Flsun Delta Kossel W/ Marlin 1.1.6f-AC FW not leveling properly

Hi everyone, this is my first post here (and I also posted the same thing in the Marlin FW section)
I'm helping a friend fix his Flsun Kossel Delta. We never could get it to work properly, and the fact that it shipped with the wrong firmware probably doesn't help the vendor's (Flsun) case. I reflashed it and it it has the proper firmware, but it doesn't home properly (i have to home it twice) and it starts to print about 50mm higher than the bed. im really confused as to why this is doing this, and i have looked up how to fix this issue with no luck getting it to work. i have edited my Configuration.h file multiple time and it still doesn't work the way it should.

Any help would be much appreciated, and i've included the Configuration flies for the Firmware. I'm just stumped as to why this printer wont work properly

Printer: Flsun Kossel Delta Linear Guide Version with Large Heated Print Bed (Size 240*285mm)
Software: Repetier-Host And Repetier-Server using USB as Connection method

If the printer has a Z-probe you can run G30 ( single z-probe ) after G28 ( homing ). That will hopefully tell the printer where z=0 really is.

Homing a Delta more than once is not untypical. Sometimes it is better to manually move the effector to the center and then send G28. Or add such lines in the end code of the slicer.

...
;end code of the slicer
G91    ;set relative moves
G1 Z10 F2000    ;move the effector 10mm above the part
G90    ; set absolute moves
G1 X0 Y0 F2000    ;move the effector to the center of the bed
M84    ; switch off motors
...

Hi,
Ive used the G30 command before. But my endstops blink between 0 and ? on the lcd screen. Even after the printer finds the endstops. Also, this model doesnt have a probe, but a NC switch on the extruder itself.
Im beginning to think i still have the wrong firmware installed
