The I-Mark systems have an option to program how often the marker returns to the Home position, this feature is found under the properties tab on the machine window, as depicted below:

This screen show the "Home Marking Active" option as "yes". This means that the marker will return to the home position every cycle. Or as in the case shown on the screen the marker will return to the home position every 10 cycles. If the "Home Marking Active" option is "no", the marker will never return to the home position.

 

CMT recommends that the marker be returned to the marker to the home position every 100 cycles if the mark location requires a tight tolerance.
