Hi, today I installed Cura 15.01-RC7 and uploaded the firmware to the Ultimaker 2 of my local hackerspace. Printing works fine, but changing the filament doesn't work properly. The stepper motor that feeds the material goes bonkers (in both steps: removing and inserting material). I switched back to the 14.09 version of the firmware and the behaviour disappeared immediately. Does anyone else have this problem? Edit: Today I tried the firmwares that are shipped with cura version 15.01-RC8 and 14.12.1 and recorded videos of insertion and removal of material. The situation described above did not change.
