	If a secondary tool is mounted adjacent to the torch head, to be used in conjuction with cutting operations, it will need to extend and retract independently. A small air cylinder could advance the secondary tool to a fixed-location "extended" position (hard stop) well below the torch tip, and retract it to a clearance position well above the torch. Finer adjustment is the role of the Z axis. The secondary tool retraction does not require any precision slide as long as the final extended position is firm and repeatable.

	A common issue with torch tables is that once a part (or a waste slug) is cut loose, it can tilt up. The tilted-up part can be high enough to interfere with the tool while it is moving around. Some commercial torch mounts even have a "breakaway" feature for protection. If the secondary tool actuator is on an air cylinder drive, it could retract very quickly if a collision is detected.
