I am trying to get accurately sized prints, including inside dimensions.
Right now, I'm using a 20x5mm cylinder with a 10mm square inside hole as a calibration piece (file attached).
I priny a piece 19.6mm in diameter, 4.55mm high, and 9.69mm on the inside.
Looking at the gcode, the nozzle moves 10.482mm with a .52mm extrusion width, making a 9.962mm hole.
At the top, the gcode file includes the line:
"; A 10mm square inside hole measures 9.42mm (~ the same as an extra perimeter)."
Does this always happen? Is there any way to make a 10mm square inside hole measure exactly 10mm, with a tendency to be too large rather than too small?
I am using Slic3r 0.9.10b with a .35mm nozzle, blue Protoparadigm ABS.
