Tri Colour 3D Printer
About this printer
The Dobot MOOZ-3 tri-colour printer is a unique product offering filament mixing
capabilities on a small heated bed. The printer comes with 3 colours for the CYM colour
space, which can be blended together within the nozzle to achieve a large range of
colours; The mixing modes also come in 2 styles:
Gradient mode, which will mix between 2 colours over a desired length.
Colour change mode, which will mix and form up to 4 different colours, changing
after each length.
We will go over the colour controls later in this document. Firstly, we will look at making
sure we get the connections and the zero point levelling correct.
Quick start printing guide
We always recommend reading the manual in entirety before printing, but if you already
have and want to get started with printing, have a look at this simple checklist:
1. Set up the printer by assembling and connecting the 3 extruder motor filament
mounts as shown, the X tower must connect into the port labelled “X”on the base
board.
2. Connect up the control and base station according to the diagrams below, with the
A-A and B-B leads. Notice that they do cross over.

3. Connect up the Nozzle, Heater, and fan connections.
Here, the red fan connects to [1], white fan to [2]. The thermocouple connects to
[H1] and the heater connects to [H2]. Fan [3] is left blank.
4. Once everything is connected properly, turn it on and make sure that it responds
to commands as expected.
5. Press the “ZERO POINT” button. The nozzle will centre and
approach the bed; once it has finished moving, adjust the nozzle so
that is some slight friction between the nozzle and the bed, using a
sheet of paper between them to test. (the nozzle should press onto
the paper and bed and make it slightly harder for the paper to pull out. The paper
should still be able to move, however, you should be able to feel the gentle
pressure from the nozzle.)
6. Press the “3 POINT LEVEL” button and set the 3-point balance with
a sheet of paper similar to above. The previous command is to set
the height of the printer, where this is now to set the position of the 3
arms so that it prints on an even surface.
7. Choose your gradient settings and press save. More information on
the gradient settings can be found in the colour settings section of
this document.
8. Use one of the example models we have online, or follow the instructions on the
next page to set up CURA for printing your own model.
Setting up CURA software
It’s important to get the latest version of CURA to get the best software in terms of quality,
bug fixes, and otherwise. CURA can be downloaded for free from:

In order to get the Dobot MOOZ-3 printer working with CURA, we must add a “new
custom printer” to CURA with the following settings:
(note the important values highlighted in blue)
To CURA, this is simply a 1 nozzle printer that prints in the same colour. All the colour
mixing options are done by the printer, not by CURA.

How to change the colour settings
Once you have set up the printer and you’re ready to set your colour
options, you can press the gradient button to bring up the colour menu:
In this menu you have a few
options:
Switch will switch between
up to 4 colours; you can press
each colour and set the
value, and change the bottom
value to be the distance that
you want to change.
Gradient will fade between
two colours over the distance
that you specify.
Once you have set your
desired parameters, press the
middle “save”button to save
the parameters. The machine
will now print according to
these specifications until you
either change or reset the
machine.
The printer will lose colour
settings after each turn-off.
Examples:
To the left we have a model that has been set to
switch with the colours:
(Magenta, Yellow, Green, Blue) at 5mm distance
To the right, we have a gradient with Yellow to
Magenta over a distance of 95mm.

Software Updates:
We do have one software update that might be useful if you find that it is not quite printing
in the colours that you expected.
You can find the software update online. To update, simply place the .bin file on a blank,
FAT32 usb stick and insert it into the machine while the machine is off.
When you turn on the machine, the firmware should update to the latest version.
