Reversing X axis homing issues on Prusa I3 with Marlin
February 02, 2015 02:56PM
Hi. I'm trying to reverse my homing direction for X axis on my prusa i3 using Marlin. I edited the value in the firmware from X_HOME_DIR -1 to 1 and also moved the wires for the endstop from pins 6 to 5 on my RAMPS 1.4 but it doesn't work.

When I connect through repetier and try to do a X homing it doesn't move. Also If I move the X axis lets say by 10 mm it works but when I press the homing button the position resets to 0 without moving. I can see the mesage endstop hit: X on the display if it helps somehow.

This works perfectly if I use X_HOME_DIR -1 and plug the endstop in the 6th pins.

Any idea?
Regards.

You'll also need to make sure the following lines are commented out, as applicable:
//#define DISABLE_MAX_ENDSTOPS
//#define DISABLE_MIN_ENDSTOPS

That's it, thank you so much. I didn't relize about that value.
