Before start printing, you just need to confirm that your machine is correctly configured and with
the latest firmware.

11

EXTRUDER CALIBRATION

One very important step before you start printing is to ensure that the extruder is correctly aligned.
In some cases, extra paint is present in the metal mainframe that causes a misalignment after
assembling the extruder.
Because of this, you can have a extruder like the following example.

If this happens, just follow the next steps to correct this.
Use the four M3 plain washers, as referred to on page C7 of the Assembly Manual, to give a little
distance between the extruder heat sink and the metal frame.
This is represented in the picture.

12

Use one plain washer on each of the cylinder-head screw M3X30.
After you place the four washers, the extruder should be aligned.

13

BED CALIBRATION

Before your first print, you must calibrate the bed so the first layer of the print can adhere to the
bed evenly, otherwise it may ruin your print.
For this you can use the LCD. Just follow the next steps:

On the LCD, push the button to access “info screen”.

In “info screen” select “Prepare”.

In “Prepare” go to “Move axis” and select the axis you want to move (X, Y or Z).

Select “Move 1mm.

Rotate the button to the right or to the left to make the axis move.

14

Now, you use the 3 screws to level the bed. Remember that you need to keep the same clearance
from the nozzle on all points of the bed.

Next step is to adjust the home Z axis so the nozzle can stay at a distance of about 0.2mm from the bed.
You can use a sheet of paper as reference for the needed distance.

Example of the nozzle staying at about 0.2mm from the bed:

Make sure the clearance between the nozzle and the build plate is the same near the three
calibration screws. If you find that the calibration is not satisfactory, repeat the process and check
the clearance on all three points again.

15

This option in the LCD will help you to ensure
that prints will adhere to the bed, even if the bed
is not perfectly level. Before this, make sure the
bed is calibrated. Now follow these steps to en­able the “Level bed” option. In the “Info screen”
select “Level bed”.

The machine will now home the axis, you need
to press twice to advance to the first calibration
point.

The X carriage will move to this point
(point 0,0 - origin).

This image is what will appear at the LCD after
you select “Level bed”.

Rotate to adjust the height of the extruder and
push it to select the value.

Note: You must make an adjustment at each point, even if a point

doesn’t need to be adjusted. Just press the button to accept

SEMI-AUTOMATIC 9-POINT CALIBRATION

16

On each of the nine points, you must adjust the extruder height to make sure that the table
and the extruder have a clearance of more or less 0.2mm.

You can see this points represented on the next picture.

Your printer should make a sound after finishing the leveling, if doesn’t beep at the end of the
calibration you need to manually save the settings by goint to “Control” select “Store memory.

17

LOAD/UNLOAD FILAMENT

This option in the LCD will help you to load and
unload filament in an easy way.
For this you just need to follow the next steps.
In the “Info screen” select “Change filament”.

Now it is recommended that you select “Move to position” to ensure that the extruder goes to
a safe position to change the filament.
After this you come back to this menu and select
the extruder you want to change the filament,
Extruder 0 or Extruder 1.

Select which material you are using, use ABS for
Nylon, PETG and TPU.

Select which option you desire, “Load or Unload”
the filament.

The selected extruder will heat up;
When the extruder reaches the correct temperature, the printer will make
a noise, you need to press and hold the button to continue, then the printer
will perform the movement, Load or Unload and go back to the menu once
finished.

18

USING AN SDCARD

After we correctly configure Cura 15.04.6, we just need to import the STL file and export the Gcode.

We export the Gcode by doing “Save toolpath” and choosing to save it in your SDcard.
Now insert the SDcard into the printer and with the LCD button, navigate to “Print from SD” and
choose the file. Your printer will start heating and will then print the object.

19

GETTING STARTED
WITH DUAL EXTRUSION

Before you start printing with dual extruders, you need to setup the offset of the extruders.

HOW TO SET EXTRUDER OFFSET

Download and drag the following file into Cura workspace:

https://github.com/beeverycreative/helloBEEprusa-software/raw/master/dual_extruder_offset.amf

20

Export the G-Code and print.
Grab a metric ruler and measure the distance
of any axis offset in the 3D printed object.

(E.g.: The red rectangle and the blue rectangle
should coincide. If not, measure the offset between them as
precisely as possible).

Now you need to setup the offset in Cura.
Go to Machine > Machine Settings,
under Extruder 2 change the Offset X
and the Offset Y to the number that
was measured before - in this example,
offset of 2.53mm for X and 0 for Y.

Test the offset and repeat the process if the print
does not look good. On the right, an example of a
printed object with a good offset setup.

2,53mm

21

HOW TO SET THE TWO EXTRUDERS AT THE SAME HEIGHT

Ensure that the X carriage has the exact same height, using its Z-axis motor as a reference, and
ensure that the bed is calibrated, with the lowest nozzle as reference.

22

With the extruders on the center of the print bed and with
the lowest nozzle touching the table, take off the printed
part containing a fan. Remove the one pertaining to the extruder
that isn’t touching the table.

Unscrew the little screw and we can now lower the nozzle until it is touching the table too.

Screw it again and assemble the blower, now we have the nozzles at the same height.

23

STEPS TO PRINT WITH TWO EXTRUDERS

1. Load the two STL files in to the Cura, for instance these 3DBenchy files.
The first loaded STL file will be printed on extruder 0 and the second one on extruder 1.

2. Select any object and with mouse right click, select the “Dual extrusion merge”.

3. After the merge, the model will have 2 different colours.
The yellow part will be printed by extruder 0 and the red part by the extruder 1.

4. Now export the G-Code and it’s ready to print.

24

PRONTERFACE - BED CALIBRATION

Before starting to level the bed, you can jog the extruder and the bed
using the jog buttons (picture below) on Pronterface.
You can move the Z axis in a way that the nozzle stays a bit closer
to the bed and is essential for the following steps.

Use the 3 screws to level the bed as shown in the previous topic “Bed calibration using the LCD”p.13.

PRONTERFACE - FIRST PRINT
You can load/unload filament using
the Pronterface control panel:

To load, first you need to Set the extruder
heating temperature and wait for
the temperature to reach that value.
You can look at the graph to verify.
When the extruder reaches the temperature,
then you can click on the Extrude and then
you can insert the filament on the extruder.
To unload, you also need to set the same
extruder heating temperature.
Afterwards, just click the Reverse and gently
pull the filament from the extruder.

You can change the extruder by clicking on the button next to “Tool”, Tool 0 is for the first extruder
and Tool 1 is for the second extruder.

29

First configure Pronterface and Cura, after that, use Cura to generate the GCode of the object you
want to print.
Connect the printer via USB.

Click on the “Connect” button and the printer will be connect to Pronterface, after that click on the
“Load file” button and select the Gcode file that was generated by Cura before.
Now click on “Print”, the printer will start to heat up and will print after that
Remember to never disconnect the USB cable or close the Pronterface, the printer will stop
if you do that.

LOAD/UNLOAD FILAMENT (OPTIONAL WAYS)

You can follow these steps to load and unload using the LCD:
In the LCD push the button to have access to the “info screen”.

In “info screen” select “Prepare”.

In “Prepare” go to “Preheat PLA” or “Preheat ABS”.

30

In “Preheat PLA” select “Preheat PLA 0”, the printing table and the extruder 0 will start heating or
select “Preheat PLA 1”, the printing table and the extruder 1 will start heating.

After finishing heating, push the button to go to the “info screen” and select “Prepare”.

In “Prepare” go to “Move axis” and select “Extruder 0” or “Extruder 1.

Select “Move 1mm”.

In this screen you rotate the button to the right if you want to load and to the left if you want to unload.
