⬢The MMU3 unit should be placed in the middle of the top part of the printer's aluminum frame.
⬢Place the MMU3 unit onto the frame.
Attach it just by the top hooks.
Attach it just by the top hooks.
⬢Look from behind, there are "clamps", which will be used to lock the unit to the frame in the next step.
⬢Make sure the unit is in the middle of the frame. Once we engage the clamps, it won't move left and right as easily anymore.
⬢Press the back part of the MMU3 unit downwards slightly, until the clamps lock to the frame.
⬢Check that both bottom clamps on the unit are fully engaged.
If you need to remove the unit from the frame, simply lift the back part up to disengage the clamps.
Now, we will guide the cables from the MMU unit into the printer.
Make sure the printer is turned OFF and unplugged from the wall outlet. Do not ever connect or disconnect the MMU unit while the printer is ON.
⬢Introduce el haz de cables de la unidad MMU hacia la electrónica de la impresora. El cable debe colocarse justo al lado del bastidor de la impresora.
⬢Take the Ext-cable-holder-a plastic component. There is a small part that needs to be breaked off in order to make space for the MMU cable. Remove the part using needle-nose pliers.
⬢Similarly, remove the break-off part on the Ext-cable-holder-b.
⬢Loosen the two M3x10 screws on top of the cable cover.
⬢Guide the MMU/Printer cable through the corresponding opening into the xBuddy box.
⬢Plug the MMU/Printer cable into the corresponding connector on top of the xBuddy board.
⬢Attach the cable-holder-b back onto the xBuddy box using two M3x10 screws.
⬢Insert two new zip-ties into the marked opening on the inside of the xBuddy box. Make sure the zip-ties wrap around the cable bundle.
⬢Attach the cable-holder-a part using two M3x18 screws. Make sure no cable is getting pinched.
To verify the remaining cable connections are connected properly, refer to the MK3.5 assembly guide
⬢Ensure all connectors in the cable bundle remain fully inserted.
⬢Wrap the zip-ties around the cable bundle and gently tighten. Cut off the remaining zip-tie.
Secure the zip-ties snugly but not too tight to avoid the risk of accidentally disconnecting or damaging the cables.
⬢Alinea la tapa de la caja xBuddy con la caja xBuddy y fíjala con cuatro tornillos M3x6.
⬢Visita la página de la MMU3 en Help.Prusa3D.com
⬢Descarga el último pack de Drivers y Apps.
⬢¡Deja esta página abierta para los siguientes pasos!
⬢Instala el paquete descargado en tu ordenador y abre la aplicación de PrusaSlicer.
PrusaSlicer es parte del paquete de controladores. Incluye la herramienta de actualización del firmware. El paquete de controladores también incluye objetos de muestra para imprimir.
⬢Open the PrusaSlicer Assistant / Wizard. (Configuration > Configuration Assistant > Prusa FFF)
⬢Scroll down to MK3.5 Family and make sure that the corresponding printer + MMU3 option is selected.
The default nozzle is 0.4mm from factory.
⬢Click Finish to close the Wizard.
⬢In Printer: menu, select the MMU3 printer profile for future slicing.
Note, the MMU3 on MK3.5 is reverse-compatible with the older MK3S+ MMU3 or MMU2S Slicer profile and G-codes - but not with the MMU2 profiles!
You will need to update both the firmwares for the printer as well as the MMU unit. Use only a combination of the newest firmware versions for both devices together.
Please refer to the MMU3 Firmware Compatibility article to find out exactly which firmware version you need.
⬢Vuelve a Help.Prusa3D.com
⬢Descarga el último pack de Firmware para tu modelo de impresora.
⬢Open up the firmware bundle you have downloaded earlier. Open one of the folders dedicated to the MK3.5 printer (marked by MK35)
⬢There are two firmware files in the folder. One for the printer, the other one for the MMU unit.
⬢As a firmware file for the MK3.5, select the MK35 .bbf file
⬢Connect the printer to the electricity and turn it on.
⬢Now, let’s flash the printer’s firmware.
⬢To flash the MK3.5 printer, insert a USB drive with the firmware file into the printer. Then, restart the printer using the reset button.
⬢On the Firmware update screen, choose "FLASH" and wait for the process to complete.
⬢After finishing the firmware update, make sure there are no filaments loaded neither in the extruder, or in the MMU unit.
⬢Navigate to the LCD menu > Settings > MMU
and make sure the MMU is turned on.
and make sure the MMU is turned on.
⬢This option not only turns on the MMU functionality in the firmware, but also turns on the power for the MMU unit, which is necessary to do a FW update.
