Z bed leveling with BL touch moving Y axis instead of Z
-
Hi everyone, i'm building a printer based off ender 3 pro with a duet2 wifi. Printer seems to be working fine besides this problem with bed leveling. When I tell it to home z / level bed it will move the y motor instead of z, if I trigger the probe manually it will think that its leveled correctly. Making me think there's no wiring issues as all axis home correctly. I've been through the config files over and over, also tried alternatives but nothing seems to fix it. Any help would be much appreciated so I can move forward with the build cheers!

if you carefully put the printhead where it can move somewhat while the machine is powered off, and then test motion with moves from the Console tab like this:
G91 G0 H2 X5 ; needs 5mm or more space to move G0 H2 Y5 G0 H2 Z5Do the right axes move?

@oliof Appreciate the reply, seems as if they were plugged in reverse with end stop too, making it seem like it was set up correctly. It's always the simplest things right, thanks mate!
