PID Tuning your 3D Printer with Marlin Autotune

G-code file is making 3 cycles autotune PID for hotend. The new values will be saved to EEPROM automatically. You do not need G-code terminal. Just save program to SD card and press start. Parameters like number of cycles (8), temperatures (200C, 60C), and fan speed (100%) you can simply modify by opening gcode file in text editor. Requres: #define PIDTEMP or #define PIDBEDTEMP, #define EEPROM_SETTINGS
