2 – Installation of the Heated Bed
2.1 - Identify the nine holes in the top marked with a laser engraved “1”. These holes are where
you’ll install nine #4-40 T-Nuts from below. The simplest way to seat the t-nuts is to use one of
the heated bed mounting screws and a washer to pull the t-nut into place. Place a t-nut into
one of the correct holes and thread in a #4-40 ¾” socket head cap screw with a washer on it.
Tighten it down until the tiny prongs have penetrated fully into the Melamine. If you’re building
an Acrylic version, flatten the prongs with your needle nosed pliers and tape the t-nuts in place
with a bit of scotch or other tape.
2.2 – Attach the heated bed to Mount Bed Insulator (P/N: 68335) using eight #4-4 ¾” socket
head screws. Set a small plastic spacer over each of the mounting holes that you installed a #4-
40 t-nut into. Set the heated bed & Bed Insulator in place. Make sure that the solder pads for
the heated bed are oriented towards the slot near the Z axis as shown in the below.
