Recommended Posts

Hey guys.

Im new to the Ultimaker community and got my first 3D Printer. I just finish my assembly of the original + and from the beginning go a error. " Err: MAXTEMP BED." I read the forum and i tried the cable from the heated bed connection and same thing. Also on the Ultimaker Controller the BIG "H" is fluctuation the temperature.( from 300 too 500 degrees Any help will be appreciated. thanks

It's the temp sensor cable - not the heater cable. Disconnect this cable from the board underneath and measure the resistance. It should be a steady 108 ohms or so (depending on temperature). 300 degrees is over 200 ohms I think so if the resistance is fluctuating between 100 ohms and 200 ohms that is the problem. Try jiggling the wire where it meets the heated bed. it could be the wire isn't screwed into the bed properly.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