⬢From now on, the reset button on the printer resets also the MMU unit. Wait for a while, the MMU unit will go through the self-test routine. (accompanied by flashing LED lights on the MMU unit) Wait until it boots up properly, before issuing any commands to the printer.
⬢Since you've converted the extruder to the MMU version, when prompted to reconfigure the filament sensor's behavior, which will appear immediately, choose 'Continue'.
⬢Extruder type can be changed in Settings > Hardware > Extruder
⬢The MMU3 firmware file needs to be flashed into the MMU unit itself. Find the microUSB connector on the right side of the MMU3 unit.
⬢Connect the unit to your computer using the bundled microUSB cable.
⬢On your computer, select the appropriate MMU firmware file compatible with your printer model.
⬢Abre PrusaSlicer y selecciona Configuración ->Flashear Firmware Impresora en el menú superior.
⬢Hit Browse and select the MMU3 firmware image file on your computer.
(e.g. MMU3_3.0.0.hex)
(e.g. MMU3_3.0.0.hex)
⬢El puerto serie debería detectarse automáticamente.
⬢Presiona el botón de Flashear.
⬢Espera hasta que aparezca el mensaje ¡Exito al flashear!.
⬢Una vez finalizado el flasheo, desconecta el cable USB.
En caso de que tengas problemas al instalar el firmware, por favor visita el artículo para solucionar problemas.
In the following steps, we will calibrate the IR Filament sensor iside the Chimney on the extruder. Follow the instructions carefully, this part is very important!
⬢Con una llave Allen de 2.5mm, asegúrate de que el tornillo prisionero de la Chimenea no esté apretado. No lo quites del todo. Mantiene unida la chimenea.
⬢Apriete con cuidado el tornillo de calibración lateral para que la chimenea se desplace completamente hacia la izquierda.
⬢When tightening the calibration screw, the chimney moves to the left, making it less sensitive to triggering.
⬢When loosening the calibration screw, the chimney moves to the right, making it more sensitive to triggering.
⬢Tighten the calibration screw until the chimney moves all the way to the left.
⬢Inserta una llave Allen de 1.5mm en el extrusor. No la empujes hasta el fondo todavía.
Make sure you are using the thinnest of the bundled Allen keys; 1.5mm. Do not use the 2mm one!!
⬢Ve a Info > Info sensor > en tu MK3.5
El sensor Fil. debe indicar NINS (no insertada) cuando la llave Allen no está presionada hasta el fondo para que la puerta tensora no esté inclinada hacia fuera.
El sensor Fil. debe indicar NINS (no insertada) cuando la llave Allen no está presionada hasta el fondo para que la puerta tensora no esté inclinada hacia fuera.
⬢Ahora empuja la llave Allen de 1.5mm hacia abajo hasta que toque los engranajes Bondtech.
(no temas hacer fuerza hacia abajo para colocar la llave entre los engranajes)
⬢
La puerta del rodillo tensor a la derecha del extrusor debe inclinarse ligeramente hacia fuera simulando un filamento insertado.
La línea Fil. sensor en la pantalla LCD debería indicar el valor INS con la llave Allen (o un filamento) INSertada. Sigue soltando el tornillo de calibración hasta que INS aparezca en la pantalla LCD.
Luego, aflójalo otra media vuelta.
⬢By rotating the calibration screw, we need to fine-tune the chimney position so that the number on the LCD reliably changes when inserting and removing the Allen key or filament from the Bontech gears.
Calibrating the IR filament sensor is super-crucial in order for MMU3 unit to work properly!
Por favor, repite esta comprobación varias veces.
⬢Confirm the sensor works correctly: See the LCD again if the Filament sensor number
⬢muestra INS cuando la llave Allen (/filamento) se introduce hasta el final
⬢o NINS cuando no se introduce hasta el final.
⬢Cuando el sensor funcione de forma fiable y correcta, bloquea la chimenea apretando el tornillo de bloqueo desde arriba.
⬢Después de apretar el tornillo, verifica que las lecturas en la pantalla LCD siguen siendo correctas al insertar y retirar la llave Allen.
⬢Muy bien. Has calibrado tu sensor de filamento IR. Ahora, podemos pasar a calibrar el sensor SuperFINDA dentro del selector en la unidad MMU.
⬢For factory-assembled MMU3 units, the SuperFINDA is pre-calibrated, so you can skip the calibration steps.
⬢In the next step, we'll calibrate the sensor's position.
It is CRITICAL that both the filament sensor in the extruder and the SuperFINDA sensor function accurately. Otherwise, you will have trouble with the device.
