IDEX USER MANUAL V1.0
1. INTRODUCTION
Congratulations on your purchase of the CraBot Flow Generation printer and welcome to the world of 3D craing!
At CraUnique we believe that 3D printing opens a new window to enhance creativity. It offers outstanding craing
experience even without prior programming or 3D printing experience.
How does the printer work? The CraBot 3D printer makes solid, three-dimensional objects out of melted plastic
filament. First you will have to have your objects with the help of a 3D design program. Then you will need to use
the CraWare program (downloadable from www.craunique.com/craware) to transform your 3D design files into
printing instructions for the CraBot 3D printer. Transfer your files to Your CraBot 3D printer via USB drive or Wi-Fi.
The CraBot 3D printer will melt plastic filaments and squeeze it out onto the building plate in thin lines to print your
object layer by layer.

In the Heating menu you can switch on or off the heating by touching the element (head, build plate) icons.
Allowed temperatures:
• Head temperature: 40-300 °C
• Build plate temperature range: 40-110 °C
5.3. Loading the filament
Heat up the extruder where you want to insert the filament.
• Take the end of the filament out of the securing hole on the Filament spool.
• Cut and the end of the filament so the filament is straight and has no damages bends kinks or melted parts.
• Remove the filament guide tube from the insert hole on the top of the extruder.
• Insert the end of the filament from the spool UP into the filament guide tube holder, then into the filament guide
tube. Pass the filament through the tube until it protrudes on the extruder side of the tube.
• Push the filament into the top of extruder hole.
www.craftbot.com
IDEX USER MANUAL V1.0
Select the Extrude menu on the Home screen.
Before extruding, make sure the head is next to the build plate, not pressed into the plate or directly above.
• To extrude filament from the print head, use the down arrow on the touch screen.
• Press and hold the buon to keep the filament extruded of the head.
• Automatic filament feed can also be performed by pressing the Load buon on the boom bar.
By pressing the buon once, the head automatically extrude some filament.
• Filament loading is successful when the melted filament flows out of nozzle evenly and vertically.
Watch out! The freshly spilled molten filament is hot. Avoid contact with spilled filaments or other flammable
materials in the near.
5.4. Unloading the filament
Never remove the filament from the extruder if the extruder is cold!
Always preheat the extruder before removing or changing filaments. Removing the filament from a cold extruder
might damage it!
You don’t have to remove the filament between prints.
• Heat the extruder as described above.
• Make sure the head is next to the build plate, not pressed into the plate or directly above.
• When the extruder reaches the temperature required for the filament, press the down arrow ,
then the up arrow.
• Automatic filament unload can also be performed by pressing the Unload buon.
• When the gears start to retract the filament, you can safely pull out the rest of the filament from the guide tube
and connect the end of the filament to the spool for safe keeping. Now you are ready to load a new filament.
5.5. Changing filaments
• When changing filaments, note that different filaments, such as PLA, ABS, and PET, have different temperature
characteristics.
• If you want to replace a material with a higher temperature (eg. ABS, PETG) with a material with a lower
temperature (PLA), it is need to heat the head to a higher temperature so that the previous material can leave the
head completely before the other filament in its place.
• When changing colors, always push more material out of the head, ensuring that the replaced color is completely
removed from the head. During printing, it may be uncomfortable to notice that the print color is still blending
with the previous color, for example, changing from red filament to white.

IDEX USER MANUAL V1.0
5.6. Start a print
You can print the previously saved .gcode files in more ways: Either form the printer 4GB internal storage, or from USB
flash drive. Save the gcode file created by the CraWare slicer program onto USB flash drive or to the printer internal
storage directly. See section 7.
• Select the Print menu on the main screen.
• Please locate the file what you like to print. The
files on the flash drive can be located under the
“pendrive” folder, the internal storage is under the
“local” folder.
• Move the list up or down to locate the gcode of the
item you want to print and select it. You can only
select one gcode for printing, if multiple items are
selected, printing cannot be started!
• Press the Start buon in the right corner of the
screen.
• The machine warms the print head and the build
plate to the values specified in gcode.
• Printing starts when the machine reaches the required operating temperature.
• Please make sure that you have enough filament for the selected project. The quantity is pre-calculated by
CraWare.
• Aer the object has been printed, remove the build plate. Printed object can be removed easily, just bend the
flexible build plate. Please note, if the object is still warm, it may bend when removed. To avoid this, please allow
some time to cool.
5.7. In-print adjustments / pause menu
During printing, sometimes it can be essential to modify the printing parameters on the fly.
Also this menu pops up, when the printer gets a pause command from the gcode or from the screen.
In Pause menu users can change filament, continue printing or terminate the printing operation. Pressing the resume
buon will continue the printing. For filament change use the Extrude / Reverse functions, or the preprogrammed
Load / Unload options.
The in-print adjustments overrule the seing is the gcode.
You can change the print seings during printing by

