WARNING: This is a warning. Information in these boxes is VERY important. Pay close attention.
WARNING: When moving the gantry by hand, go slowly. The power generated by the stepper motors
will feel like bumps. If the lights on the Carbide Motion board are lighting up, it’s very important to slow
down because you are pushing electricity back through the board. Too much back ow could damage
the Carbide Motion board.
NOTE: This is a note—information that points out critical steps or information for future reference.
PRO TIP: This is a pro tip. Anytime you see one of these, you will nd helpful additional information.

PRO TIP: Use a spare hex key or two to
align the middle three screw holes. See
Figure2‑5. To further help with hole
alignment, shine a ashlight under the
assembly to illuminate the holes from the
bottom. Adjust as necessary.
NOTE: If you are having trouble getting any
of the endplate screws to line up, try starting
from the center and alternating your way out
to the ends. Apply a little more downward
force, but be careful not to cross-thread.
Screws may t tightly but they should not
wobble when turned. Still having trouble?

ECCENTRIC NUTS AND V-WHEELS EXPLAINED
Eccentric nuts and V-wheels are what we use to adjust the gantry at the intersect between the carriage V-wheels
and the V-rails. A loose connection here is referred to as carriage slop. To eliminate slop, a very small amount of
tension is added between the wheels and rail. Too much tension and the wheels will deform, causing bumpy and
constrained motion. Not enough tension, and the carriages will wobble. When tension is just right, the carriages glide
smoothly and without slop for the highest-quality cuts.
Our HD eccentric nuts, in combination with the attached V-wheel, operate as a cam, converting the rotational motion
of turning the nut, into linear motion at the V-wheel. A dimple on one the side of the nut indicates the furthest point to
center of the offset threads. When the dimple is facing UP, the distance between the top and bottom wheel is at its
greatest and the V-wheels are OPEN. When the dimple is facing DOWN, the opposite is true, and they are CLOSED.
See Figures 3‑4 and 3‑5.
When adding tension to a loose V-wheel, turn the eccentrics clockwise. Turning counter-clockwise will loosen the
bolted connection between nut and wheel. If this happens, re-tighten with a 10mm wrench and a 3mm or 4mm hex
key.
Not much tension is needed for the carriages to be secure. The wheels should only be snug against the rail. Reach
under and spin the V-wheel with your nger. If it rotates freely, turn the eccentric nut clockwise until you feel some
friction against the rail and the carriage is free from slop.

1. Place the X-rail, with the decals facing the
front, across the top of the two empty Y-Axis

idlers, and motor pulley will be facing out as shown
in Figure3‑16.
3. Snug the Y1-carriage to the X-rail, but do not
fully tighten the screws.
Install the Z‑Plus
1. With the router mount facing front, line the
four V-wheels up with the two V-rails, and
slide the Z-Plus onto the open end of the X-rail.
See Figure3‑17.
Pay special attention to all four V-wheels making

Y2-carriage to the open end of the X-rail. See
Figure3‑18.
When properly attached, the motor body will be

3. Snug the Y2-carriage to the X-rail, but do not
fully tighten the screws.
NOTE: Each extrusion rail has a pair of
V-rails running the entire length of one side.
These V-rails serve as linear tracks for the
V-wheels, securing the carriages to the
gantry and allowing them to glide smoothly.
The V-rails will face to the front (X) or inside
(Y1 and Y2) of the machine. See Figure 3‑14.
PRO TIP: Screws going into the ends of the
extrusion rails are prone to cross-threading.
Pre-screw without the carriage to clear
any debris from the threads. Screws should
thread easily, with little resistance and
without wobble. Also, when attaching the
carriage, partially insert each of the four (4)
screws before tightening. Then tighten each
a little at a time in a cross-pattern.
PRO TIP: Use masking tape to prevent the
Z-Plus from rolling back and forth along the
X-rail and hitting the other carriages.

Belts and Belt Clips
Belts are secured to the rails using belt clips. Each belt clip has an PEM nut on the short leg and two parallel
slots on the long leg. All six belt clips will attach to the ends of the three belts as follows. See Figure5‑4.
1. Thread 2 /inches of belt through the outer slot of the belt clip with teeth facing toward the PEM nut.
2. Loop this end of belt down and through the inner slot of the clip. Pull the belt tight against the belt clip.
The length of the short end should now be about 2 inches.
3. Bring the two sections of belt together. Interlock the teeth and extend the belt away from the PEM nut.

NOTE: To accommodate the smaller Shapeoko 3 machines, the Y1-motor is mounted to the
Y1-carriage with four (4) M5x10mm socket head cap screws. However, to attach the Y-Axis drag
chain head bracket to the Shapeoko XL, the top two (2) motor-mount screws will need to be replaced
by two (2) longer M5x16mm socket head cap screws. Once replaced, the shorter screws will no
longer be needed. See Figure 6‑6.
