====== Anycubic Mega S - Klipper Einrichtung und Konfiguration ======

===== Klipper Config Check =====

==== Calibrate PID settings ====

Um die Temperatur des Extruder zu kalibrieren führt man den ersten Befehl aus, wartet ab bis der Kalibriervorgang abgeschlossen wurde und speichert die gefundenen Werte in der printer.cnf ab (passiert automatisch und wird am Ende eingefügt).

<code python>
PID_CALIBRATE HEATER=extruder TARGET=170

Um die Temperatur des Printbed zu kalibrieren führt man den ersten Befehl aus, wartet ab bis der Kalibriervorgang abgeschlossen wurde und speichert die gefundenen Werte in der printer.cnf ab (passiert automatisch und wird am Ende eingefügt).

Basiskonfiguration (Beispiel) für einen Anycubic Mega S ohne Modifikationen / Originalzustand

# This file contains pin mappings for the Anycubic i3 Mega with
# Ultrabase from 2017. (This config may work on an Anycubic i3 Mega v1
# prior to the Ultrabase if you comment out the definition of the
# endstop_pin in the stepper_z1 section.) To use this config, the
# firmware should be compiled for the AVR atmega2560.

# See docs/Config_Reference.md for a description of parameters.
