1. INTRODUCTION
Congratulations on your purchase of the CraftBot 3D printer and welcome to the word of 3D crafting!
At CraftUnique we believe that 3D printing opens a new window to enhance creativity. It oers
outstanding crafting experience even without prior programming or 3D printing experience.
How does the printer work? The CraftBot 3D printer makes solid, three-dimensional objects out of
melted plastic lament. Design Your objects with the help of a 3D design program. Then use the
CraftWare program (downloadable from www.craftunique.com/craftware) to transform Your 3D
design les into printing instructions for the CraftBot 3D printer. Transfer this to Your CraftBot 3D
printer via USB drive or USB cable. The CraftBot 3D printer will melt plastic laments and squeeze it
out onto the building plate in thin lines to print your object layer by layer.

you are printing with. On the main menu press the thermometer icon.
At this point you will see a new menu indicating both Head temps” plus the “Bed temp”.
Select the Extruder icon and the Bed icon (line with 3 wavy lines above) to commence the
heating process. Once the extruder reaches the target temperature of your lament (keeping in mind
that dierent materials such as PLA, ABS, and PET have dierent temperature settings), you can start
printing.
5.2. LOADING THE FILAMENT
1. Heat up the printer.
2. Remove the lament guide tube from the insert hole on top of the extruder.

12
CraftBot 3
3. Cut the end of the lament free from any kinks and bad ends. Insert the lament from the spool into
the bottom hole of the lament FMS encoder. Please make sure that the lament spool feeds directly
into the FMS encoder from the bottom so that the lament keeps itself straight on course and free
from any snagging. This way you will avoid any unnecessary bending of the lament and any wrong
diagnostics from the lament monitoring system.
4. Enter into the extruder menu. Push the lament into the extruder hole, against the drive gear.
5. Press the bottom icon for the extruder you are about to use now using or load lament button
on the screen. The load button will extrude 15 cm of lament automatically, this can be interrupted
by pressing the back button at any time.
6. You can also use the “extrude” menu on the touchscreen to extrude lament in /out of the
nozzle manually. Re-insert the lament guide tube back into the hole at the top of the extruder. The
two heads and the build platform can now be set individually.
5.3. REMOVING THE FILAMENT FROM THE EXTRUDER
Never remove the lament from the extruder if the extruder is cold! Always preheat the extruder before
removing or changing laments. Removing the lament from a cold extruder might damage it! You
don’t have to remove the lament between prints.
1. Heat up the extruder rst to the correct temp for that lament type.
2. Press the Load rst for 1 or 2 seconds and then press the button. This will automatically
extrude a small amount of lament to prevent clogging and switch into reverse until lament
removed from the extruder head.
3. Once the gears have begun to retract the lament you will be free to pull it out from the printer back
to the spool ready to load a new lament.
5.4. CALIBRATION SETTINGS
5.4.1. LEVELING THE BUILD PLATE
CraftBot has a leveling procedure which ensures that the extruder and the heated build plate are at optimal
distance and they must be leveled evenly. Smaller gap or uneven levelling may lead to the damaging of the
Kapton cover sheet on the build plate or the extruder itself.
After calibrating the build plate the Z-calibration is recommended.

13
CraftBot 3
Calibration process:
1. Heat up the heads and remove the laments. It’s easier without lament.
2. Select the Settings menu on the LCD screen go to. page 1 select the Leveling icon (three crossed
circles which represent the three knobs and screw) .
3. Follow the step-by-step instructions on the LCD screen:
• It is recommended to turn all three black knobs holding the build plate, all the way to the right until
the springs in between have been compressed fully and the knobs begin to feel tight. (Under the
heater plate There is one knob at the front in the middle and two in the back left and right corners
of the build plate). Do not force them!
• Locate the 0.35mm spacer card that are located in the Nozzle kit boxes among the other accessories
that came with the printer. This card will ensure the optimal distance between the build plate and
the extruder nozzle. Please keep this card for future use.
• The preprogrammed leveling process will rst set the front center point. Press the right arrow to
continue. wait for the nozzle to get to the correct point on the build plate. Place the spacer card
above the front center black knob on the build plate, Adjust the front center knob if needed, based
on the instruction on the screen.

