Filament preparation
¡Ahora podemos cargar los filamentos e imprimir el objeto de prueba! Pero antes;
Prepara al menos cinco filamentos de PLA diferentes y corta los extremos para formar una punta afilada en cada uno - como se ve en la imagen.
Los filamentos deben tener una punta afilada para poder cargarse correctamente tanto en la MMU como en la impresora. Si la punta está deformada, doblada o tiene un diámetro mayor, no se cargará correctamente.
Inspecciona los últimos 40cm (15") de cada filamento. Asegúrate de que no está sin deformaciones en ella. A veces, si el filamento se atascó antes, la rueda de la polea hace una hendidura en él. Esta parte del filamento ya no puede ser agarrada y movida por la unidad MMU y debe ser cortada.
Si el extremo del filamento está doblado, enderézalo. Debe estar perfectamente recto.
Utiliza únicamente filamento de alta calidad con una desviación de diámetro baja garantizada. En caso de que tenga problemas de carga/descarga de filamento en el futuro, vuelve a revisar este paso también. Asegúrate de que el filamento está seco. Los filamentos sensibles a la humedad pueden ser problemáticos durante el funcionamiento de la MMU.

Coloca los cinco filamentos en los portabobinas. Asegúrate de que las bobinas no interfieran entre sí.
Filament positions are labeled 1,2,3,4,5 from the left to right, from the user's point of view.
Ajusta cada portabobina de forma que la bobina encaja correctamente en los rodillos.
Verifica que el bobina puede girar libremente y que nada interfiere.

Take the cassette for filament 1 out of the buffer.
Insert the tip of the filament into the bottom PTFE tube attached to the spoolholder.
Keep pushing the filament into the PTFE tube until it appears in the corresponding buffer cassette.
Take the tip and insert it through the cassette into the other PTFE tube, which goes into the MMU unit. Don’t push it all the way into the MMU yet.

Preloading a filament to MMU

On the printer, go to the Menu -> Preload to MMU

(Filament -> Preload to MMU on MK3.5/MK4)

Select Filament slot 1. The MMU unit will engage the idler into the first position and start rotating the pulley until the filament is loaded in.
Keep pushing the corresponding filament end into the PTFE tube from the buffer into the MMU, until you feel the filament being pulled in.
Remember, the filament tip must be straight and sharp in order to load it properly.

After a given filament is successfully loaded into the MMU, return its cassette back into the buffer.
Repeat the same process for the other filament positions, until you successfully load all five filaments into the MMU.
Pro tip: Loading using the buttons.

También puedes cargar un filamento en la MMU utilizando los botones de la unidad. La próxima vez que cargues un filamento, utiliza el método que prefieras. Ya sea desde el menú LCD, o utilizando los botones físicos.

Mientras la MMU está inactiva; (indicado por TODAS las luces LED APAGADAS)

El botón central inicia o aborta la carga de filamento en la MMU.
Los botones laterales mueven el selector a izquierda y derecha para cambiar las posiciones del filamento.
Utiliza los botones laterales para desplazar el selector a la posición de filamento deseada, indicada por la alineación del selector con una de las líneas de la placa de identificación.
The ongoing loading process is indicated by a blinking green LED light for the respective filament position.
Stable green LED light means the given filament is loaded to extruder.
Note, after you issue a command to the MMU unit, wait and let it finish the operation. Don't rush. Don't play around with the printer in the meanwhile. Let it finish first if the MMU unit does something (homing, loading, unloading).

Go to the Menu > Settings > Loading Test

or Control > Loading test (on MK3.5/MK4)

Select the filament type to preheat (PLA)

Select Load all / Test All

Or test all the filaments from 1 to 5 manually, if "Test All" item is unavailable on your firmware version.

The MMU unit will now load and then unload all five filaments to see if all work correctly.

