Help, my laser is not cutting to scale

Finally got my design to the point I was ready to make my first part and the part is way to big. The design calls for 28.4 mm diameter, the actual part is 34.6. I tried scaling the part in device settings but still the same size. Do I need to create a new/revised cor file? Thought that the laser was all dialed in by the manufacturer, but this does not seem to be the case.

Ok this works for gantry systems will it also work for Galvo?

Not certain but I’m betting the Scale portion might be worth looking into.
I don’t own a Galvo… yet… Ha!
