WARNING

SHOCK

There is a danger of electric shock.

Use only undamaged electrical chords.

DO NOT touch bare wires or receptacles.

DO NOT touch the 3D printer or chords if hands
are wet.

Ensure that all cords are free of damage before
connecting to the power supply.

Ensure that you have a sufcient electrical supply for
supporting the requirements of the motor.

RISK TO BREATHING

Always use your 3D printer in a well-ventilated and
clean area.

Gas emitted by melting of Polylactide (PLA) or
Acrylonitrile butadiene styrene (ABS) can contain
contaminants that are harmful to breathe.

Never breathe the air that comes directly out of the
hotend. This air is not suitable for breathing.

If you feel ill from breathing while operating your 3D
printer, stop and seek medical attention immediately.

!

WARNING

Fragile

Electrical pins and sensors are delicate. Handle with
care.

Unless instructed, DO NOT force components together.

Read the instructions carefully to prevent damaing parts
during assembly or operation.

Before you Start

Before you attempt to assemble any of part the Ditto / Litto 3D Printer, it is imperative that you
read the build instructions fully and ensure you understand every part of the instruction.
While Tinkerine Studio provides warranty for all parts of the 3D printer, this does not cover damage
caused by not following the instruction manual or other end-user error.

Go down the BoM (Bill of Material) and tools checklist and ensure that you have all the
required parts to assemble the Ditto 3D Printer. Extra screws have been included into the kit.
If you nd anything missing, please contact us via e-mail at [e-mail]

Give yourself plenty of room and clean space during the assembly process. This prevents
delicate components like the electronics or bearings from being damage by dust or blunt force.

To ensure proper alignment of the panel and overall rigidity of the printer, it is highly
recommended that the assembly is done on a at surface.

Wipe off any excess grease you nd on the screws with a napkin or an old towel. Screws
are generally greased in order to prevent rusting during production. Cleaning off excess
grease will keep your hands and printer clean during assembly.

Ditto is a rigid and robust 3D printer once assembled, however during the assembly process,
extra care needs to be taken to make sure delicate parts require more precision than force to
come together. If during the assembly process, you are unsure of the instructions, please
contact us for support. Remember, unless instructed, no part in the assembly process should
you need to exert a high amount of force to t pieces together.

Before starting calibration, ensure that all screws and pulley setscrews are properly tightened.
Common calibration issues such as skipping and backlash are usually caused by loose pulleys
and unsecured components.

Gently insert the Z-Axis smooth rods through the bottom Z-Constraint, linear
bearing of the Z-Axis bed and nally the top Z-Constraint. If you feel there is any

amount of resistance once you reach the linear bearings within the z-axis arms, do
not force it in. Pull the rod backwards gently and retry. Rotating the rod gently
while inserting may help it slide in more easily. Take your time with the bearing,
forcing the rod in will cause the bearing balls to dislodge.

* Front panel has been hidden to show gantry*

Using the previous slider assembly pictures as a reference. Insert the Front and Back slider assembly into the frame.
One way to do this would be to skewer the items on one by one as you insert the rods from one end.

For example, to insert the back rod from the right side of the frame, the order would be:

Right Inner Bearing Cap > Small Pulley > Back Slider > Large Pulley > Looped Belt > Left Inner Bearing Cap

To insert the front rod from the right side of the frame, the order would be:

Right Inner Bearing Cap > Small Pulley > Back Slider > Small Pulley > Left Inner Bearing Cap

Make sure to note the orientations of the inner bearing caps, and directions of the pulleys.

Y-Axis Rod (255mm)

* Side panel has been hidden to show gantry*

Similar to the Front and Back rod assembly, installing the Left and Rod right will require you to insert the rod from
one end while inserting the parts in order. Here is the tricky part: While skewering the pulleys onto the left and right
rods, you will also need to skewer the belts from the front and back sliders.

To insert the left rod from the front side of the frame, the order would be:

Front Inner Bearing Cap > Small Pulley > Back Slider > Small Pulley > Back Inner Bearing Cap

To insert the right rod from the front side of the frame, the order would be:

Front Inner Bearing Cap > Small Pulley > Back Slider > Large Pulley > Looped Belt > Back Inner Bearing Cap

Once the Left and Right rods are installed, you will need to pop the Front and Back rods back out slightly to loop
the belts onto the pulleys. Once the belts are seated onto the pulley, you will need to use a bit of force to insert the
rods into the bearing.

After installed the the gantry, all the belts (except for the closed loop belts) should be looping across a pulley on
each end.

The frame has been hidden to give you a clearer view. To insert the cross rods, one by one take the rods and
insert it into one end of the slider. Push the rod into the rst slider to give you enough room to bring the rod up
into the gantry so it becomes leveled with the second slider. Then retract the rod so it can be inserted into the
second slider.

For Pre-Assembled Carriage:
Position the carriage in the right direction (Arrow on assembly pointing toward back of printer), take any of the
two rods and insert it carefully into the respectively linear bearing. Bring the rod and carriage into the gantry
space, and insert one end of the rod into the slider, twist the rod while supporting the slider will help you move
the rods easier. Once you have enough clearance to insert the other of the rod into the slider, twist the rod again
to insert into the slider on the opposite side. Repeat with second rod.