⬢Use the inspection window on the selector to align the bottom of the sensor with the top of the window, as a starting point.
⬢When filament is in the selector, the steel ball rises and should be detected by the SuperFINDA sensor. Ensure the distance between the ball and the sensor is perfectly calibrated.
⬢Coge un trozo de filamento con la punta afilada e introdúcelo en el selector a través de la abertura roscada de latón de la parte delantera.
⬢Echa un vistazo a SuperFINDA desde arriba y fíjate en la lucecita roja del interior del sensor que se apaga cuando el filamento levanta la bola de acero de su interior.
⬢Red light = no filament detected = FINDA NINS / 0 / OFF
No light = filament detected = FINDA INS / 1 / ON
No light = filament detected = FINDA INS / 1 / ON
⬢If the light is still on, lower the SuperFINDA slightly.
If the light doesn't ever go on, raise the SuperFINDA probe by releasing the screw by its side, moving the probe, and tightening the screw back up.
If the light doesn't ever go on, raise the SuperFINDA probe by releasing the screw by its side, moving the probe, and tightening the screw back up.
⬢Watch the sensor readings on the LCD (Info > Sensor Info -> FINDA ) Note, there is a slight lag in the sensor's readings on the LCD; proceed slowly.
Repite la prueba introduciendo y extrayendo el filamento. Observa los valores en la pantalla LCD. Ajuste la altura de la SuperFINDA en consecuencia hasta que obtengas lecturas fiables del sensor cada vez que insertes y retires el filamento.
⬢Later on, an MMU error screen will show up if something goes wrong during the operation. See the example image; the first line describes briefly, what's the error about.
⬢prusa.io/04101 is a web address, where you can view a detailed article about the exact issue, and how to fix it.
⬢The status of the filament sensor is always displayed in the Footer section of the error screen to assist in diagnosis.
⬢Adjacent to it, you will find the status of the Finda sensor.
(Note the FINDA status reading on the LCD has a slight delay.)
⬢The bottom line are the solution buttons. Some errors have multiple solutions.
⬢You can also visit a detailed error description page via the QR code.
⬢MMU unit being in an error state is also indicated by its LED lights flashing.
⬢While in an ERROR state, the buttons on the MMU unit can be used to resolve the error too.
⬢The middle button usually replicates the LCD solution buttons function.
Note, if the MMU unit is in IDLE state, the buttons have a different functions; For example; If there is no filament loaded, the side buttons can be used to move the selector right and left. But more on that later.
⬢Para los siguientes pasos, por favor prepara:
⬢Tubo PTFE 360x2.5mm (1x)
The new PTFE tube has an internal diameter of 2.5mm. In case you are upgrading from the 2mm ID MMU2S tube, and you have trouble distinguishing between the old and the new one, try comparing the internal diameter of the two. See the second picture. The tube on the left is the new one.
A 2.5mm ID PTFE tube is required for the MMU3.
⬢M5-4 fittings (2x)
The fittings may have either a blue or a black collet. Functionally, they are the same.
⬢Attach the M5-4 fittings onto both sides of the new PTFE tube (4x2.5x360mm)
⬢Push the PTFE tube in fully.
⬢Consejo rápido: Si necesita retirar el tubo de PTFE del racor, presiona la pinza azul hacia dentro. Mientras la pinza está presionada, presiona primero el tubo de PTFE hacia dentro y, a continuación, extráelo por completo.
⬢Attach the PTFE tube onto the printer. One end goes onto the selector. The other goes onto the extruder. Tighten the fittings up using the Unikey.
Congratulations! The hardest part is over.
⬢The Buffer and spools setup in the picture is the one we will be trying to achieve. Arrange the spool holders and the buffer as seen in the picture.
⬢Hook up the "printer holder" part on the buffer to the extrusion on the printer.
⬢The PTFE tubes go from the spoolholders to the buffer. Then, from the buffer to the back of the MMU.
Note the spool holder positioning. It is important that filament has as straight path as possible and that nothing interferes. PTFE tubes should not be bent too much. Otherwise, the filaments will jam.
Note that due to the decreased filament friction in the MMU3 compared to the MMU2S, some of the 3rd-party MMU2S re-winding spool holders might no longer work with the MMU3.
⬢Connect the PTFE tubes from the MMU unit to the BOTTOM row of collets on the buffer, ensuring you match the numbering on both the buffer and the MMU unit.
⬢Attach each end of the PTFE tube from the Buffer to the PTFE holder on each Spool holder.
Make sure each spool holder is hooked up to the corresponding filament position number. (marked 1 to 5 on the MMU unit and the buffer.)
