autonivelacion de cama
#1
Hola a todos tengo una impresora 3d tipo delta mas precisamente una "Anycubic kossel linear", y esto queriendo configurarle la autocalibracion de la cama mediante el codigo g29
pero no encuentro demasiada info en internet y soy nuevito en esto.

por lo poco que logre recolectar de info arme el hard de esta manera https://www.youtube.com/watch?v=IN8aKoTFaqc

luego en el marli habilite el autolevel bed.  parte del codigo

#define ENABLE_AUTO_BED_LEVELING // Delete the comment to enable (remove // at the start of the line)

#ifdef ENABLE_AUTO_BED_LEVELING

  #define Z_RAISE_BETWEEN_PROBINGS 5  //How much the extruder will be raised when traveling from between next probing points


  //If defined, the Probe servo will be turned on only during movement and then turned off to avoid jerk
  //The value is the delay to turn the servo off after powered on - depends on the servo speed; 300ms is good value, but you can try lower it.
  // You MUST HAVE the SERVO_ENDSTOPS defined to use here a value higher than zero otherwise your code will not compile.

                          // - If stepper drivers timeout, it will need X and Y homing again before Z homing
                          // - Position the probe in a defined XY point before Z Homing when homing all axis (G28)

    // compensate by interpolating between the nearest four Z probe values for each point.

al poner g29 hace esto https://www.youtube.com/watch?v=q_EmaUWAGQs
alguien me ayuda o me orienta en que la estoy errando 
Gracias
