| On the other hand, the floating head system simply requires an **INPUT** to the controller to indicate that the button has been pressed. It does not need to be retracted or turned off when the cutting commences, so no OUTPUT from the controller is needed. Therefore, in order to set up the IHC system within the myCNC software, the user needs to assign at most two connections (or sometimes only one, in the case of the floating head mechanism). | On the other hand, the floating head system simply requires an **INPUT** to the controller to indicate that the button has been pressed.

It will then wait at this ignition height until it receives the Arc Sensor input, and will then proceed with the pierce and the THC sequence. |
