I wanted to add a thermocouple to my 3D printer's hot end. Ideally it would improve the quality of my printed objects as it would provide more accurate temperature readings with greater immunity from electronic noise generated by the stepper motors.


The PCB I have designed has the following features:

  • Fits onto the expansion headers already present on the Sanguinololu
  • Adds a MAX31855 temperature sensing chip
  • Enables temperature readings between -750degC and +1350degC +-2degC
  • Has a resolution of 0.25degC
