Anet A8 Servo Z-Endstop Remix

thingiverse

The probe is mounted between the radiator and the extruder fan. I made this modification because the original one wouldn't allow me to use any other fan duct, only the original Anet A8. The microswitch, ground, and 5V supply are taken from the Z_MIN connector. The control signal of the servo is taken from SERVO0_PIN 27, which can also be found on the LCD pin 3 connector. My firmware settings (Marlin 1.1.x) include: #define Z_MIN_ENDSTOP_INVERTING true #define Z_ENDSTOP_SERVO_NR 0 #define Z_SERVO_ANGLES {127,5} #define X_PROBE_OFFSET_FROM_EXTRUDER -40 #define Y_PROBE_OFFSET_FROM_EXTRUDER -30 #define Z_PROBE_OFFSET_FROM_EXTRUDER 0 #define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 3) #define MULTIPLE_PROBING 2 #define AUTO_BED_LEVELING_LINEAR #define LEFT_PROBE_BED_POSITION 15 #define RIGHT_PROBE_BED_POSITION 180 #define FRONT_PROBE_BED_POSITION 15 #define BACK_PROBE_BED_POSITION 180 #define Z_SAFE_HOMING #define NUM_SERVOS 1 The Z offset is set using M851 (Don't forget to save M500).
