When my Carvewright came friday I opened the box and set it all up as per the instructions. It said there was a stop flag under the tape on one side Iinside) but I found nothing under the tape. Is this the same thing as what the manual calls a homing flag? I did find a small piece of steel in the bottom of the box. Maybe 3 inches long, 3/8 inch wide bent at about 45degree angle along the length and it has a small extension on one end like a flag. Is this the stop flag? If so where does it go? I DID find a plastic slot on the inside key pad side that it seems to fit into but does it go flag up or down?
