Z_HOME_DIR 1

hi all

i just uploaded Repetier-Firmware to a printrboard.
i'm building an ord-style bot. the z-endstop is on top of the axis.
so i configured Z_HOME_DIR 1. but then z-home doesn't work. as soon as i switsch to Z_HOME_DIR -1 it works but then it moves to the wrong direction.
software endstops are set to false.
any idea what i'm doing wrong?
any help is very much appreciated.

cheers
simon

There are two pin definitions in pins.h

#define Z_MIN_PIN          36
#define Z_MAX_PIN          -1

Some boards like printrboard have only connections for one endstop. In this case you need the switch the pin number from MIN_PIN to MAX_PIN. If you have a RAMPS with 6 Endstops, you need to put it in the max endsop slot. The best place to replace the PIN definition is in Configuration.h after pins.h is included! In your case put

#define Z_MIN_PIN          -1
#define Z_MAX_PIN         36

after

#include "pins.h"
