Core XY - Y Homing not functioning correctly

@wharris87 said in Core XY - Y Homing not functioning correctly:
After the Y axis has 'homed' DWC gives the y position as '350.00', even though it hasnt even moved towards the end switch, let alone touched it!
use M119 to verify your endstop configuration
https://duet3d.dozuki.com/Wiki/Gcode#Section_M119_Get_Endstop_Statuspress it by hand and issue the command and see if the status changes.

thanks for you replies - I have just updated firmware to 3.0

The status of the y endstop is not changing when being pressed or not.
This suggests a wiring issue.
Time to break out your multimeter and get testingOwns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

@wharris87 said in Core XY - Y Homing not functioning correctly:
have just updated firmware to 3.0
please now update to 3.1.1
-
@jay_s_uk love a big of rewiring! but would this explain how/why the indicator light on the board changes when the switch is pressed/depressed?
-
@wharris87 no, it would not, so theres definitely something dodgy going on.
Is it plugged into the correct port? -
@jay_s_uk im assuming the light wouldnt be coming on if it was plugged into the wrong port?
-
The lights function regardless of whether the endstop is configured in firmware or not.
maybe a photo would help? -
To quote my initial post... 'its either the board, or im being really stupid'.
It was the latter; i had the y stop plugged into the 'E0 Stop' port, which meant 'a' light was switching on/off, but it was the wrong one!; helps if i read the very helpful text etched onto the board!!
Thanks for your help everyone!

@wharris87 Glad you got it sorted!
