Duet 3d wifi homing problems
-
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.