Take extra care when inserting the smooth
rod into the linear bearing. Go at it slowly
and make sure to not force the rod into
the bearing to prevent the ball bearings
from dislodging.

the slot on the frame, insert a M4 nut into
the T-slot.

2. Look the belt around the pulley and seat
the motor into the slot. You may need to
shift the motor foward or backward within
the bracket to make sure the belt is
tensioned and does not have extra slack.
Tighten the screws once the motor is in the
correct position.

4. Position the pulley so the belt is perpen­dicular and not angled in a way that the
belt is rubbing against hte pulley or the

belt is properly tensioned to avoid giving
the belt any slack.

3. Tighten the setscrew within the pulley on
the at edge of the motor shaft to secure
the pulley.

4. As shown in Step 4, take a minute to
ensure that all belt are properly aligned.
Belt should always sit perpendicular to the
pulley and should not be angled in any
way. Also make sure the the belt teeth is
fully seated into the grooves of the pulley
and not chewing into the walls of the
pulley. You may need to loosen the sets
screws on the pulley to re-adjust the
positions.

5. Connect the 4-pin motor wire to the port
located on the bottom edge of the motor.

setscew very slowly as the glass on the
thermistor will crack if there is too much
pressure applied. There just needs to be
enough force applied so the thermistor
does not slide out of its slot.

On the back face of the hotend, there will be two slots. The large of the two slot will be for the heater cartridge,
and the smaller one is designated for the thermistor. Insert the heater cartridge and therminstor into their respec­tive slots and secure them in place using the setscrews located on the sides of the hotend. Once the thermistor
and heater cartridge are in place, route the wire into the wire guide shown in the picture.

That’s it! You have just nished assembling your very own Litto 3D printer. However there are just a few things to
check before you power-up the printer for the very rst time:

1. Make sure all screws and components are properly screwed down and secured.

2. While manually moving the the gantry system (extruder, belts, pulley, smooth rods, bearings), all components
should operate smoothly and not interferre with one another. Check that all sets screws on the pulley are
tightened, and all belts are aligned so they are seating fully in the teeths of the pulley.

3. All electronics are properly plugged in and seated into their correct ports. Make sure there are no exposed
wires in contact with electronic components, and the electronic cooling fan is properly mounted and directing
airow to the Pololu driver.

4. Make sure there is no foreign objects along the path of moving components. Avoid using lubricant on the
linear bearing (Z Axis + Carriage). Most lubricants (especially ones that contain propellants) might absorb dirt
and become more viscous over time, which can cause more friction and cause damage to the bearings.

Preliminary Run-Through

Stage 1

1. Plug in the printer. Do not turn on the printer yet.

2. Connect the USB from the printer to the USB port on your computer. If you have an LCD/SD card unit,
connect it to your printer.

3. Test the X-Axis endstop. Manually move the carriage by hand and push it to the left side of the printer and
check to see if the slider will trigger the endstop. You will hear a click when enstop is trigger. Repeat the test
with the Y-Axis Endstop. If the endstop does not trigger, you will need to re-adjust the position of the endstop
so it makes contact with the trigger pieces on the slider.

4. Tighten the thumb screws underneath the print bed springs. This will tension the springs and prevent the
bed from moving around during printing.

5. Test the Z-axis endstop. Manually turn the lead screw to bring the bed upward. As the bed approaches the
nozzel, adjust the Z-axis trigger screw located on the back corner of the printer bed so that it makes contact
with the endstop leaver before the nozzle touches the surface of the bed. The ideal distance between the
nozzle and print surface should roughly be the thickness of a piece of paper.

6. Calibrate the print bed. Using the 3-point leveling system, manually move the hotend to the each of the four
corners on the print bed. At each of the four point, adjust the thumb screws so the bed is evely leveled on all
sides.

Stage 2

1. Turn on the printer.

2. Check that both LED light strip are lit.

3. Check that the hot-end cooling fans are on and directing airow to the hot-end within the carriage unit.

4. Check that the electronics cooling fans are on and directing airow to the Arudino board + Pololu drivers.

5. Check that the print bed cooling fan isn’t on. The fan for the print bed should only activate during printing.

6. If the LED or fan do not turn on, turn off the printer and disconnect the power source. Check your wiring to
see if all wire are properly seated and secured in their sockets.

Stage 3

1. Using Coordia (Control Software) or the T.I.M Controller, connnect to the printer and test move each axis.

2. Home all axis. If the printer triggers the any of the endstop but doesn’t stop, shut off the printer immediately.
Check the enstop pin connector to see if the pins are fully seated into the housing, then make sure the housing
are properly connected to the pins on the electronics board. Since the X and Z axis endstop are grouped
together, there might be a chance that you have them plugged in reversed.

3. Using Coordia or T.I.M, set the preheat temperature for PLA (180c). Monitor the temperature level and check
that the heater cartriged and thermistor is working properly. If the hotend does not heat up, check that the
heater cartrige and thermistor is plugged in correctly. Do not touch hotend with your nger to check the
temperature as the cartridge can be functioniing correctly while the thermistor is providing a false reading.

4. Your printer is ready to start printing. Follow the calibration guide to start printing your rst object!
