S3D printer profiles setup include steps per/MM
If the ratios have changed within the mechanism of the printer between 2 and 2+ then it would have an effect. I've never had a problem to this degree with ABS. I know it shrinks but never had this much.

Just wondering what has to do the steps with using s3d??
Btw steps per mm might not have nothing to do with that since um2 machines use gt2 80steps for x/y.
The size difference can be just because filament contracts when cools down, some filaments more than others. Also there's a different in size for holes than for exteriors due filament deposition. Print some cubes for each filament/temp used and design profiles to compensate the design.
