Linear positioner

A linear positioner, comprising:

• a table elongated along an axis and including two or more discrete table sections coupled to one another end to end, the table having a deck to support a workpiece and a fence to orient the workpiece on the deck;
• a stop to contact an end of the workpiece;
• and
• an actuator configured to drive the stop along the axis in response to a signal(s) from a computer, to position the stop at a desired position,
• wherein the actuator includes a carriage for the stop, wherein the table includes a track to guide travel of the carriage, and wherein each table section provides a segment of the track.

A linear positioner, comprising:

• a table including a track, the table being configured to support and orient a workpiece parallel to the track;
• and
• a shuttle including a stop to contact an end of the workpiece and a motor to drive the shuttle as a unit along the track, in response to a signal(s) received from a computer, to move the stop to a desired position,
• wherein the shuttle includes an antenna connected to a controller and configured to receive radiofrequency signals from the computer, and the shuttle includes one or more onboard batteries configured to supply power for operation of the motor.
