I am the new owner of a used Epilog Mini 18 and have a question about the home position. If I turn on the red dot pointer it points to a position close to the left side ruler and about 3/4 inches down from the top ruler. This is where it returns to if I press the reset button also. Is this the normal home positon? I expected to be in the upper left intersection of the rulers. If this isn't the home position, how do I change where it goes when the reset button is pressed?
