Hello everyone and thank you in advance for reading my post. For the last two days I have been trying to get the Z axis to function properly and am reaching my wits end. I am using marlin software,ramps 1.4 board with arduino mega 2560, and a inductive sensor as a endstop/probe for the Z axis. The probe is ignored when under manual control despite triggering properly, I check with M119 command. It is however acknowledged when the printer is homing it self. In addition to this the bed is lowered instead of raised when homing,which is probably because marlin kind of forces the probe to be a min endstop. In conclusion, I need help in getting the probed acknowledged by the printer when triggered and to get that probe treated as a max endstop instead of a min endstop. Thank you again for reading my post and please help me if you can.(My Marlin configuration file is below.)

// Enable Z_MIN_PROBE_ENDSTOP to use _both_ a Z Probe and a Z-min-endstop on the same machine.
// With this option the Z_MIN_PROBE_PIN will only be used for probing, never for homing.
//
// *** PLEASE READ ALL INSTRUCTIONS BELOW FOR SAFETY! ***
//
// To continue using the Z-min-endstop for homing, be sure to disable Z_SAFE_HOMING.
// Example: To park the head outside the bed area when homing with G28.
//
// To use a separate Z probe, your board must define a Z_MIN_PROBE_PIN.
//
// For a servo-based Z probe, you must set up servo support below, including
// NUM_SERVOS, Z_ENDSTOP_SERVO_NR and SERVO_ENDSTOP_ANGLES.
//
// - RAMPS 1.3/1.4 boards may be able to use the 5V, GND, and Aux4->D32 pin.
// - Use 5V for powered (usu. inductive) sensors.
// - Otherwise connect:
// - normally-closed switches to GND and D32.
// - normally-open switches to 5V and D32.
//
// Normally-closed switches are advised and are the default.
//
// The Z_MIN_PROBE_PIN sets the Arduino pin to use. (See your board's pins file.)
// Since the RAMPS Aux4->D32 pin maps directly to the Arduino D32 pin, D32 is the
// default pin for all RAMPS-based boards. Some other boards map differently.
// To set or change the pin for your board, edit the appropriate pins_XXXXX.h file.
//
// WARNING:
// Setting the wrong pin may have unexpected and potentially disastrous consequences.
// Use with caution and do your homework.
//
//#define Z_MIN_PROBE_ENDSTOP
// Enable Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN to use the Z_MIN_PIN for your Z_MIN_PROBE.
// The Z_MIN_PIN will then be used for both Z-homing and probing.
// Private Comment:Top command allows probe to act as min endstop while bottom command only acts as
//min endstop during homing. I need to get the probe to act as a max endstop however. I also need
//to avoid using the top command since it is supposed to use both a endstop and probe at the same time.
