A1.Cura for your Ultimaker
The preferred software for your Ultimaker is Cura. This
software package prepares your 3D model into instructions
that your 3D printer requires to produce an object.
Cura is developed by Ultimaker to make 3D printing as easy
and streamlined as possible. It contains everything you need
to prepare a 3D file for printing. It is fully preconfigured to
work on every Ultimaker model. Cura comes with a friendly
setup program that helps you install the latest firmware as
well as to calibrate your printer.
While you make decisions on the look and quality of your 3D
object, Cura’s slicer engine prepares your model in the background faster than ever. From there It is just seconds away
from your printer and ready to become your physical object.
With the Ultimaker 2 and Cura it’s only possible to copy your
print file to an SD card and print from it. The USB port on your
Ultimaker 2 can be used for firmware updates and in the near
future this gives a possibility for wireless printing. The USB
cable that came with your Ultimaker 2 should only be used for
firmware updates.
With the Ultimaker Original it is possible to print with USB
cable, but we do not advice you to do that. It is less reliable
and other processes on your computer influence the speed of
printing. When available printing with the Ulticontroller is recommended.

A2. Latest upgrades and fixes
Almost every month we do a software update where we introduce new
functionalities and improvements.
In the latest Cura 13.11.2
* Adjusted the gantry height to 55mm for the Ultimaker, as 60mm was 3mm to high for the default setup with an V2 hot-end in the Ultimaker Original.
* Added no-go zones for Ultimaker 2 glass clips, to prevent damage to the nozzles on the Ultimaker 2.
* Added ooze-shield for dual-color printing
* Added wipe tower for dual-extrusion
* Made sure the Ultimaker Original bed leveling wizard can not be used on the Ultimaker 2, as this causes problems.
Ultimaker 2 Firmware update version: 13.11-2
* Fixed Ultimaker 2 build volume offset so that you do not print off the glass plate.
* Slightly tweaked the filament change procedure so there is less chance of a blob staying behind.
* Slightly tweaked the SD-Card error problems, solving a rare case of
SD-Card read errors.
* Added LED settings to Tune menu, so you can tune down the LED
lighting during printing.
* Start heating the nozzles when the bed is nearing its final temperature, so the nozzles do not sit hot.
* Make sure all commands are finished before starting a print or changing
material. This could cause issues when you where too fast.

C4.Adjusting your model
When you have loaded your model you can change the size or orientation, the
following steps explain you the basic on how you can adjust you model on how
you want it to be.
Rotating your object
The left icon on the bottom of
the 3D interface is the rotation
button [1]. When you select and
click it, you can rotate the model
over it’s XYZ axis. You see also
more functions when you have
selected the rotation button.

printing.The second icon resets [2] the 3D models rotation. By click-select one
of the 3 orientation circles you adjust the rotation of the model. The rotation
degree appears in the number around the model. When rotating and clicking shift
you rotate per degree otherwise it’s per 15 degrees.
Scaling your object
The second left icon on the
bottom of the 3D interface is the
scaling button [1]. When you
select and click it, you can scale
the model in the XYZ direction.
The top icon that appears has
the function to scale your object
to max size [3] for your printer.
The icon above resets [2] the 3D
models rotation.
By unlocking [4] the lock you
have the possiblity to scale the
object in each particular
dimension.

give a right mouse click on it you
get some more functions.
With Delete object [1] [5] you
remove your model(s) from cura.
Center on platform [2] positions
your model in the center of the
build plate.
With multiply object [3] you
can decide to make more of the
selected object. If you number is
to much for the amount of space
on your build volume cura will
place it automatically it on maximum quantity.

There is also a function Split
object into parts [4], This function is used to split an model file
which contains multiple parts
4
into separate parts to be printed
one at a time. For example, if you
downloaded an STL file that contains 4 parts of a puzzle, you can
split it into 4 separate parts for
printing. For now it works very
slowly and you might need some patience to split objects, for now we advice your to split
parts in your 3D design program.

