Subject: [PATCH] g-code defaults to mm not meters, allow offset

g-code generally defaults to millimeters, but Dexter takes in meters. A default value for a scale factor of 0.001 corrects this issue and allows scaling to be changed. Also include an offset in x, y, and z to help it work in a better area.