14
CraftBot 3
4. Repeat the process with the two back knobs. First the right back, then the left back knob will be
adjusted.
5. Before switching from knob to knob, please remove the leveling card. When the nozzle is in the
correct location replace the card as necessary for further testing at that location point.
6. Process is to be repeated twice to make sure that all 3 knobs are in the correct position.
7. As a result, the building plate should be evenly calibrated.
8. You can return to the main menu by pressing the right arrow.
5.4.2. DUAL HEAD CALIBRATION (Z)
The Z axis must be calibrated so that the two heads are at the same height and are at the same distance
from the build platform. If there is a height variation between the two heads, it will be visible on the
printed object.
Calibration process:
1. Heat up the heads and remove the laments!
2. Select the Settings menu on the LCD screen and go to the 5th. page using the right arrow. Select
the Z calibration icon . 2 printheads icon.)
3. The calibration must be initiated
4. select the 2 arrow icon

15
CraftBot 3
5. When the rst head has moved to the reference point which will be at the front screw point, the build
platform and the nozzle tip must be set perfectly to each other with the nozzle JUST touching the
surface of the build platform. with no space between nozzle and bed.
6. Then, press the change heads button in the middle.
7. The First head will move back to the home position and the second head will move to the same
reference point at the front of the build platform.
8. loosen the two screws on the left side of the Black heatsink. Drop the nozzle to the bed and tighten
the screws.
9. Repeat this twice to make sure that both heads 1 and 2 are at the correct same Z height position.
If you have moved the build plate leveling screws please go back to redo a bed leveling.

16
CraftBot 3
5.4.3. DUAL HEAD CALIBRATION (X-Y)
The X-Y axis must be calibrated so that the coordinate system of the two heads is completely aligned. So,
if we send both heads to the same coordinates then they should be at the same point. This is important
when we are printing an object with both heads. If there is any deviation, the print will be misaligned;
for example, if there is a gap between two materials or if the two materials are printed onto each other.
Calibration can be performed on the X and Y Axes individually, or on both axes at the same time in an
automated program by using centre XY button.
Calibration process:
1. Heat up the heads and load the laments into both extruders!
2. Select the Settings menu on the LCD screen and go to the 5th page. Select the calibration icon
(to the oset coordinate systems)
3. Head and bed temperature must be entered (what material is placed into the extruder head: ABS-
PLA-PET)
4. Start the calibration of the X, Y, or the automated XY axes
5. The printer will print the calibration lines with both printheads. It will print the number 1 next to the
rst line.
6. The user must determine which of the lines printed by the two heads is aligned fully.
This head’s number must then be chosen from the display after the printing. In the case of the
simultaneous calibration of both axes, the matching lines must be given rst for the X, then for the
Y axis.
7. To make sure it is calibrated and the 16th lines are aligned.
8. When your lines are Not aligned at the 16th lines:
• Chose the head’s number in the LCD screen, and wait for the text message. If you see the red
message, the calibrate is not correct so you need to start a new XY calibration with the new rate.

17
CraftBot 3
9. When your lines aligned in the 15th, 16th or 17th lines:
• Chose the head’s number in the LCD screen, and wait for the text message. If you see the yellow
congratulation message, the calibration is correct and you can exit to the main menu.
10. When you have completed the calibration the rst time An extra second or third calibration is always
recommended to get the perfect settings.
5.4.4. FMS OPERATION
The lament monitoring system observes the lament ow during printing. If the printer detects a jam
during printing, it will try to resolve it on its own. If it is unable to resolve the jam, then an error message
will appear on the display, the message will appear in the application, and the printer will also send an
email message. Please note, the wi should be set up correctly rst.
