4.6. Back to Machine Origin
Origin of Machine Coordinate System (the inherent coordinate system of a machine tool), also called
machine origin, mechanical zero, or home, is fixed after design, manufacturing and debugging before
the machine tool leaving factory. Only after backing to machine origin can such operations as soft limit,
setting fixed point and tool change be enabled. Therefore, after startup of CNC system, it is necessary to
home all the axes. This system will remind to back to machine origin after start-up.
If homing can‘t be executed due to home switch fault, it is necessary to set the parameter ―Back REF
First
‖ to ―No‖.
