Hi all,
I would like to apply geometric correction for surface unevenness of my CNC router table.

Before changing the Z values, I tried applying the following geo file to see what happens:
2,2
1,1
0,0
0,0,0,0,0
0,1,0,1,0
1,0,1,0,0
1,1,1,1,0

I thought there would be no transformation at all on X and Y, but when I jog the Y+ direction (up) in KMotionCNC, my gantry goes in the X+ direction (right). Similarly:
Jog X+, gantry goes Y+
Jog Y-, gantry goes X-
Jog X-, gantry goes Y-

I have spent several hours testing and have read through the manual, but I can't make my machine behave correctly. I am not sure if it is related to my axis output gain settings, which are 1 for x, -1 for y and -1 for z axis.

Your help will be highly appreciated. Have a nice day!

The values in the table are:

Row Column X Y Z

so for example row=0 column=1 would be the grid position one column to the right in X. So would be:

0,1,1,0,0

not

0,1,0,1,0
