I am using currently the Makerbot (3.10.0.1364) software as slicer.
On most of my prints there is a problem with the lower 5-6 mm, primarily if there the part has rounded corners.
I print mostly in ABS at 230C extruder and 110C platform temperature with a medium (0.2mm) resolution.
Anything above this problem-zone comes out OK and has the correct dimensions.
Any suggestions are welcome.