C5.Were Ultimaker 2 and Ultimaker Original differ in Cura
With the development of the Ultimaker 2 we decided that the print should know
what kind of material it has. That’s why when you insert material in your
Ultimaker 2 that you also should tell what material it is going to use. The printer
adjust its settings to the material requirements, in this way printfiles (gcode’s)
became material independent and can be easier shared with others. That why you
also had to make a decision earlier in the configuration. There is also a slight difference in the Cura interface and user flow which we will explain on this page.
Ultimaker 2
You can recognize and see that
you have configured Cura to
Ultimaker 2 if the print bed in the
visual interface shows the
Ultimaker 2 logo.
Ultimaker Original
You can see the difference in the
logo in the blue area.
More imporantly you can find
this back in it’s material
functionality. Where Cura asks
you the which material you are
going to use and what thickness
it has.
You will see more functions in
those materials when you put
Cura in Full settings (chapter E).
Note: most of the images being used are setup for the Ultimaker 2, so keep in
mind that the images in this manual may not be the same as the one in your
Interface. We will mention where you need to do take some extra action or where
it differs.

THE USE OF
FULL SETTINGS
AND
DUAL EXTRUSION
25
E1. Switch and use of full settings
With Cura we aim for a very simple and friendly experience for our users. The
more experienced you become with 3D printing and our software the more
specific you might want to work in the production of a 3D print. More specific
settings can al be managed through a full setting function we included in the
software. We will explain you this in the following steps.
1. First go in the menu bar to
Expert and select Switch to Full
settings.
Note: When your Cura is configured to
Ultimaker Original you have a fourth
tab, start/end-Gcode, were you can
change the begin and end process of
your printfiles.
2. You can see that you have
more features in 3 different tabs:
Basic, Advanced and Plugins.
Basic settings: Quality
The height of each layer [1]. For
print quality and printing time
this is the most important setting. Usual settings are 0.2mm
for a low quality print. 0.1mm for
a medium quality print. 0.06mm
for a high quality print. And
0.02mm for an ultra-high quality
print.
The thickness of the side shells
[2], when printing a simple cube,
this is the thickness of the side
walls. Increasing it improves the
strength of the part.

Vase by Marrit
Retraction [3] is pulling the
filament back when moving over
a gap in the print. This reduces the amount of thin lines between printed parts. These thin
lines are called strings. Retraction is usually always enabled, unless you want to print faster
or are printing with a material that does not allow retraction. Some models don’t require
retraction, this vase for example, because there are no gaps.
E1. Upload from Cura to YouMagine.com. The use of full settings and dual extrusion
26
Basic settings: Fill
The bottom/top thickness [1] is
the outer shell thickness on the
top and bottom. For example,
when printing a simple cube, this 1
2
is the bottom square and top
3
square thickness that are put
down. Increasing this will make
a stronger part, and depending
on your model, it will make for
better solid tops.
Cura fills [2] the internal parts of your model with a structure. This grid is made for
strength and to support the top layers. The amount of infill you want is influenced
by this setting. More infill produces stronger parts that take longer to print. If
strength is not a requirement then this setting could be put on 5% for a low density infill that can still support the upper layers.
Basic settings: Print speed [3]
Print speed sets the speed at which the print is put down. The default of 50mm
per second is a bit low for an Ultimaker. But this is a safe starting point. People
have printed up to speeds of 120mm per second. But this requires a well calibrated
and tuned machine.
Basic settings: Support
Supports are structures printed
Model from YouMagine
Vase by Marrit
below the print object to
support parts that otherwise
would be unprintable. There are
2 options, support structures
[4] that need to touch the build 4
platform, or support structures 5
that can also touch the top of
your model.
The platform adhesion type [5]
is a setting to help the printed object stick on the printer bed. Large flat objects
might get lose from the printer bed because of an effect called warping
(curled up corners in the print). There is the option to use a raft, which is a thick
grid under the object which scars the bottom of your print. Or a brim, which are
lines around the bottom of your object and because of the larger area the corners
are kept down. Brim usually gives the best results as it does not scar the object.
But it requires more space on the printer bed.
E1. Upload from Cura to YouMagine.com. The use of full settings and dual extrusion
27
E2. Advanced settings
Advanced settings are settings you usually only change once because you have
special needs that do not match the defaults.
Nozzle size [1] : The size of the
hole in your nozzle. The Ultimaker comes with a 0.4mm nozzle
by default. Some people drill the
nozzle to 0.6 or 0.8mm for faster
printing at lower quality.
1
2
3
4
5
6

