Introduction
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.
Features
The PCB I have designed has the following features:
- Fits onto the expansion headers already present on the Sanguinololu
- Adds a MAX31855 thermocouple to digital convertor chip
- Enables temperature readings between -200°C to +1350°C ±2°C
- Has a resolution of 0.25°C
- Can sample at 10Hz
