hi everyone,

i have a 3 axis machine and want to add a lathe/rotation axis, too but i can't add it as 4th axis because of the control card so i am thinking i can add it instead of Y axis.

so what i gonna do is unplug y axis connection from control card and plug new rotation axis cable.

so i need the gcode to have rotation axis values instead of Y axis ones, i assume i need to set it from "post-processor generator" window (when click edit for current PP) and under setup tab but couldn't make it work. any help on it?

thanks in advance.
