Home Built CNC Laser Build Log
It took me a little while to figure out how to setup the resolution for the A axis (I am not a lathe guy) .. You set it up as steps per degree.. My setup is 200 steps/rev * 10 microsteps/step / 360 = 5..556 step/degree.. You then tell Mach3 to use tangential control and set a few items: Lift Angle and Lift Z..
