21 Available languages
⬢Plug the printer and turn it ON.
⬢Completely unload the filament from the printer.
⬢To make handling the printer easier, lower the Z-axis to its lowest possible point.
⬢Firmware 4.4.0 and newer: using the LCD knob navigate to Control -> Auto Home.
⬢Up to firmware 4.3.4: using the LCD knob navigate to Calibration -> Auto Home.
Where can you find the firmware version? On the printer screen, navigate from the main screen to Info -> Version info.
Make sure the printer has cooled down to room temperature. Check the values on the printer's screen.
⬢Turn the printer OFF and disconnect it from the outlet.
The following steps will show how to replace the original input PTFE tube with a longer tube. Replacing the input PTFE tube for a longer one is optional, but recommended for easier filament insertion. If you don't want to replace the PTFE, skip to USB cable: parts preparation.
⬢Hold the extruder with one hand.
⬢Using your second hand, release two screws securing the extruder to the Z-carriage.
⬢Carefully take the extruder off the printer a place it next to it.
⬢Loosen the screw on the plastic part of the extruder. The screw does not need to be removed, just a few turns are sufficient.
⬢Pull out the input PTFE tube from the extruder.
If it is difficult to remove, use pliers to pull it out.
This step is intended for printers with the filament sensor. If your printer does not have the filament sensor, skip this step.
⬢Slightly loosen the top screw on the filament sensor.
⬢Pull out the longer PTFE tube.
If it is difficult to remove, use pliers to pull it out.
⬢For the following steps, please prepare:
⬢PTFE tube 4x2.5x360 mm (1x)
⬢It's recommended to mark the distance of 2.5 cm (0.98 inches) from the end of the PTFE tube before the insertion to the extruder. Both ends are symmetrical.
⬢Locate the hole for the PTFE tube on the side of the extruder assembly and insert the marked end of the tube all the way to the extruder. Check the correct insertion according to the marking on the tube.
You can use pliers for insertion. However, ensure a piece of filament is inserted in the PTFE tube to prevent deformation.
⬢Check that the PTFE tube is bent in the correct direction (see the detail).
⬢Secure the tube by tightening the M3x12 screw.
⬢Attach the extruder back to the Z-carriage.
⬢Hold the extruder with one hand and using your second hand secure the extruder by tightening two M3x25 screws. Tighten firmly.
⬢Slide the filament sensor onto the PTFE tube. See the picture for the correct orientation of the sensor.
⬢Check the position of the PTFE tube through the groove:
⬢Wrong installation. The filament sensor is not fully pushed onto the PTFE tube. The filament sensor will not work properly.
⬢Correct installation. The filament sensor is fully pushed onto the PTFE tube.
⬢Now, tighten the screw gently to ensure the sensor won't slide from the PTFE tube.
⬢Use a piece of filament and slide it through the filament sensor to ensure the proper functioning of the tube. In case of any resistance, release the screw slightly.
⬢For the following steps, please prepare:
⬢USB extension cable (1x)
⬢Zip tie (2x)
⬢Push the USB cable from the outside in through the rectangular hole in the bottom panel.
⬢Ensure the USB symbol on the connector is facing upwards.
⬢Press the connector fully into the hole with your thumbs. You should feel a slight click.
⬢Guide the cable along the right side of the Enclosure.
⬢Secure it with two zip ties. Do not overtighten the zip ties.
⬢In the following steps, we will insert the printer into the enclosure. Before that, we need to check the following:
⬢Z-axis is in the lower position.
Ensure that the nozzle does not touch the printing surface!
⬢Ensure the print head is in the rightmost position.
⬢If you have the filament sensor, you can temporarily hook it to the LCD. This will prevent it from getting in the way during insertion.
⬢Remove the USB stick from the printer.
⬢Carefully insert the printer inside the enclosure with its base facing forward. When doing so, be EXTRA CAREFUL to:
Ensure the X-end and aluminum Z-axis profile pass through the right and left cutouts of the front opening. Use EXTRA CAUTION to avoid damaging the printer or enclosure.
⬢Hold the heatbed with your left hand to prevent it from sliding down and getting damaged on the bottom plate.
⬢During insertion, carefully watch all sides of the printer to ensure nothing is in the way (e.g., cables, motors, etc.).
⬢Carefully place the printer on its feet. We will adjust the exact position later on.
Ensure that no parts of the printer touch the side panels to avoid scratches.
⬢From the back of the printer, connect the PSU power cable. See the correct orientation of the cable.
If the space is difficult to access, move the printer closer to the front, avoiding scratches on the panels.
⬢If necessary, connect an ethernet cable, which is optional.
⬢Connect the USB extension cable from the right side of the printer.
⬢Rearrange position of the printer like in the picture. The printer must be placed between all three anti-slip dampers.
⬢For the following steps, please prepare:
⬢Temperature sensor (1x)
⬢Thermometer-bracket (1x)
⬢M3x8 screw (2x)
⬢M3n nut (2x)
⬢Insert two M3n nuts into the Thermometer-bracket.
⬢Pull out the plastic tab from the temperature sensor.
⬢Insert the temperature sensor in the Thermometer-bracket. Push on it by your thumbs until you feel a slight "click". Avoid pressing on the screen, you can damage it.
⬢From the inside, mount the thermometer to the top left corner. Secure it with two M3x8 screws.
⬢For the following steps, please prepare:
⬢Spool-holder-r (1x)
⬢Side arm (1x)
⬢M3x12 screw (2x)
⬢M3n nut (2x)
⬢Completely insert two M3n nuts into the holes in the Spool-holder-r.
⬢From the inside, align the holes of the Spool-holder-r with the corner on the right side of the enclosure. Ensure the orientation is correct.
⬢Secure the Spool-holder-r with two M3x12 screws.
⬢Insert the side arm into the Spool-holder-r and turn counter-clockwise to lock it.
⬢And the very last thing, stick the silver label including the serial number on the rear side of the Enclosure.
⬢Locate the silver label with the serial number in your package.
⬢Place it on near the left bottom corner.
⬢You have successfully installed the printer into the enclosure. This requires a certain reward!
⬢Eat the remaining gummy bears from the third row.
⬢That's all! Great job. You have successfully assembled the Original Prusa MINI Enclosure. Now, let's try it out.
⬢On the right side of the printer, turn the power switch ON.
⬢You can now hang the filament spool on the spool holder and load the filament into the printer and start printing.
