Marlin 2.0 Auto Leveling Problem

[Roberts_Clif]

When I started Out used these lines of code to adjust my Proximity Sensor to work.
These are a modified Code from Marlin 1.1.9BF to work with Marlin 2.
Adjusted them with your offset for you to try.


// The size of the print bed
#define X_BED_SIZE 200
#define Y_BED_SIZE 195

// Travel limits (mm) after homing, corresponding to endstop positions.
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define X_MAX_POS 210
#define Y_MAX_POS 195
#define Z_MAX_POS 210 // do not know your max Z Height you may want to adjust.

#define GRID_MAX_POINTS_X 6
#define GRID_MAX_POINTS_Y GRID_MAX_POINTS_X

// Set the boundaries for probing (where the probe can reach).
// setup for "Enter Your Sensor Here"
#define LEFT_PROBE_BED_POSITION MIN_PROBE_EDGE + 10
#define RIGHT_PROBE_BED_POSITION (X_BED_SIZE - (MIN_PROBE_EDGE + 10))
#define FRONT_PROBE_BED_POSITION MIN_PROBE_EDGE + 15 // 8 For Your Sensor
#define BACK_PROBE_BED_POSITION (Y_BED_SIZE - (MIN_PROBE_EDGE)) // + 10 For Your Sensor
