progressbar does not seem to work properly in the "change material" dialog.
  10. Small addendum: We noticed that the fork handle also fits the big spoons in the same IKEA cuttlery set That wasn't on purpose at all, I barely managed to finish printing all the prototypes
  11. (Here's my entry, just in time!) My wife occasionally has problems with her joints. When they hurt and are swollen, she can barely hold a fork in her hand. There are "orthopedic" forks with thicker handles that can be bought, but they're usually expensive and/or ugly. We wanted something that would benefit everyone by making a 3D-printable handle for widely used (and easily available) IKEA forks. Goals: modify / improve a fork so that it can be used by people with joint problems it needs an "angled" surface, so that it's easier to grip it should fit a regular IKEA Dragon fork it shou

  13. Hi all This might interest some of you. As my student research project thesis in 2013 I created a Python library for 3D design / visualization. To quote the description from my project page: Example of a 3D visualization: So to summarize, this library lets you easily convert data (like time series, for example) to 3D visualizations in the OpenSCAD format, that can in turn be converted to STL. Project is here: https://github.com/dbrgn/tangible Docs: http://tangible.readthedocs.org/ Thesis: http://eprints.hsr.ch/351/ Would be great to get some feedback! Danilo
  14. Oops, sorry. It's an Ultimaker 1 of course. The wooden one. I somehow mixed it up Thanks for the help.
