Tighten the fastener until it begins to compress the flexy bed foot and the foot can no longer rotates easily.

attach flexy bed feet to all 4 y corners

7 Assemble Bed Mount Table & Y-Corners

Place two extrusion [HD-EX0062] horizontally with two T-nuts [HD-NT0053] in each extrusion.

Place the Y bed mount table [PP-GP0395], as shown, with the first layer print surface angle facing each other.

Secure the bed mount table with a [HD-WA0040] M5 washer and [HD-BT0073] M5x10 screw. These fasteners do not need torque applied yet; they will be adjusted during Final Assembly.

Insert one Y corner right [PP-GP0364] & one Y corner left [PP-GP0365] on each extrusion, as shown in the example photo.

Secure the Y-corners using T-nuts [HD-NT0053], M5 washer [HD-WA0040], and M5x10 screw [HD-BT0073]. Repeat for both sides and torque these fasteners to 5in*lbs
