The tension of the extruder can be easily adjusted via the screw pictured below. Turning this screw clockwise (right) will reduce the tension, while turning counterclockwise (left) will increase it. Dialing this in should help remedy most FMS and extrusion issues.
turn left = tension increase
turn right = tension decrease
