Homing axis Delta Printer doesn't work

PhilippS

Hi there,

I built a Delta 3D Printer with the Duet3d 2 Ethernet and got problems homing the 3 axis.
After clicking "home all" all motors are turning two times for about half a second.

Following coordinates are displayed:
x 0, y 0, z 800
Now it is possible to move in z axis, but not in x or y axis.

The lights for the end stops are turning if I am pushing them manually, while homing the lights are off.

Following the gcode for "home all":

; homedelta.g
; called to home all towers on a delta printer

G91 ; relative positioning
G1 H1 X1455 Y1455 Z1455 F900 ; move all towers to the high end stopping at the endstops (first pass)
G1 H2 X-5 Y-5 Z-5 F900 ; go down a few mm
G1 H1 X10 Y10 Z10 F180 ; move all towers up once more (second pass)
G1 Z-5 F3000 ; move down a few mm so that the nozzle can be centred
G90 ; absolute positioning
G1 X0 Y0 F3000 ; move X+Y to the centre

What should be changed/done to fix this problem?

Thanks!

Can you please post your full config.g and the results of sending M122 and M98 P"config.g" in the gcode console tab of DWC?

Can you check the endstop status by sending M119?

@PhilippS invert your endstops. add a ! to each pin name on the M574 lines. e.g

M574 X2 S1 P"!xstop"

@jay_s_uk Thanks! It works now
@Phaedrux Tank you too!