5.9. Calibration
You need to calibrate your printer periodically to ensure that you always print in good quality, and good adhesion to
the build plate. There are a total of 4 calibration processes that ensure perfect print quality.
There are a few important rules to follow before calibrating:
! Heat up the nozzle and remove the filament from the extruder.
! Clean the plate and the nozzle tip.
! Make sure the metal plate is pushed back as far as it will go.
To preform the calibration, please follow the next steps:
• Select the Seings menu on the LCD screen and touch the Calibrate icon
• Select which calibration process you want to perform
• Press Start
5.9.1. Assisted bed calibration
Adjusts the parallelism between the build plate and XY mechanics, and the distance between the nozzle and the
build plate.
The assisted bed calibration requires you to manually adjust the build plate. It will be adjusted using the 3 knob
screws at the boom of the build plate. There is one knob at the front in the middle and two in the back le and right
corners of the build plate.
At the beginning of the process, the printer measures the distance between the build plate and the nozzle tip using
the BL-Touch sensor. If the distance or parallelism is not optimal, the calibration will begin.
The print head begins to measure at the front in the middle point. At the boom of the screen, you can see the scale
of the deviation.
If the deviation is large, the markings are dense. The
arrows below the markings indicate which direction the
knob should be twisted to achieve optimum adjustment.
To achieve optimum value, the meter should be wrapped
between two prominent lines.
If the measurement is correct, the Next buon appears. By pressing the buon the printer proceed to the next
measuring point. Once all three measurement points have been completed, the printer will re-check the distances.
If all is well, the measurement process is complete.
5.9.2. Mesh bed leveling
Creates a map of the build plate and compensates for any surface inequalities while printing the first few layers.
For this calibration, no user intervention required.
During the process, the printer measures the build plate at 3 different temperatures: 60°C, 80°C, 100°C
This process takes 15 minutes to complete.
www.craftbot.com
IDEX USER MANUAL V1.0
5.9.3. Extruder (FMS) calibration
This calibration is measuring the Filament Monitoring System (FMS) sensor values, and adjusting it, if necessary.
For this calibration, no user intervention required.
Please make sure that filament is loaded into the head you want to calibrate, before starting the process.
5.9.4. Offset calibration
The offset calibration requires manual adjustment on the printer.
Please prepare the 2.5mm hex wrench supplied with your printer.
This calibration process calibrates the following parameters:
Z limit distance: Required for resume printing function.
BL-Touch - nozzle offset: Required for the assisted bed and mesh bed leveling.
Extruder 1 and Extruder 2 X-Y offsets: Required for dual mode prints.
Extruder Z offset: Required for dual mode prints, to the heads be on the same Z level.
This adjustment is requires user intervention:
• The build plate moves downward and moves the right head over the build plate and stops.
• Loosen the two screws on the le side of the heat-sink through the gap between the fan grilles and allow
the nozzle to move down. If necessary, please press down the heat block with the hex wrench.
• Press the Next buon. The build plate pressing up the loosen Extruder 2 to the proper height.
• Tighten both screws and press Next to continue calibration.
If the alignment is proper, the calibration process will continue, with no intervention required.
5.10. Removing objects from the build plate
The Crabot FLOW printer are equipped with removable flexible build plate. Removing printed items from the build
plate is easier than ever.
Please follow the steps:
• Remove the build plate from the printer.
• Allow the build plate to cool down to room temperature.
• Bend the build plate as seen on the picture.
Please note, if the object is still warm, it may bend when removed.
Please do not over-bend the build plate! It may damage it permanently.