8
Initial layer thickness [2] : The
thickness of the first layer. This
first layer is set by 0.3mm by default. A 0.3mm layer gives a thick
bottom layer which is easy to
stick to the platform and allows
for variation in the platform.
Bottom layer speed [5]: The speed at which
the print head moves while it is laying down the
first layer. This is done to make the print stick
easier.
Cut off bottom [3] : Cut the bottom of the model, this effectively
sinks the object into the printer
bed. If your object does not
have a lot of contact area with
the printer bed then this feature
could help you.
Infill Speed [6]: The speed at which infill lines
are printed. If set to zero then same speed is
used as for the rest of the print. A slight loss in
outer quality can be expected if you use this
to print a fast infill due to changes in nozzle
pressure when switching between outside and
infill parts.
Travel speed [4]: The speed
at which the printhead moves
when it is not printing. The
default is set on 150mm/s. But
a well calibrated and oiled Ultimaker can go faster and up to
300mm/s. It is not uncommon
for a printer to achieve 200mm/s
or 250mm/s travel speed. But
if you are seeing shifts in your
print then the travel speed might
be the cause.
Minimal layer time [7]: The minimal time spend
on printing a single layer. If a layer takes less
time to print then this configured time, then the
layer is slowed down. This ensures that a layer
is cooled down and solid enough before the
next one is put on top.
Enable cooling fan [8]: The cooling fan is usually enabled and greatly improves print quality
for PLA. For some other materials you might
not want to use the cooling fan at all and this
setting will disable it.
E2. Advanced settings. The use of full settings and dual extrusion
28
E3. Extra full settings Ultimaker Original
As earlier mentioned, with the Ultimaker Original selected in Cura you have some extra
functions that you can tune. With these settings you can take control on the material temperature and the diameter and flow of the filament.
Basic settings: Print temperature and Filament
The print temperature [1] : is the
temperature at which you print.
This setting has a lot of impact
on the print. The default is set
on 220C, which is a bit high for
1
PLA. For PLA you can go down
to 190C to reduce the amount
of strings on the print. But if you 23
want to print faster you might
need to increase the temperatufilament has an average of 2.89mm thickness.
re above the 220 degree.
The filament diameter [2] : is
the diameter of your filament.
Accurate measurement of your
filament gives better quality
prints. This needs to be known
up to 2 decimals. Using digital
calipers to measure you filament
improves results. Ultimaker
The filament flow [3] : is a correction factor
to make extrusion higher or lower then usual.
Some systems or materials require a correction
next to the usual diameter setting. This flow
adjustment can be used for this.
Advanced settings: Retraction
Retraction speed [4] : The speed
at which the filament is pulled
back when the printerhead
needs to move over holes.
Retraction distance [5]: The
amount of mm the filament is
pulled back when a retraction
happens. 4.5mm gives good
results on almost all Ultimakers
with PLA. Other materials might
need different retraction settings.

Note: At the Ultimaker 2 this is a fine tuned setting that
you don’t need to tune in Cura.
E3. Extra full settings Ultimaker Original. The use of full settings and dual extrusion

E4. Cura plugins
Since Cura version 12.11 there is support for plugins. This enables people to easily
include their own features, without having to modify the source code of Cura or
the slicer. Plugins are unavailable in quick print mode, you need to have some
experience. If you want to use it, click on the [Full Settings] mode under [expert] in
the menu bar at the top.
Check this link/button for the plugins:
http://wiki.ultimaker.com/Category:CuraPlugin
In the screenshot above you see a list of plugins (e.g. Skew, Tweak at Z and Wave).
These can be enabled by clicking on the arrow down button. The plugin will appear in the Enabled plugins box. There you can configure the plugin.

