I need to make sure the center dot is actually in the center of the engraving area (75mm X&Y).
I need to ensure that the Live Preview and the actual engraving are the same. Specifically, I know that right now the engraving is exactly 100mm x 100mm, but the Live Preview is smaller by 2mm on the Y access and 1mm on the X access. The Live Preview is also not centered on the engraving, it is indexed off the upper left corner of the square, see the pic below.
I think the video you posted is what I need, I will give that a shot this evening.
Thanks again!
