9.3 Leveling the Print Bed
9.3.1 System Description
Your F400 has 2 bed leveling systems: a manual leveling system and a sensor to detect the level of the bed and
compensate for it during a print. While getting the bed exactly level is not critical to printing on your F400, you will
get best results if the bed is level.
On the bottom of the bed plate you will see a small red thumbscrew at each corner of the bed. This is used to
adjust the height of the bed corner.
Turning it counter-clockwise will lower the bed corner. And turning it clockwise will raise the bed corner.
