I've read the Mach3 manual and I'm a little confused. I have a permanent laser center finder attached next to my router and I have the x and y coordinates from center of the router bit to the center finder. I want to be able to just use the laser and then zero out and run a program and have it know that 0,0 is actually x-1.2 and y2.3. Do all I have to do is put those coordinates into the G55 box in work offset, then when I run a program it will automatically compensate? Also do I need to set that G55 code in my CAM program or will Mach automatically add that part in?