On the MK3.5 / MK4 printer, you can check the filament sensor's status in the "footer" area of the LCD screen to see if it's detecting the filament correctly.
While your MK3S+ loads a filament into the extruder, it performs the loading check: Solid blocks should be generated on the bottom of the LCD representing the IR filament sensor detecting a filament during the process.
If there are lines instead of some of the solid blocks, it means the Filament sensor in the extruder is providing an intermittent reading and might require some aditional tuning.
En caso de que fallen varios reintentos de carga, aparecerá una pantalla del error correspondiente.

IMPORTANT: This step is necessary for the MK3S+ / MK3.5 if you worked on the extruder head previously. If you only upgraded the old chimney to the new one, you can skip to the next step and use the Live Adjust Z function as usual to fine-tune the first layer.
Go to LCD Menu - Calibration - Calibrate Z.
A continuación, ejecuta la Calibración de la primera capa.

Printing a test object
We need to print a test object to verify that everything works correctly. Don’t worry, it will be a quick print.
Visit MMU3 Test objects on Printables.com
In the Print files section, download a G-code file pre-sliced for your printer model.
Save the .gcode or .bgcode file onto a storage media and print the test object.
Tools Mapping (MK3.5 / MK4)
Tools Mapping (MK3.5 / MK4)
Tools Mapping (MK3.5 / MK4)

When you start a print on the MK3.5 or MK4, the Tools Mapping screen appears. This allows you to reassign the extruders with the specified color to another one as needed.

On the left side, you'll see a list of the required materials and their colors, as specified in the G-code file.

On the right side, you'll find a list of materials currently available on the printer, that will be used to print the object. 

For example, if the G-code requires orange filament in the first position, but you have orange loaded in the fifth position, select the first position on the left menu and then assign it to the fifth position on the right.
Toca dos veces las posiciones de filamento o utiliza el codificador para seleccionar el número del filamento.

Start the print and wait until it finishes. In the meantime you can take a look at the printed Handbook.

All the information regarding calibration, how to organise the printer, buffer, spools, or troubleshooting tips are all in the printed or online Handbook.

To download the Handbook or if you encounter any issues, please visit our knowledge base at: http://help.prusa3d.com/en/tag/mmu3/

If you are having any issues while printing, follow the on-screen instructions or visit the link from the LCD screen.

Already printed all the bundled multi-material models from us as well as those seen at http://Printables.com? Time to print your own designs!
The simpliest way of making a single-body object colorful is the MMU Painting function in PrusaSlicer.
Basic steps for the manual method are described in our  G-code preparation for multi material print section.

For printing logos or text labels, you might also find the  automatic color change at a given layer height useful. Simply, slice an object, select a certain layer height, click the small orange "+" icon next to the height marker and select the desired MMU filament position (Extruder number).

If you have designed a model with multiple bodies, you may find the Exporting model from Fusion 360 guide useful.
If you are designing a single-body model, part of which should be MMU-Painted, make sure there is a sharp line surrounding each distinct part so that you can use the MMU Painting's Smart-fill function later on in PrusaSlicer.

If you have an intricate STL file that can't be MMU-Painted easily, you can try the more sophisticated way of Splitting STL with single compact part or Splitting STL into multiple parts using MeshMixer.

Did you know that MMU3 unit can also be used to make single-material printing more convenient too?
Puedes dejar hasta cinco de tus materiales favoritos cargados en la unidad MMU.
En la MK3.5/MK3.9/MK4, utiliza el perfil normal MK3.5/MK3.9/MK4, al laminar. La impresora te permitirá elegir qué filamento utilizar.
En la MK3S+, lamina un objeto con el perfil MMU3 Single y comienza la impresión. Luego, elige qué filamento usar desde el LCD.
If you know which of the five materials to use already while slicing, you can use the MMU3 profile and assign a single color (Extruder number) to the object.

If a filament runs out, your print can continue automatically using the SpoolJoin function. For more information, refer to the SpoolJoin article.

Now, you can finally have some Haribos, while you watch the printer print.
