5.5 HOMING
Homing the machine allows the Gantry to determine its exact position on the Runway. There is a homing
switch located on the Runway close to the Main Electrical Panel. When the machine is instructed to home
the Gantry will move slowly in the Home direction until the switch is energized and then reverse direction
until the switch is de-energized. If the homing switch is already energized when the homing command is
given, the Gantry will move in the Away direction until the switch is de-energized. Homing is required
whenever the computer is powered down and after certain faults occur. The Home button will display as
red when homing is required. If the machine will not Home itself check to see that the machine is enabled.
An improperly adjusted Head up switch will also not allow the machine to Home.

5.6 SCANNING
Scanning refers to the process of locating the position and shape of all lumber stacks in the system.
Scanning finds the position of the next board to be picked from each lumber stack and can identify empty
stacks. The data from the laser and the Gantry encoder are both used in the scanning process. A lumber
scan must be performed whenever the machine is restarted after being powered off. It is also a continuous
process whenever the Gantry is traveling. When the e-stop button is pushed or the Light Curtain is broken
you will be given the option of rescanning. If the lumber stacks have not been disturbed you may choose
not to scan.
