Changes made for Pathfinder V5 PC's.

What it does Adds a "Gripper Offset" panel to the one-step bend screen, positioned between the BG Position and Overbend columns. Contains:

"Gripper Offset" label "Select Backstop" button that opens the backstop selection dialog (Normal, Backstop 1, 2, 3) Below, the selected backstop value displayed in bold The selected backstop distance becomes the GripperOffset value in the OperationNormalBend that gets sent in the profile.

Visibility Only shows when HasBackstopExtend == true AND IsUpperBendingBeamEnabled == true (same conditions as the jog screen and calibration screen backstop buttons).
