Limit Switch Problems (see desciption)

Hi all.
I am building a Sculptr Delta MK1 and have been having problems running Marlin 2.0 on a Ramps 1.4. When homing, the limit switches are not being triggered (even though they are), and causes a loud grinding noise.
I tried to troubleshoot this by using the M119, endstop status gcode, and despite what I do, I cannot trigger those things. I have tried multiple wiring combinations to no avail.
Pweeze helwp...

How about some details? like your configuration files settings and what type of endstops?

I'm using normal mechanical endstops and I have attached the firmware I'm using - it's a branch of marlin...
Thanks for your help.

normal? as in 3 wire or 2 wire

Zip file is empty

Hi sorry. This should work. [drive.google.com]

The limit switch is a mechanical one, it hase 3 pins of which two I am using.

If you only using two pins, it should be gnd and signal. and then you enable the pullup

eg these
MK4duo/Configuration_Core.h:#define ENDSTOPPULLUP_XMIN false
MK4duo/Configuration_Core.h:#define ENDSTOPPULLUP_YMIN false
MK4duo/Configuration_Core.h:#define ENDSTOPPULLUP_ZMIN false
MK4duo/Configuration_Core.h:#define ENDSTOPPULLUP_XMAX false
MK4duo/Configuration_Core.h:#define ENDSTOPPULLUP_YMAX false
MK4duo/Configuration_Core.h:#define ENDSTOPPULLUP_ZMAX false
MK4duo/Configuration_Core.h:#define ENDSTOPPULLUP_Z2MIN false
MK4duo/Configuration_Core.h:#define ENDSTOPPULLUP_Z3MIN false
MK4duo/Configuration_Core.h:#define ENDSTOPPULLUP_Z2MAX false
MK4duo/Configuration_Core.h:#define ENDSTOPPULLUP_Z3MAX false
MK4duo/Configuration_Core.h:#define ENDSTOPPULLUP_ZPROBE false

How would it be defined in the Configuration_Delta.h file?

Never mind figured it out.
Thanks so much for your help.
