3.3.2.1 Homing First
Whether homing is required before executing the working program. If this option is not select, it means after turn on the machine, it will not return to homing, before operate the work, because, if homing is not done first, when the machine first turns on, the position of the tool will be considered as the machine origin point. Position of each reference point will move with the movement of the machine origin point. During this time, if you are not aware and use reference point for relevant command, it could likely cause clashing to the work piece and cause damage to the work piece or the machine, so we must inform the user about it. Also, handwheel control, is not in the selection limitation, press F4 for control. If system encoder mode is in absolute mode or incremental absolute mode, you cannot choose this option, the system does not need to return to home, to find the correct current position.