IDEX USER MANUAL V1.0
5.11. Printing modes
There are a total of 6 printing modes available to help you get the most from your printer.
To adjust the print mode, select the Seings menu on the LCD screen and touch the Mode icon.
Default mode: Gcode will determine whether the printer operates with one or two print-heads.
Mirrored printing: If an object fits on half of the build platform, then there is the option of printing two objects at once
which will be mirror images of one another. This way, two objects can be made in time it takes to print one object. For
example, if printing a hand, the printer can make a right and a le hand at the same time. If a symmetrical object is
being created (a heart, for example), both halves can be printed at once and the entire object can be prepared in the
time it takes to print half an object.
Parallel printing: If an object fits on half of the build platform, there is the option of printing two objects at once that
will be completely identical. This way, two objects can be made in time it takes to print one object. The printer’s productivity is therefore doubled.
Support printing: If a model has been sliced for a single head printer and it contains supports, then the printer will
recognize the supports automatically and will print them with the second head. With this mode you can print
supports with soluble material without re-slicing the model.
Inverted head: It swaps the 2 heads while printing. A part what should be printed with the first head it will be printed
with the second head and vice versa. You do not have to replace the two filaments at the beginning of the print if they
are swapped in the two heads.
Backup: It can be used when you print with 1 head. While printing, if the first head jams or runs out of filament, the
second head will continue automatically thus the print won’t stop. When using this mode it is recommended to use
the same material type (or at least the same color) in both heads so there won’t be any difference on the final printed
model.
5.12. Firmware update
CraBot FLOW printers are able to update itself through Internet or from flash drive. We are continuously improving
the features of our printers for the best user experience.
If the printer is connected to the Internet, and the update reminder function is enabled, the printer warns you, when a
new firmware is available.
If the printer is connected to the Internet, but the update reminder function is disabled, the printer need to be updated from the Update menu.
If the printer is not connected to the Internet, you may have to download the latest firmware from our website
(hps://crabot.com/firmware), and copy it to the root folder of a flash drive, without unpacking.
Please follow the steps:
• If you want to update from flash drive, insert the flash drive which contains the previously copied firmware file to
the printer’s USB port.
• Select the Seings menu on the LCD screen, and touch the Update icon.
• Select the source from where you want to perform the update.
Please do not interrupt the process, or unplug the printer during firmware update.
The update process takes about 3 minutes.
When the update is finished, please restart your printer.

8. CLEANING AND MAINTENANCE
IMPORTANT!
Cleaning and lubrication should only be conducted while the extruder and built plate are cold. Please allow the
CraBot 3D printer to cool down at least 30 minutes before cleaning or maintenance. It necessary to clean the
printer aer every 1000 hour. Aer every 1000 hour we need to change the used and worn parts in the printer. The
printer will warn the user.
8.1. Cleaning
Clean the metal housing of the CraBot by wiping with a damp cloth.
Cleaning the build plate with window cleaner or Acetone. Wipe clean with a dry cloth or paper towel.
www.craftbot.com
IDEX USER MANUAL V1.0
8.2. Lubricating
The CraBot printer should be lubricated at least once aer every 50 hours of use or every 6 months.
Tools needed for lubrication:
• PTFE based spray lubricant or grease
• 2 separate lint-free rags or thicker stronger paper towels
• Personal protection such as gloves and safety glasses/goggles
• Lighting to see the interior of the CraBot correctly (lamp)
1. Move the build plate and the extruder to the „Home” position.
2. Once the extruder and bed are in the home position, turn the CraBot printer off and unplug it from the
electrical outlet.
3. If you look beneath the build plate you will see three rods that run vertically in which the build platform moves up
and down on. The two outside rods are smooth and the center rod is threaded. These three rods are known as
the “Z-axis rods”.
4. Place a folded paper towel or a lint-free rag behind the center rod. This rag is used to protect other areas of the
printer from any over-spray that may occur.
5. LUBRICATE ONLY THE PARTS RECOMMENDED IN THIS MANUAL!
6. Spray the threaded Z-axis rod at a relatively close distance to reduce over-spray. Make sure the lubricant
reaches the inside of every thread (if using grease, spread with hand wearing gloves).
7. Make sure not to over-lubricate, spray only the minimum required amount!
8. Do not spray the other two rods directly! Spray the towels and wipe it onto the rods.
9. Remove the rag from the CraBot interior.
10. Plug in and power up the CraBot and move the build plate to the lowest point (go to Axes menu, and press the Z
down arrow until the bed reaches the lowest point).
11. Turn the CraBot printer off and unplug it from the electrical outlet.
12. Place a second clean rag on top of the heated build plate to protect the components and Kapton from any over-
spray.
13. Repeat the process for the top side of the Z-axis rods the same as you performed on the boom side:
protective rag behind threaded rod, spray, wipe excess lubricant on other two outside rods.
14. Power up the CraBot once again and raise the build plate back up to the highest position (set the X, Y and Z to
the home position).
15. Turn the CraBot printer off and unplug it from the electrical outlet.
16. Wipe any excess lubricant off from the boom side of the Z-axis rods.
17. Power up your CraBot once again and move the build plate back to the lowest point.
18. Turn the CraBot printer off and unplug it from the electrical outlet.
19. Wipe any excess lubricant off from the top side of the Z-axis rods.
20. Power up the CraBot once again and raise the build plate back up to the highest position.
21. Turn the CraBot printer off and unplug it from the electrical outlet. The motors will now disengage so that you
can move the extruders freely by hand.
22. Use an oiled rag to lubricate the X and Y linear rails. Do not spray from above! Move the extruders back and forth
by hand to both extremes of the axes. When the extruders move absolutely smoothly you are finished.

