one advice i want give you ,very very important
you MUST think and give solution while M6 running ,if m6 stop in middle
because in mach if you press stop while m function run or its stop from any other reason ,its not stop at all the function
its only stop the movement
so for example if you stop before you release the tool ,the machine not move any more ,but the tool will fall
SO you must give attention in any output activate to be sure what is the machine status bfore do something
