I am just starting to use a resin printer. I have a scaling problem.  I'm printing an .stl file created on 3D Builder.  When I print this file on a Ender 5, the dimensions come out accurately.  When I print this on an Elegoo Mars 2 Pro, the dimensions of the print come out wrong.  For example, a part with a dimension in the software of 48mm came out at about 52 mm.

What am I missing? Is there a scaling factor built into Chitubox that I haven't come across?
