This is a list of procedures to perform in order to calibrate a FDM/FFF 3D printer.

Heaters PID constants

Perform this calibration to ensure the control algorithms for heating elements do the right job and do not overshoot/undershoot/oscillate.

This only needs to be done once per maintenance period.

1. Use the M303 E0 S to calibrate the hot end and save the reported values with M301 P I D.
2. Use the M303 E-1 S to calibrate the bed and save the reported values with M304 P I D.

The list below is compiled to inform, guide, and inspire budding security researchers. Oh and to pick something for bedtime reading too.

Included in the list are works on the following topics related to MCU/SoC security:

• Secure boot
• Fault injection
• Side channel attacks

At the end of the list, there is also a section with links to articles of potential general interest, not addressing vulnerabilities in any specific device.
