So ... a lot of coding and finally I'm very close to the end... Attached you can find the manual, 2 axes operations already tested and even lathe operations and 3 axes operations, now I will start the testing for 4 axes operations... 5 axes operations can't be tested because I don't have yet a 5 axes machine, I can only import in a gcode 5 axes simulator . As soon as I will be sure that everything is done I will release it.
