How do I adjust steps/mm on UM2? All my parts are coming out a little too big. They are good in Cura, but the print is 2mm too big. Where should I look on the UM2 to adjust the steps/mm? Thanks in advance, ~Dusty

This time with pictures! This image shows Cura's dimensions of exactly 109.15mm from end to end (axis is through the screw holes). http://imgur.com/A6RAg3D This image shows the actual part comes out 110.83mm. http://imgur.com/lHBRrOS Which leads to the holes not lining up as seen in this image: http://imgur.com/1S9YpAg I did not notice any large gaps in lines, however I will be re-leveling the build plate before next print. Thanks, ~Dusty

I'm trying to make a part with some pretty tight tolerances between two screw holes. The dimensions look good in the design software (Blender), look good in Cura. But when I print, the piece comes out too big (by like 3mm across a 110mm piece). It causes the screw holes not to line up. Is this a problem with Cura's translation to gcode? Or is there a sizing/scaling issue on the Ultimaker 2? Are there any maintenance functions, utilities, or settings i should be looking for to make sure it prints accurately? Thanks in advance, ~Dusty.
