I use only 5V to power capacitive probe LJC18A3-HZ/BX and it's working fine. For Marlin 1.1.9: Use Marlin-1.1.9.ABL.with-probe-LJC18A3-H-Z-BX.zip to upgrade Anet A8 stock with capacitive probe LJC18A3-H-Z/BX https://www.thingiverse.com/download:5413416 https://youtu.be/vKbX2yUdtsQ Tutorial for Z-Offset: https://www.youtube.com/watch?v=Q5M7DvdMcew For Marlin 1.1.8: https://github.com/MarlinFirmware/Marlin/archive/1.1.8.zip Marlin 1.1.8 modification Configuration.h 127: #define CUSTOM_MACHINE_NAME "Anet A8 autolevel" 488: //#define ENDSTOPPULLUPS 495: #define ENDSTOPPULLUP_XMIN 496: #define ENDSTOPPULLUP_YMIN 504: #define Z_MIN_ENDSTOP_INVERTING true 508: #define Z_MIN_PROBE_ENDSTOP_INVERTING true 636: #define FIX_MOUNTED_PROBE 693: #define X_PROBE_OFFSET_FROM_EXTRUDER +62 694: #define Y_PROBE_OFFSET_FROM_EXTRUDER 5 695: #define Z_PROBE_OFFSET_FROM_EXTRUDER 0 698: #define XY_PROBE_SPEED 6000 709: #define MULTIPLE_PROBING 3 778: #define Z_HOMING_HEIGHT 4 794: #define X_MIN_POS -33 795: #define Y_MIN_POS -5 796: #define Z_MIN_POS 0 797: #define X_MAX_POS X_BED_SIZE 798: #define Y_MAX_POS Y_BED_SIZE 799: #define Z_MAX_POS 240 880: #define AUTO_BED_LEVELING_BILINEAR 920: #define GRID_MAX_POINTS_X 3 921: #define GRID_MAX_POINTS_Y GRID_MAX_POINTS_X 924: #define LEFT_PROBE_BED_POSITION 35 925: #define RIGHT_PROBE_BED_POSITION 195 926: #define FRONT_PROBE_BED_POSITION 25 927: #define BACK_PROBE_BED_POSITION 195 930: #define MIN_PROBE_EDGE 10 1041: #define Z_SAFE_HOMING 1049: #define HOMING_FEEDRATE_XY 3600 1050: #define HOMING_FEEDRATE_Z 240 1293: #define LCD_LANGUAGE en 1402: #define INDIVIDUAL_AXIS_HOMING_MENU Z-Offset with Pronterface: http://www.pronterface.com/ with Hotbed 60°C M851 Z0; Z offset=0 M500; Save in EEPROM M501; Read EEPROM M211 S0; negative value permitted G28; Home All G1 X110 Y110 Z0; Move to center ; move Z axis to touch bed and read Z value M851 Z[value]; value with negative - M211 S1; Disable negative value M500; Save in EEPROM M501; Check last line with Z value offset Start G-Code: ;Basic settings: Layer height: {layer_height} Walls: {wall_thickness} Fill: {fill_density} ;Print time: {print_time} ;Filament used: {filament_amount}m {filament_weight}g ;Filament cost: {filament_cost} ;M190 S{print_bed_temperature}; Uncomment to add your own bed temperature line ;M109 S{print_temperature}; Uncomment to add your own temperature line G21; metric values G90; absolute positioning M107; start with the fan off G28; home all G29; autolevel G1 Z15.0 F6000; move platform down 15mm G92 E0; zero extruded length G1 F200 E3; extrude 3mm of feed stock G92 E0; zero extruded length again G1 F6000 ;Put printing message on LCD screen M117 Printing...
