  1. I have an Ultimaker 2+. I've updated the firmware in the past, but recently I couldn't get it to work. I was eventually able to fix it, and thought I should post the solution here for others who run into the same roadblock. My computer is running Ubuntu 16.04, and I'm using Cura 2.5.0. I go to Settings > Printer > Manage Printers..., and click "Upgrade Firmware" and finally "Automatically upgrade Firmware". It says "Starting firmware update, this may take a while", and then about a second later fails with "Firmware update failed due to a communication error". First, this is a terribl
  2. The best retraction settings to use seems to be mostly determined by material, so I agree that materials.txt would be a great place for them. Needing to set them in Cura means that I effectively have to keep separate notes about what settings work best with each material, and then remember to make those adjustments in Cura each time. Seems dumb when this could be entirely automated.
  3. Thanks. That guide looks extremely useful. My fans were already set to 100%, so I tried reducing the temperature by 10C down to 200C (the default PLA temp seems to be 210C). I aborted this right away, as the print was not sticking to the bed at all. (Aside: how does one clean PLA off the outside of the nozzle? Or should I just not bother?) I bumped it up to 205C, and this adhered well, and reduced, but did not eliminate, the pillowing. Should I just not expect the included gcode file to print without flaws?
  4. I just tried printing the Voronoi heart model that was on the SD card included with my Ultimaker2. It seems to be this design, but I'm getting some noticeable flaws on the top surface of the inner heart. Instead of being flat, it has a bunch of holes and dimples. How can I fix this problem? I assume it's caused by the still-molten plastic sagging. I've heard adding shells can help with this, but I assumed the files on the included SD should print fine without modification on a properly calibrated UM2. This was printed with the default settings with the included filament (Ultimaker 2.85
