PID tuning (Hotend)
PID (Proportional Integral Derivate) are three values that Prusa printers utilize to maintain a stable temperature on the hotend. You can use the PID tuning to calibrate these numbers in case you are experiencing small fluctuations in temperature readings of your printer's nozzle (e.g +/- 5 C°).
How to perform PID tuning
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.
Follow these steps:
- Once you open the PID calibration menu, set the temperature at which the calibration should run.
- To achieve optimal results, select a temperature you most commonly prefer for your prints (e.g. the temperature for PLA, PETG or other favorite material). However, the PID tuning will increase the general stability for all temperatures.
- The nozzle will heat up to the selected temperature in 5 cycles. During these cycles, the printer will determine the amount of power needed to reach the user-defined temperature and maintain it.
