PID tuning is a calibration procedure that ensures the printer holds a stable target temperature at all times. PID (Proportional Integral Derivate) is used on the Original Prusa printers to maintain a stable temperature on the hotend. You can use the PID tuning to calibrate its values in case you are experiencing small fluctuations in temperature readings of your printer's nozzle (e.g +/- 5 °C).
Starting with firmware version 2.0.12., PID tuning is an optional calibration procedure, which is super easy to perform. It can be found in the LCD Menu -> Calibration -> PID calibration.