What is Gcode
GCode is the generic name for a control language for CNC (or Reprap) machines.
It is a way for you to tell the machine to move to various points at a desired speed,
control the spindle speed, turn on and off various coolants, and all sorts of other
things. It is fairly standard, and is a useful tool.

Start/End-Gcode
The start and end gcode are the startup and end procedure of the print. These
pieces of code influence the startup procedure and can be customized. By default
the printer is heated up, homed to the corner, and the head is primed. Editing this
requires knowledge of GCode.

E6. Dual extrusion for Ultimaker Original
The dual extrusion KIT is still experimental, which means tinkering for the best
result is needed. At the moment our slicer Cura does not support features recommended for PVA, like ‘wipe’. However, you can experiment with PVA in the dual
extrusion KIT by using another slicer program that does support it. Printing in dual
color is supported.Assembly manual can be found here.

When you are finished with installing the hardware part there are a couple of
steps in the software Cura that need to be taken off before you can really start
printing with your dual extrusion kit.
1. start Cura, go to File > Preferences and set the ‘Extruder
count’ on 2. You might have to
restart Cura before it will actually
take this setting.
2. Next, change the setting in the
Preferences panel to the ones
shown below (click the picture to
enlarge).
If your Dual extrusion is built
perfectly, the offsets should be
X= 0.0 and Y= 21.6 However this
being a DIY Kit, make sure you
play with the settings until your
second material sticks nicely
icely to your first material.
3. In the advanced tab you can
find a setting called Dual Extrusion Overlap, this has default
setting of 0.2 mm. With this
setting you can control how
much the colors should overlap.
This assures a good connection
in between two materials.
Now the settings in Cura are
done and you can start preparing your first dual extrusion
print!

4.Load the 2 models you want to
use for your print, either simultaneously or alternating. They
will both be placed on the build
platform.
5. If you click on the model and
right-mouse click the second
model you get the option: dual
extrusion merge. This will merge
both models into one model for
printing.
6. The model will be dual colored; in this case yellow equals
hot end 1 and red equals hot
end 2, since this is what is set in
the Preferences panel. You can
change the configuration by the
order in which you click during
the merge.
Now you’ve taken all the steps
and are ready to start printing
with your new dual extrusion kit!
If you have created some nice
dual extrusion print models feel
free to share them on our platform YouMagine, as we are very
curious to see what great stuff
you will create!
Cura13.11.2 included new function
for dual extrusion, wipetower
and ooze shield. Wipetower is
a small tower next to your print
where the nozzle wipes itself
clean when switching nozzles.
The ooze shield does the same
and improves this function but
with some models you don’t
want it because you can’t break
it away.
Know that both functions downgrade the printspeed.

software and as a user of Cura you will get a notification of that.
1. If you startup Cura and it gives
the following notification select
Yes to update. Your browser will
open a link to the latest software
and starts downloading right
away.
2. When you finished the installation wizard and start up Cura, it
takes over the machine settings
you had but with improved and
new functionalities of the latest
Cura version.

F2. Updating firmware of your Ultimaker
With the development of the Ultimaker Original we knew that the hardware was
very reliable and could print with a very high resolution. Besides that it still took
the team a few months to finetune the control of the electronic components in
combination with smarter software. The same applies for the Ultimaker 2 as we
keep on tuning settings the machine will become even better in the future. When
there is a new firmware version this will be communicated throught a blogpost or
you will get a notification in Cura.
1. When their will be new version
you can find this function install
default firmware under Machine
in the Menu bar.
2. Install default firmware or look
up the latest obtained
firmware file (.hex). Now Cura
will start uploading, this will take
around 15 seconds.
