Grounding the print head for better temperature stability

Recommended Posts

I had temperature instability problems since I got my Ultimaker like mentioned at the link below.


The temperature monitor was showing ~20C more or less than the actual.

The solution I found is grounding the print head by connecting the gnd wire of the fan to one of the long screws. I don't know why but it shows the correct temperature immediately after grounding. The place I live has a dry climate. Maybe it has something to do with static electricity. Here is a possibly related phenomena:


I hope this helps someone.

Great information, thanks! Some people have found if they seperate the temperature probe wires *farther* from the fan wiring then their temperature is more stable. So just moving the wires a little bit might be enough.

edit: I'm talking about the probe wires *below* the circuit board on the head. Once the signal goes through the amplifier it is not so sensitive to crosstalk.

    • "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.
