NOTE: This only applies to the EZABL Mini, not the EZABL Pro Mini as they use different sensors.
The adjustment in the EZABL Mini has a metal stop tab that prevents from overshooting the adjustment. If you are not careful and/or you use a screwdriver too larger (or too small) you can strip out the adjustment.
Use a #2-#2.5 size screwdriver to adjust this adjustment and GO SLOW. The adjustment on the mini is more sensitive than the full size if you are used to adjusting that sensor.
INCORRECT ADJUSTMENT POSITION. READ THE NOTES ON IMAGE. CORRECT ADJUSTMENT POSITION. READ THE NOTES ON IMAGE.
DAMAGED ADJUSTMENT DUE TO NOT CHECKING SCREWDRIVER SIZE/POSITION
