Many of the settings here are automatically set from machine settings when Import Machine Files is performed.
Command to Set Gripper State, eg M45 or M46%s%s%s%s, gripper control words are passed in with %s
Number of back grippers; usually 2 or 3
Number of side grippers; usually 1 or 2
Independently Retractable Back Grippers
True if back grippers can independently clamp and retract (each back gripper is mounted from the end of a retractable cylinder)
Minimum spacing between side grippers
Min Side Gripper Plate Position
Minimum X Plate coordinate of the side grippers, when the back grippers are engaged.
Prevents collision with back grippers.
Max Side Gripper Rail Position
Maximum X machine coordinate of the front side gripper (at its forward limit).
Measured relative to the machine's laser pointer.
Max Back Gripper Rail Position
Maximum X machine coordinate of the Back grippers (at its forward limit).
Measured relative to the machine's laser pointer.
Maximise Back Gripper Span? (Default: True)
If True it will always try to keep the backgripper farthest from the side grippers within the plate extents engaged
This will result in more gripping and ungripping of the topmost backgripper when enabled but may be better for reducing plate slippage.
Without this being set, the program may ungrip an outer backgripper by necessity, for example to drill a hole near that gripper, and having done so will continue on leaving it ungripped as the configuration it has is "satisfactory" but not necessarily ideal. With this set, the program will immediately re-grip the backgripper as soon as it can.
Allow Side Grippers Only? (on narrow plates) (Default: False)
If true, Gripper Plans with no back grippers engaged will be allowed.
Only effective if the plate spans one or zero back grippers.
Setting to True increases risk of plate slipping in the side grippers.
