Abstract
An excavation system is disclosed as having first and second actuators configured to move a work tool in first and second directions. The second actuator may only be capable of full-range movement when the first actuator is positioned within a sub-range. The excavation system may also have first and second sensors configured to generate first and second signals indicative of first and second actuator movements, and a controller in communication with the first and second sensors. The controller may be configured to command movement of the first actuator to the sub-range, to confirm that the first actuator has moved to the sub-range based on the first signal, to command movement of the second actuator to an end-of-stroke position after the first actuator is confirmed to be within the sub-range, and to selectively record a current position of the second actuator as the end-of-stroke position based on the second signal.