IDEX USER MANUAL V1.0
8.3. Removing clogging of the extruder
The number one inconvenience that you will run across when 3D printing is clogging of the extruder. But we have
good news for you! This problem can be easily avoided by following a few simple rules of “3D printing etiquee”.
• First, always wait until the extruder is fully heated ti its intended temperature before inserting the filament.
Inserting the filament at a lower temperature is just asking for a clog.
• When unloading or changing the filament: always heat up the extruder all the way first. Then “Extrude” for 5
seconds and then immediately press “Reverse” aiding the filament retrieval by pulling a lile bit on the filament
end coming out of the extruder with your fingers. The “Extrude” is necessary, because the hotend need to melt
the whole previously melted filament.
• If the extruder is clogged clean out the passageway of the extruder. You can use one of the small hex wrenches
that came with the Crabot. To do so. Heat up the extruder to 250 °C While the extruder is empty push down any
excess filament out by plunging the hex wrench down into the passageway: Make sure to do adequately but not
in a violent way which would damage the machine, and always take precautions because the extruder is very hot!
• It is especially important to clean out as much old filament leover between using different filaments, as the
different characteristics of the filaments’ properties (even printing the same material in a different color) can
cause clogs from inconsistencies. For example: you must heat up to 250°C to clear out any extra ABS before using
PLA.
Clogging is the most common problem in every 3D printer and cannot be prevented 100%, but if you follow these
simple steps you will prevent 95% of occurrences. If you still cannot clear the passage with just this method, you may
want to move onto the next method by following these next steps to actually remove the nozzle itself…
8.4. Removing the nozzle
Remove the filament from the head or cut the filament at
the point closest to the extruder.
• Remove the head only when it completely cooled to
avoid burns.
• In the Navigation menu, lower the bed level for
convenient head access during the process.
• Turn off the printer.
• The fan assembly on the head can be removed using
the 2-2 screws on the sides. The fan unit can then be
easily removed.
• Loosen the screw on the head at the boom of the
silicone cover, but do not unscrew it. Pull out the
heat cartridge and temperature sensor from the
Heat-block.
• Loosen but not remove the 2 screws on the le side
of the black Heat-sink.
• This allows the boom head to be pulled out of the
black block.
• Unscrew the nozzle and heat-break with wrenches.
• The two parts can now be cleaned comfortably with
the Cleaning Kit.

IDEX USER MANUAL V1.0
8.5. Replace the Fan set
If you have any problems from the BL touch
intermiently or not working altogether or the fans
not working, then Please follow the process below to
investigate. This could be due to pins breaking or being
miss aligned due to twisting of the Fan casing.
• On the le and the right side remove the screws with
the 2 mm Allen key.
• With one hand, hold the fan assembly steady as you
remove the last of the bolts.
• Lower the fan set about one centimeter and then
move it forward away from the Extruder.
8.6. Relocation of the Fan assembly to the extruder assembly
• Moving the fan Assembly over the extruder first
below the required height around about 1 centimeter.
Gently li the fan assembly to connect to the 2
boards together but first locate the central pin from
the Extender board into the hole of the Fan extender
board below it.
• When you have located the central hole align the
side bolt holes of the Extruder with the fan casing
holes and place an Allen key into the front bolt hole
on the right side again to keep it steady.
• Start to place the first bolt into the rear hole on the
right side. To hold the correct position taking some
of the stress off the pins.
• Place the second bolt into the front le bolt hole to
hold the fan assembly more level and upright onto
the extruder Assembly. Now Remove the Allen key, to
secure all 4 of the bolts to hold the fan set onto the
extruder assembly.
• Then you have finished the dissemble and
reassembly of the Extruder fan set from the extruder
assembly.

IDEX USER MANUAL V1.0
8.7. Applying a new Kapton sheet to your build plate
Build plate Kapton sheets get worn out in time or can be damaged by the nozzle due to incorrect levelling or
removing the printed models. Reapplying a new Kapton sheet is essential to maximize print qualities if the old one
has issues/ damages. To reapply a new Kapton sheet, take the build plate out of the machine and remove the old
sheet by striping it off of the flexible metal plate. Clean the surface of the plate with acetone.
Remove the protective plastic backing sheet (keep this safe for use later) from the new Kapton sheet. in order to get
to the sticky side. Apply some window cleaning liquid onto the plate and the sticky side of the sheet to help you to
correctly the position the sheet on the build plate. Align the Kapton to the front side of the laser marked grid. Once
the positioning is correct, squeeze out the excess liquid from between the plate and the sheet with a thin but solid
object, like a used credit card. Place the protective sheet (which was removed in the beginning) on top the new
Kapton to prevent scratches and damages during this process.
Start from the center of the plate and move horizontally and vertically. Once all the liquid has been squeezed out and
the sheet is applied properly, put the plate somewhere to dry. Allow the sticky part to rest for a day before using.
