Summary Moves to the home position and resets the device's internal position.

Upon receiving this instruction, the device will retract until its internal home sensor is triggered. It will then move forward several steps to avoid accidentally re-triggering the home sensor during use. Its internal position is then reset (to 0 for most devices). If a home offset has been specified with the Set Home Offset (cmd 47) instruction, the device will move forward for the specific offset, then reset the internal position.

Prior to Firmware 5.21, the device will attempt to home for an extended amount of time. For Firmware 5.21 and up, the home command aborts with an error if the device has traveled twice the Maximum Position setting without triggering the home sensor. This indicates that the device could possibly be stalling or slipping.
