There are several ways to do this but try changing the scale sign ie put a - in front of scale in the INI file

Edit I was thinking you wanted to reverse the direction of the motor

I'm not sure that's a good idea. It goes against convention.
You could move your home position to the upper R corner and continue using conventional coordinate system no?

I had the same issue, i needed to reverse my Y axis, so i set the Y home at the max travel minus 10mm
When homing i get X=0-10 and Y=1220-10

At least it keeps the XY orientation standard

Do you want to invert the movement or invert the visuals?

What version of linuxcnc do you use?
Is it an installed version or a developer version?
what screen are you using?

well plasmac axis and plsmac gmoccapy are a little different change.
You will need to hand modify a python file and if you update will probably have to modify it again.

/usr/lib/python2.7/dist-packages/glnav.py

look AXIS for :

    def set_view_z2(self):
        self.reset()
        glRotatef(-90, 0, 0, 1)
        mid, size = self.extents_info()
        glTranslatef(-mid[0], -mid[1], -mid[2])
        self.set_eyepoint_from_extents(size[1], size[0])
        self.perspective = False
        self.lat = 0
        self.lon = 270
        self._redraw()

change the one line to:

        glRotatef(-180, 0, 0, 1)

save the file and one of the Z views will be as you requested.
