I created a 1 inch square with CorelDraw 5x. I then exported the image to a .jpg. I opened the file in CNCC as an "pict" set advance and CREATEd the G-Code.
After running the printer, the completed print is NOT a square inch; it's bigger than 1 inch square. Clearly the printer is scaling the print to be larger.
WHY? What is the scale factor?
