Using the 4x M4x55 countersunk screws, bed springs, and bed adjustment wheels mount the bed to the frame.

The bed wires should face the back panel

With the new bed adjustment wheels they won't work with the metal kit. I made some spacers so you can still use them. You can find them on my Github

Mount the bed frame to the Z brackets with 4x M5x10 button head screws and 4x M5 T-nuts

Feed the bed wires through the hole on the bottom left of the back panel
