Getting Started
Safety first
Safety is your responsibility. Always use the
proper protective equipment and "safety
sense" when building or operating a 3D
printer.
Printers have high voltage power supply, and extruder operating temperatures can be over
200 degrees Celsius. The operator should understand the hazards before operating a
printer.
Required tools
Please browse through the instructions and get familiar with the steps before you
begin.
To put the kit together you will need:
a Phillips screwdriver for the screws
a pair of pliers to hold the nuts
a sharp knife or a pair of side cutters to trim the zip ties and string
sand paper to clean up the plywood parts and remove sharp edges.

Tools you may need for the electronic setup include:
soldering iron/solder
wire cutters
multimeter to correctly set up the power supply and stepper motors and general
trouble shooting.
For the printing you will want to have:
computer with a USB to program and run the printer
calipers to measure motion distance and extrusion width
calibration block STP file
Building the Printer
We recommend a large working surface for assembling the printer. The plywood
may require some minor sanding and can be painted, stained or finished for a different
look.
Extruder Assembly
Parts for the extruder mount assembly include:
A. 1 Extruder mount
B. 1 Extruder lock
C. 1 Extruder spacer
D. 3 M3 x 20 machine screws
E. 3 M3 nuts
F. 2 LM8UU bearings
G. 4 Large nylon ties
H. 1 Extruder

1. Place the bearings into the rectangular slots of the extruder mount.
2. Wrap the bearings by inserting large nylon ties through the side opposite of the bearing
into the slotted holes of the extruder mount.
3 Pull the bearing snug against the extruder mount (use pliers if needed).
4. Cut off the excess of the nylon tie.
For a clean look and string clearance, insert the nylon straps first in the inboard
holes.

5. Insert the 4 wires through the extruder mount from the same side as the bearings
through the wire slot.
6. Pull the wires through and re-coil them to keep them out of the way and undamaged.
7. Insert a M3 x 20 screw from the extruder side into the middle mounting hole.
8. Place the extruder through the extruder plywood mount.
9. Install the extruder spacer with the cut groove facing down..

10. Install the extruder lock to the extruder spacer with the cut groove facing down.
11. Insert the 2 remaining M3 x 20 screws into the holes.
12. Install the 3 nuts and tighten.
Y Sub-assembly
Parts for the Y sub-assembly include:
A. 1 Left mount
B. 2 Bearing holders
C. 1 Extruder assembly
D. 1 M3 x 16 machine screw
E. 1 Right mount
F. 4 M3 x 20 machine screws
G. 6 M3 nuts
H. V groove bearing 623VV
I. 2 LM8UU bearings
J. 12 Large nylon ties
K. 2 8mm rods

5. Insert the bearing and then the nut on the M3 x 16 machine screw.
6. Tighten the nut
7. Install the screw and bearing through the top of the right mount through the bearing
mounting hole.
8. Install and tighten the nut.
The bearing should rotate freely once installed.

9. Press in the 4 M3 nut into the slots on the bearing holders.
10. Assemble the left and right mounts to the bearing holders with 2 M3 x20 machine
screw.
11. tighten the screws.
Note orientation is important. The bearing center should line up with the hole on
the left and right mounts.
