I made a diff, how i swapped zy on my machine. I also made this ini variable to limit some behaviour of subroutines, depending on vertical or horizontal operation.
[V_H]
VH = 1 / VH = -1
Normally, I use the vertical head, which bolts on to the Y axis. But If I remove that vertical head, there is a second SK40 spindle directly in the Y axis, facing straight forward, so in that configuration, Y become -Z and Z becomes Y.
Cheers,
Mark
