FROM THE BACKSIDE. Slide an M6 split-lock washer onto the bolt, then thread on an M6 nut.
Looking down at the X Axis Bearing Plate in the orientation shown in the above diagram, you
should see the threads pointing at you, an M6 nut, an M6 split-lock washer, the X Axis Bearing
Plate, an M6 flat washer, then the M6 bolt head. Do the same with the hole labelled (B) at the
bottom of the plate. Remember, these bolts should be pointing TOWARDS you.
There is only one hole labeled (C). This bolt will also point towards you when looking at the front of
the X Axis Bearing Plate. You’ll need an M5x30 screw, two M5 washers, two 625 bearings, one M5
Nylock nut, and one 10mm aluminum spacer. BE CAREFUL WHICH SPACER YOU PICK UP HERE. THE V
WHEELS USE A DIFFERENT SPACER (6.35MM). THIS SPACER IS LONGER THAN THOSE. Slide an M5
washer onto the bolt and insert the bolt through hole (C) from the backside. Now slide the 10mm
aluminum spacer onto the threads, followed by a 625 bearing, an M5 washer, another 625 bearing,
and top it off with an M5 Nylock nut. Get this nice and snug, but don’t go crazy. Bolts can bend if
overtightened. As you look down at the plate in the same orientation shown in the diagram, you
should have the Nylock nut, a 625 bearing, an M5 washer, another 625 bearing, the 10mm spacer,
the X Axis Bearing Plate, an M5 washer, then the head of the M5 bolt.
Now grab a NEMA 17 stepper motor so you can install it at the top of the X Axis Bearing Plate. You
will mount it with M3x8 bolts in the four holes labeled (D). Take special note that wires coming out
of the motor should be pointing towards the bottom left when you install the motor. Look at the top
of the diagram. There is a top (D) hole, a right (D) hole, bottom (D) hole, and left
(D)
hole. You want the wires on the motor to be sticking out between the left (D) hole and the
bottom (D) hole. Slide an M3 split-lock washer onto an M3x8 button head bolt and install the
motor. Looking down at the X Axis Bearing plate in the orientation shown in the above
diagram, you should see the M3 bolt head, M3 split-lock washer, X Axis Bearing Plate, then the
stepper motor body. The shaft of the stepper motor will be pointing up at you in this
orientation if you are looking down at the X Axis Bearing Plate as shown in the diagram above.
If you purchased the homing switch kit, you will install an M6x40 bolt in the hole labelled (E).
There is only one such hole.
Slide an M6 flat washer onto
the M6x40 bolt, insert the bolt
into hole (E). Secure the bolt
using an M6 split-lock washer
and M6 nut. Looking down at
the X Axis Bearing Plate in the
orientation shown in the above
diagram, you should see the
head of the M6 bolt, then a flat
washer, then the X Axis Bearing
Plate, then an M6 split-lock
washer, then an M6 nut.
