controller collapses while hrating

Recommended Posts

Hello,

I have serious trouble with a new ultimaker:

The Ultimaker was bought two or three month ago but only used six short times for test printings of adjustable z-axis-mounting and -axis-caps. That worked quite fine.

Today I wanted to do the first bigger printing job for a mold part. After about 1 3/4 hour printing this happend:

- temperature went down to 162 and than 156 degrees

- printhead continud to move the shape but no more material flow

- smoke blowing out at the print head

I stoped printing process and turned ultimaker off. Now, when restarting the printer this happens:

- turns on normal, controller appears normal

- controller shows 48/0 degreees a moment, than 18/0

- After selecting a print file controller shows "heating" on the bottom line

- in the first line controller jumps from 18/0 to 19/0 and remains

- After about 1/2 to 1 minute the controller collapses and reacts no more, while showing psychodallic orange glow behind the letters and no reaction any more.

Thank you for any solution or idea ...

Arne

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
