Once done there will be a slight drag while

A small amount of brass bushing (MST0866)
should still be exposed at the bottom. This is
called an Anti-backlash nut that is used to
remove play or slop in the Z-axis.

Assemble to Back and Base Panels
Insert the print platform onto
the shafts of the back panel
as shown.
Turn the lead screw so that we
have approximately 2 inches
exposed from the top.
This will help to align with the
bearing.

The movement of the bearings and rods will
feel tight at this point, but we will tram (align)
the system later.
Slide the print platform upwards so that the
Z-axis lead screw inserts into the bearing.

Now install the torque coupling to the bottom of the lead screw.
Positioning of torque coupling is not critical.
But at this moment, leave approx. 3mm distance
(for tramming procedure later) between bearing
support and the coupling.
Then tighten the coupling’s UPPER screw only.
Leave approx.
3mm gap for
now

Next we are going to assemble the back panel
to the bottom panel.
It is recommended to turn the back panel on its
side and slide the bottom panel in place
(making an “L” shape)
As you slide the bottom panel up you will need
to align the torque collar to the stepper motor
and the 2 vertical rods into the base.

With the back panel and bottom panel attached reposition the frame vertical to the upright position.
At this point we need to start to tram or square up the mechanics to ensure a smooth bind free motion

Tramming Back and Base Assembly
We need to check the start friction, turn the torque coupling (that is at the bottom of the lead screw)
that we just installed left and right a few times, you will notice a heavy drag and possible binding on
the print platform just make a mental note of how much strength it takes to rotate the rod.
During this test the lower clamp to
stepper motor should not be tightened
so that the motor is not rotating and
only the drag of the rod is felt
Now to fix this problem, refer to diagrams 2.2a to 2.2c and loosen all the noted screws
in order.
Loosen them just enough that there is no contact with
the screw head and frame (Example on the right).
First loosen these 7
screws at the back
Then loosen these screws on
BOTH sides of print platform

Now following diagrams 2.2d to 2.2g for tightening order (The sequence is critical), go
through the hardware and re tighten the screws
Then loosen these 4 screws on

Tighten these screws on

By loosening the hardware the mechanical parts can adjust
to their natural tension-free positions alleviating binding.

Finally, tighten these 3
screws at the back
After following the above tightening sequence the build platform will
move much easier and this can be verified by now turning the torque
coupling again and feeling a reduced amount of force needed.
Try turning the torque coupling again
after the above procedures
There will always be some drag as this is calculated
to remove play and slop in the system.
If you are not satisfied, you can do the procedure again

Now that the first components are trammed we need to secure the torque coupling to
the stepper motor.
Loosen the coupling from the lead screw and slide it down so that there is an equal
distance top and bottom from the lead screw and motor (shown below).
Then tighten both ends of coupling

Next we are going to install the side panels. The side panels have a few things we need to
pay special attention to.
Both sides have the forward print platform vertical rods. This requires us to install the side
panel by sliding them down from the top.
The left panel (DSA3302-U06) has the A/C receptacle that needs to be attached from the
inside using some screws and nuts before we slide it down making installation easy to get to.
Place Side panel close to printer bottom
so we do not pull or damage the AC wires
from the power supply

With the power switch / receptacle installed in the panel, it’s time to install the left panel by
carefully sliding the vertical rod down the front print platform bearing (pictured below right)
and making sure the rod aligns with its lower mount (pictured below right bottom).

Now check to make sure no wires are loose or damaged to the Switch / Power receptacle
to the power supply. Now well, we have easy access to the power supply, let’s set the
voltage.

Power from your home outlet varies depending on
where you live, for example, the USA is 110V
while Hong Kong is 220V. There is a switch on the
right side of the power supply marked 110-220V
(see above picture).
Set this switch to the appropriate position for your
region. If you are unsure about any of the above
steps or specification consult with a qualified
professional electrician.

Great job! Let’s move on to the right side panel. This one is easier than the left side, we
will install it in the same way as the left and loosely install the screws as we did on the right.
Make sure as you are installing the
right panel the sensor wires do not
get pinched or caught on anything
