Locate the anti backlash nut (ABN). The ABN
will come with (2) M5 nylock nuts, a M5 grub
screw, and a M5 jam nut in the bag. Push
the nylocks into the hexagonal holes on the
face of the ABN with the nylon facing up.
Screw the grub screw into the top of the ABN
until it touches the bottom through the gap.
Cap the grub screw with the M5 jam nut. Place the ABN on the z plate and
secure using the (2) M5x20 machine screws. Make sure the nylocks can be
seen.
Locate the Z rails with bearings.
The bearings will slide off the rails expelling
all ball bearings. Please proceed with caution.
The rails will have plastic or
rubber blocks to keep the bearings from sliding off. Leave them in place
until told to remove them. If the blocks are not present, tape both ends of
the rails to keep the bearings from sliding off. Place the Z rails on a flat
surface with the bearings face up.
Place the Z plate on top of the bearings lining up the bearings with the 4-
hole groups on the corners of the Z plate. The ABN should be on the same
side of the Z plate as the bearings. Secure the Z plate to the bearings using
the M3x10 button cap screws. If you have purchased the Homing Switch
Option, Locate the Z engager bracket. Secure the bracket to the Z plate
with M3x16 machine screws using the two bottom holes of the 4-hole
group at the top right of the Z plate. The indention on the Z plate is the top.
