Step 6
Take the Hot End Clamp and push a M3 Nylock nut in to the recess on the side. Secure with a
40mm M3 Bolt and M3 Washer. The clamp can be very tight, this is to ensure the hot end stays
in place. You may find it useful to use a longer M3 bolt. There will be one in the spare parts
bag. Leave the clamp loose.
Push two 50mm Hex Top Bolts through the base of the extruder so the heads locate in the
recesses. Slide the Hot end clamp on to the Hex Top Bolts. Ensure that the clamp opening is
on the same side as the extruder gear. The clamp only fits on to the X Carriage one way so if it
is the incorrect way round, your Extruder will be mounted backwards.
