Z homing in wrong direction

Yveske

After changing to the beta version of the CNC UI, the Z axis always goes down towards the spillboard during homing instead of up.
Changed M574 Z2 to Z1 and back with no avail.

; Drives
M569 P0.0 S0                                ; physical drive 0.0 direction (0 = backwards, 1 = forwards (default 1))
M569 P0.1 S0                                ; physical drive 0.1 direction (0 = backwards, 1 = forwards (default 1))
M569 P0.2 S0                                ; physical drive 0.2 direction (0 = backwards, 1 = forwards (default 1))
M569 P0.3 S1                                ; physical drive 0.3 direction (0 = backwards, 1 = forwards (default 1))

; Endstops
M574 X1 S1 P"!io0.in"                       ; configure active-high endstop for low  end on X via pin io0.in
M574 Y1 S1 P"!io1.in+!io2.in"               ; configure active-high endstop for low  end on Y via pin io1.in
M574 Z2 S1 P"!io3.in"                       ; configure active-high endstop for high end on Z via pin io3.in

Hi,

The direction of homing is controlled by the commands in your homeZ.g file.

Please post that.

@fcwilt
Thanks for pointing me in the right direction. Problem solved !!!
I do wonder how it ever could have worked before...

Glad to hear you got it working.

A combination of telling it to move in the wrong direction but also having the motor rotate in the wrong direction.
