Description

Intended to be used with the BLTouch bed leveling sensor
https://www.indiegogo.com/projects/bltouch-auto-leveling-sensor-for-3d-printers/x/9627612#/story


Print and update Marlin

If you use any other firmware I cannot help.
Edit the Configuration.h file with the following changes;

Under Mechanical Settings

Ensure

const bool Z_MIN_ENDSTOP_INVERTING = false;
const bool Z_MIN_PROBE_ENDSTOP_INVERTING = false;


Under Bed Auto Leveling

Uncomment

 #define AUTO_BED_LEVELING_FEATURE

Change

  #define X_PROBE_OFFSET_FROM_EXTRUDER 40     // Z probe to nozzle X offset: -left  +right

  #define Y_PROBE_OFFSET_FROM_EXTRUDER 0    // Z probe to nozzle Y offset: -front +behind

  #define Z_PROBE_OFFSET_FROM_EXTRUDER -4.35  // Z probe to nozzle Z offset: -below (always!), depends on the position of the set screw.



Under R/C SERVO support

Uncomment

#define NUM_SERVOS 3

#define Z_ENDSTOP_SERVO_NR 0


Uncomment and change the values in the last braces as follows.

#define SERVO_ENDSTOP_ANGLES {{0,0}, {0,0}, {10,90}}


That's it!

You must do a G28, which homes X and Y axes
Before issuing a G29, which executes the bed level probing
