    Issues with leveling: help with machine settings!

    Hi, I think my printing issues are due to leveling problems. The back left corner of my plate seems to be too low while the front right is too high. (yet the back right is perfect)
    I'm using the Monoprice mini delta printer
    Could someone please help me adjust my machine gcode settings to improve autoleveling? This is my current setting code:

    start

    G28; Calibration part start here
    M666 X0 Y0 Z0 ; Add your endstop values here after calibration
    M665 L120.80 R61.70 ; Sets default Delta Radius (change when calibrating)
    M301 P45.00 I0.07 D1000 ; Hot end settings
    M304 P100 I0 D0 ; Bed heater settings
    M500 ; Save settings

    G90 ; switch to absolute positioning
    G92 E0 ; reset extrusion distance
    G1 E20 F200 ; purge 20mm of filament to prime nozzle.
    G92 E0 ; reset extrusion distance
    G4 S5 ; Pause for 5 seconds to allow time for removing extruded filament
    G28 ; start from home position
    G1 E-6 F900 ; retract 6mm of filament before starting the bed leveling process
    G92 E0 ; reset extrusion distance
    G4 S5 ; pause for 5 seconds to allow time for removing extruded filament
    G29 P4 Z0.28 ; Auto-level ; ADJUST Z to set first layer height. Start with 0.02 adjustments.
    G1 Z30 ; raise Z 30mm to prepare for priming the nozzle
    G1 E5 F200 ; extrude 5mm of filament to help prime the nozzle just prior to the start of the print
    G92 E0 ; reset extrusion distance
    G4 S5 ; pause for 5 seconds to allow time for cleaning the nozzle and build plate if needed



    end
    G28
    M107
    M104 S0 ; turn off hotend heater
    M140 S0 ; turn off bed heater
    G91 ; Switch to use Relative Coordinates
    G1 E-2 F300 ; retract the filament a bit before lifting the nozzle to release some of the pressure
    G1 Z5 E-5 F4800 ; move nozzle up a bit and retract filament even more
    G28 X0 ; return to home positions so the nozzle is out of the way
    M84 ; turn off stepper motors
    G90 ; switch to absolute positioning
    M82 ;absolute extrusion mode
    G28
