Duet 3d wifi homing problems
-
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.

Thank you very much now all axis home perfect.
