  1. Hello everybody. I have problems with my Ultimaker Original. It started 3 months ago. Temperature readings were inaccurate as it was too cold or too hot. PLA strated making bubbles. Ok, I though I need new temp sensor. Oredered 2 of them to prevent off times in future. So I replaced temperature sensor and started test print. Heated up to 220/220°C, but as soon as it started homing, the temperature drop to 190°C and printer continued with heating to 220°C. It reached 220°C again, but real temperature was in that moment about 250°C. I thought it was a bad temperature amplifier. So I changed th

I installed Cura 14.01 and it asked me to update firmware, so I did it.
  4. Hello guys. Today I finished my Ultimaker Original build. What a machine. I was impressed by the quality of the components during the build. After about hour of messing with bed leveling I made my first print. It was the Ultimaker robot which was loaded in Cura 14.01. I choose the quick settings in the simple version of settings and clicked print. The final product wasnt bad, but it is only 1/2 of the original height.(I got about 1,7cm instead of 3,3cm) I printed with PLA/PHA from ColorFABB on 203°C, blue tape, Cura 14.01 via USB. I also have Ulticontroller connected, but didn't used it. The
