    Question Makerbase BLTouch Marlin Settings

    Hello.
    I bought Makerbase BL Touch. I've changed Marlin codes, but I don't get it.
    The nozzle hits the table. I want to lift nozzle at 0.2 mm, so it doesn't hit. It's set from the Marlin codes, but how?


    Which setting should I change?

    Code:
    #define X_PROBE_OFFSET_FROM_EXTRUDER -29 // X offset: -left  +right  [of the nozzle]
    #define Y_PROBE_OFFSET_FROM_EXTRUDER 0  // Y offset: -front +behind [the nozzle]
    #define Z_PROBE_OFFSET_FROM_EXTRUDER -0.8 // Z offset: -below +above  [the nozzle]
    
    
    // Certain types of probes need to stay away from edges
    #define MIN_PROBE_EDGE 10
    
    
    #define Z_CLEARANCE_DEPLOY_PROBE   15 // Z Clearance for Deploy/Stow
    #define Z_CLEARANCE_BETWEEN_PROBES  10 // Z Clearance between probe points
    #define Z_CLEARANCE_MULTI_PROBE     5 // Z Clearance between multiple probes
    //#define Z_AFTER_PROBING           5 // Z position after probing is done
    
    
    #define Z_PROBE_LOW_POINT          -10 // Farthest distance below the trigger-point to go before stopping
    
    
    // For M851 give a range for adjusting the Z probe offset
    #define Z_PROBE_OFFSET_RANGE_MIN -20
    #define Z_PROBE_OFFSET_RANGE_MAX 20

    How was the problem solved?
