Duet 3d wifi homing problems
-
Please post your homing files too.

Here are and the homing files for this setup.
Homing file for z axis:
; homez.g
; called to home the Z axis

; generated by RepRapFirmware Configuration Tool on Thu May 03 2018 12:42:37 GMT+0300 (EEST)
G91 ; relative positioning
G1 Z5 F6000 S2 ; lift Z relative to current position
G1 S1 Z-185 F1800 ; move Z down until the switch triggers
G92 Z0 ; set Z position to trigger height; Uncomment the following lines to lift Z after probing

G1 S1 Y-275 F1800 ; move quickly to Y axis endstop and stop there (first pass)

G1 S1 Z-185 F1800 S1 ; move Z down stopping at the endstop
G90 ; absolute positioning
G92 Z0 ; set new Z position
;G1 Z5 F100 S2 ; uncomment this line to lift the nozzle after homing -
In the following sentence:
but when i am about to home all of the axis while the leds of x and y axis goes off and the E0 axis goes on the steppers doesn't stop
when you say "when I am about to home", do you mean you have not actually tried to home the printer? The homing switches are only used during homing moves.
-
I have tried multiple times to home all of the axis both individually and simultaneously but despite the fact that all of them move in the right direction when they hit the end stop switches (or come close to the induction sensor for the z axis and the led on the board goes off for the x and y axis and on for z the motors doesn't stop which forces me to execute the emergency stop function.
-
Please test your X and Y endstops as described at https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Test_endstop_switches and test the Z probe as described at https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe.

I have tested and calibrated the x and y end stop switches and despite the fact that they work as decribed in the link when i excecute the homing function despite the fact that the switches are touched and there is a change in the board leds the stepper motors doesn’t stop so i can’t calibrate the induction sensor i have for the z axis
-
@argiros-apostolos, is it just Z homing that doesn't work? Or are X and Y homing failing too?
-
All of the x y and z axis fail to home
-
I suggest you start by trying individual homing moves. For example, if you send G91 followed by G1 S1 X-250 F600 then the head should move towards the X axis minimum at 10mm/sec, stopping when you trigger the endstop switch.
-
I have tried that and again it doesn't stop when the switch is triggered.
-
Also i have updated my duet wifi firmaware to version 1.21 and now when i just try to move an axis this message appears:
This appears for the x axis:
M120
G91
G1 X10 F6000
M121
Error: G0/G1: insufficient axes homed
Error: Pop(): stack underflow! -
To allow axis movement before homing, put M564 H0 in config.g.
-
I have changed some of my connections and now i can successfully home my x and y axis but not the z axis (again i have the problem of the motor not stopping despite the fact that the led on the induction sensor is light up) (and the induction probe for the z axis is connected to the E0 stp pin threw a schottky diode).

Test and calibrate the Z probe, see https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe.

See #1 in the FAQ at https://duet3d.dozuki.com/Wiki/FAQ.

Thank you very much now all axis home perfect.
