Stepper motor problems Duet 2 Wifi on Ender 3 Pro
Haike last edited by Haike
I have installed this Board on my Creality Ender 3 Pro. (Cartesian style)
I have contact to the board over wifi trough my browser and i can upload configurations from: https://configurator.reprapfirmware.org
When i make my configuration and uplaod it to the board, i can set temperature for my heat bed and nozzle, as well as make the fans trigger.
But when i try to home my X Y Z i am not able to do so with X and Y. when i press "Home X" or "Home Y" z raises a bit(as it should i assume) and the axis starts moving home. But when it reaches the end stop switch, the motor does not stop like on the Z Axis, it keeps trying to go further while it's all jammed in the process. i turn off the printer asap when this happens.
i have tryed multiple end stop configurations without luck, and even the same configuration as my Z axis have.
For all directions(XYZ), the End stop LED will change state when i press it, as of now, the LED goes OFF when the end stop is pressed.
The plan was to use the stall functionallity but i'd like to make it work with the simple end stop switches first. Or even better, work at all
Does anyone have a clue what could be wrong?
Board: Duet2 V1.04a
I hope this was sufficient information, when i got the board in december i updated it to make it ready for the printers arrival.

I don't know what endstops the Ender 3 uses, but my first suggestion would be to change them in your config.g to active low. Easy quick check and it won't do any harm if you have your finger over the power switch when you try it.
If the motors don't move at all, then you had it correct with active high.
You can use this to test your endstops. https://duet3d.dozuki.com/Wiki/Test_homing_behaviour

the end stops is normal switches with that little spring on that hits the switch itself
I tryed to set it to active low, the steppers then try to go further when it hits the end stop still
Have you seen this to setup your homing files?
Are you sure the motors are going in the right direction and hitting the right endstop? What happens if you press the other endstop switch manually?

Okay, this is embarrasing,
I have switched the stepper motor cables around for X and Y... not the end stops.. all day i have been starring on this board to see what was wrong.. and it's maybe just that i think.... oh no
