CoreXY - Z-Achse - homing
26. May 2016 01:50
Moin,

ich habe nun auch meinen ersten CoreXY (nach Thingiverse: Core XY Printer) aufgebaut.
Alle Achsen bewegen sich korrekt, homing der X- und Y-Achse funktioniert korrekt.
Der Z-"Endstop" (FSR-ABL) löst zuverlässig aus - Kontrolle mittels M119.
Wenn ich nun das Homing der Z-Achse ausführe, dann stoppt die Bewegung der Z-Achse nicht, wenn der Z-Endstop auslöst.

Ich bitte um Tipp's, welche Konfig-Einstellungen ich überprüfen soll. (Marlin 1.1-RC6)

Danke schon mal.

Gruß

Hier der entsprechende Teil meiner aktuellen Konfig.

// 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

#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN

// To use a probe you must enable one of the two options above!

// This option disables the use of the Z_MIN_PROBE_PIN
// To enable the Z probe pin but disable its use, uncomment the line below. This only affects a

So, ich habe die Ursache gefunden:

Ich hatte
// A Mechanical Probe is any probe that either doesn't deploy or needs manual deployment
// For example any setup that uses the nozzle itself as a probe.
#define MECHANICAL_PROBE
genommen, aber wohl den Hinweistext falsch verstanden (FSR-Board als Z-Min).

Es muss
#define FIX_MOUNTED_PROBE
sein.
