Gear cutting groove in filament when printing "flat" terrain models

[brent113]

Some people have had better luck setting the final z height at the end of the calibration where it barely touches the card. Check this out from Atom:

First 3D print attempt pushes mat off the base

when your doing your height setting, don’t follow the directions, rather set it so you can just barely feel resistance on the card(no creasing). then if you have adhesion issues lower the Z offset.
