I dry ran a cube; this is the first few layers of a 20mm cube. This is basically what I tried printing the last two times that over exposed 5-10mm out from the edges of the cube. I cleaned up some of my code and don't think I'm going 35x35mm anymore, and seem to be within .05mm of size based on my gcode processor. The part that does go outside is my slicer has a skirt around the print which is common for PLA/ABS prints. https://www.youtube.com/watch?v=0kGSB5FVPKk
