Configuration.h

#define NOZZLE_TO_PROBE_OFFSET { -44, -6, 0 } // install normal side
#define DEFAULT_AXIS_STEPS_PER_UNIT   { 80, 80, 400, 102.8 } // my E-Step is 102.8
#define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 4) // I use 4, it's quite slow but more accurate
#define RESTORE_LEVELING_AFTER_G28 // Restore bed level after auto home

Post installation

1. Make sure you level 4 bed corners (by paper ~ 0.1 mm)
2. Do probe z offset by
   1. Run Autohome // it will stop at ~ Z 20
   2. Manual move z to 0 by 10 (twice)
   3. Move z again with by (0.0025) // Will see it might more or lower than 0
   4. Move it to bigger than 0 value with one step // Now you will see the nozzle is not touching bed yet
   5. Go to motion > bed leveling > probe z offset // Move it in negative value until it hit your paper firmly (~0.1 mm thickness)
   6. Remove paper and you must see the gap between nozzle and bed
   7. Move nozzle down a little bit and must not hit the bed (might add around 0.04 - 0.09, example: current mine -3.0 then I move down to -3.08)
   8. Store configuration
3. Do Bed leveling
4. Store configuration
