Biesseworks, setting up flycut

New job, New machine. Biesse Rover A. Noticed BiesseWorks is setup to automate flycut, assuming it drops the jig thickness automatically. Previous operators were manually adjust jig thickness and running a spoilboard program to resurface. Having no luck in finding the setting or options for using the flycut shortcut. Assuming need a prog, in a specific location for it to work, but can't find any documentation on how to set it up. Any help would be appreciated. Biesseworks 3.4 btw.

If you want to change the thickness of spoilboard in enabled dynamic thickness (=machine doesn't care about the jig thickness in program), you have to press PLC button "jig thickness" on console when machine is in Manual movements. it opens dialog window with current value of jig thickness.
So after every surface cleanning you should modify that value.
