Arduino 2560 + Pronterface on Mac endstop issue

I put together a mendel prusa using ramps 1.4 and Marlin.Nemu motors and mechanical endstops

All up to date software as for pronterface and Auduino 0023

First, all motors are working in both directions when testing so not problems there.

With pronterface I can move all motors with + but none when choosing any - number 1, 10 or 100.

I have been playing with Marlin configuration.h and sometimes can get the all x , y and z moving one direction or the other but not both with + or -

when clicking - Y I receive a message: echo:endstops hit: Y:19.99 and same message type with Z and X all echo with a - click.

With M119 I get:

SENDING:M119
x_min:H x_max:L y_min:H y_max:L z_min:H z_max:L

and with M114 I get:

SENDING:M114
X:0.00Y:0.00Z:0.00E:0.00 Count X:0.00Y:0.00Z:0.00

I think I need help in homing but not sure as this is my first printer.

Any help in setting this is greatly appreciated.

Thank you all..

The min endstops should be L when they are not triggered.

Try inverting your endstops in the firmware.

When setting the invert to true the motors move one way and when changed to false they move the other, but never move both at the same time.

very strange.

// The pullups are needed if you directly connect a mechanical endswitch between the signal and ground pins.
const bool X_ENDSTOPS_INVERTING = true; // set to true to invert the logic of the endstops.
const bool Y_ENDSTOPS_INVERTING = true; // set to true to invert the logic of the endstops.
const bool Z_ENDSTOPS_INVERTING = true; // set to true to invert the logic of the endstops.
//#define DISABLE_MAX_ENDSTOPS

where to you change this?

That is because the max endstops seem to be active and seem to be seen in the triggered state. If you don't have max endstops it looks like you need to un-comment #define DISABLE_MAX_ENDSTOPS.
