Z - Probe on Z-Min Endstop

Post by Johncoffee »

I'm trying to setup my z-Probe (mini height IR sensor board) on my Rambo v1.3 board.

I've connected it to the Z-min endstop and modified my configuration.h file to this:
(according https://www.repetier.com/documentation/ ... z-probing/)

#define FEATURE_Z_PROBE true
#define Z_PROBE_PIN 23 // this is the Zmin endstop connector
#define Z_PROBE_PULLUP true
#define Z_PROBE_ON_HIGH false
#define Z_PROBE_X_OFFSET 0
#define Z_PROBE_Y_OFFSET 0
// Waits for a signal to start. Valid signals are probe hit and ok button.
// This is needful if you have the probe trigger by hand.
#define Z_PROBE_WAIT_BEFORE_TEST false
/** Speed of z-axis in mm/s when probing */
#define Z_PROBE_SPEED 2
#define Z_PROBE_XY_SPEED 150
/** The height is the difference between activated probe position and nozzle height. */
#define Z_PROBE_HEIGHT 39.91
/** These scripts are run before resp. after the z-probe is done. Add here code to activate/deactivate probe if needed. */
#define Z_PROBE_START_SCRIPT ""
#define Z_PROBE_FINISHED_SCRIPT ""



when testing it using a M119 command, all is fine and the Z probe is being recognized H & L:
READ: x_max:L y_max:L z_min:L z_max:L (when probe is OFF)
and
READ: x_max:L y_max:L z_min:H z_max:L (when probe is ON)

But when testing via the G31 command, I always get the same result when the probe is high or low:
READ: Z-probe state:H (when the probe is OFF)
and
READ: Z-probe state:H (when the probe is ON)

Can anybody give me a hint what could be wrong?

I use the Z-min pin 23 instead pin 63 as repetie recommends as I have problems to figure out where that pin is on my Rambo board.


Thanks for any help.

Found the problem: Z_min Endstop is on pin 10 on the Rambo board and not 23 ... :D
