IMPORTANT SAFETY INSTRUCTIONS

!

WARNING

!

WARNING

SHARP EDGES

Use caution during assembly and operation of the 3D printer to ensure no sharp edges will cut you.

Inspect the printer for any damage prior to use.

!

WARNING

FIRE

Use caution to minimize risk of fire.

Always operate the printer a safe distance away from flammable items. Use in well-ventilated areas.

DO NOT place a storage cover on the unit during operation. Only place a cover on the printer after it has thoroughly cooled down.

!

WARNING

HOT SURFACE

Motor surfaces become hot during operation.

Hotend and heater cartridge become hot during operation.

DO NOT touch hot surfaces, because they can cause severe burns.

Allow the hotend to cool before touching it without proper tools.

!

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 sufficient electrical supply for supporting the requirements of the motor.

!

WARNING

3

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.

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 find anything missing, please contact us via e-mail at [email protected]

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 flat surface.

Wipe off any excess grease you find 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 fit 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.

Z-Axis Rods (350mm x2)

Gently insert the Z-Axis smooth rods through the bottom Z-Constraint, linear bearing of the Z-Axis bed and finally 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.

12. Left + Right Slider

TINKERINE STUDIO

Y-Axis Rod (314mm)

* 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.

Install the outer bearing caps to cover the exposed bearing and prevent the rods from sliding out. If you have oriented the inner bearing caps correctly in the previous steps, it will align with the outer bearing caps. If not, you need need to flip the inner bearing cap.

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 first 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.

B. Before inserting the motor bracket into the slot on the frame, insert a M4 nut into the T-slot.

C. 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.

D. Position the pulley so the belt is perpendicular and not angled in a way so that the belt is rubbing against the pulley or the wooden frame. Tighten the set screw of the pulley on the flat edge of the motor shaft once you have positioned the pulley.

E. Insert the M4 screw from the bottom and secure the motor bracket to the frame.

Insert the motor wedge to tuck it under the other side of the motor.

B. Insert the M3 screws to secure the motor to the frame. Make sure to position the motor on the frame at a point where the belt is properly tensioned to avoid giving the belt any slack.

C. Tighten the setscrew within the pulley on the flat edge of the motor shaft to secure the pulley.

D. 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. Check all belts.

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

Place the bottom portion of the extruder onto the carriage and insert the hotend + hotend mount into the center of the carriage through the slot located on the back on the carriage.

With the two M3x20 screws, secure the extruder and hotend to the top plate of the carriage. The screws should thread into the hotend mount, securing all the components together.

Ensure that the acrylic spacer is attached to the top of the hotend and leave the ceramic insulation wrapping attached to the hotend.

Your printer’s hotend may already have the heater cartridge and thermistor already installed into the hotend. In this case you will just need to route the wires as shown.

!

Take extra care when tightening the setscrew for the thermistor. Turn the 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.

Heater Cartridge

Themistor

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 wires into the wire guide shown in the picture (blue path).

To install the print bed fan, grab a fan and point the sticker side downward. Orientate the fan so the wire is pointing toward the back of the printer, doing so will give you cleaner look when you are performing wire management. Similar to the wires for the hotend, route the fan wire up the wire guide.

It is recommended that you mark the ends of the wire so you are able to distinguish the separate fans during the wire connection process.

Insert the M3 screw through the bottom of the air duct and fan, there are two mounting holes on the bottom of carriage. The mouth of the fan duct should be point toward the

To install the hotend cooling fan, grab the fan and point the sticker side toward the hotend. The fan should sit between the two carriage plates so if it does not fit, you will need to loosen the carriage screws. Route the fan wires so that it comes out of the top right corner and sits in front of the fan and wire guide. Secure the fan to the carriage with screw 1 and attach the fan guard to the with screw 2 + M3 Nut.

1. Route the wires from the Left Side LED,

X+Y+Z-Axis Endstop, X+Y Motor wire through the wire holes from the front side of the machine to the back. Route the wire so it runs behind the Y-Axis motor and underneath the X-Axis motor. Run all wires through the hole located on the back corner of the motor bracket.

X-Axis Endstop Wire

Z-Axis Endstop Wire

2. Gather all the wires from the carriage fan, heater cartrige, thermister, Right Side

LED, and extruder and route the wires through the hole located on the motor bracket.

3. You may choose to label the wires with masking tape before you route them through the hole located on the bottom right corner of the printer. This will help you indentify the wires later on.

NOTE 1: For the wires coming from the extruder units, make sure to leave enough slack so the wires still have some slack once the extruder moves to it’s homing location (Front left corner).

NOTE 2:

Once the wires are all routed and connected to the electronics, use the supplied wire sleeve to clean up the exposed wires on the back and top of the machine. Use the larger sleeve for the back portion of the machine and the smaller wire sleeve to wrap the wires coming from the extruder.

NOTE 3

After you have finished sleeving all the wires and have confirmed that all electronic components are in working order. Use the supplied zip-ties to secure the ends of the wire sleeve.

That’s it! You have just finished assembling your very own Ditto 3D printer. However there are just a few things to check before you power-up the printer for the very first 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 teeth 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 airflow to the A4988 Stepper 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 lever 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 airflow to the hot-end within the carriage unit.

4. Check that the electronics cooling fans are on and directing airflow to the Arudino + A4988 Stepper 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 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 finger 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 first object!
