Step 2 Handling Hot Components Safely

CAUTION: Some subsequent steps involve handling the heated nozzle. It is crucial to proceed with extreme caution to avoid the risk of burns.

We will always inform you when instruction steps involve handling hot parts.

Take care when working on parts that are heated.

Avoid touching hot parts!

While the nozzle is heated and placed on the heatbed (carboard box), DO NOT leave the printer!

Step 3 Tools necessary for this chapter

⬢For this chapter, please prepare:

⬢T8 Torx key

⬢2.5 mm Allen key

⬢Universal wrench

⬢Wrench 13-16

⬢Nextruder box as a heatbed cover.

⬢Small brass brush for cleaning the nozzle

Step 4 Select the tool

⬢On your printer, go to Control -> Pick/Park tool.

⬢Select the tool on which you wish to install the V6 Nozzle Adapter.

We'll use "Pick Tool 1" as an example.

Step 5 Filament unloading

⬢If you have loaded the filament, unload it from the hotend. On the screen, navigate to Filament -> Unload Filament.

⬢Select the tool that you picked in the previous step.

The selected tool will automatically move to the front of the printer.

WARNING: The hotend and heatbed are very HOT. Do not touch these parts!!!

⬢Remove the filament from the hotend. It is not necessary to completely remove it from the printer. Just a few centimeters (inches) above the extruder.

Step 6 Cleaning the hotend

WARNING: The hotend and heatbed are very HOT. Do not touch these parts!!!

For the following steps, it is necessary to have the heaterblock and the hotend clean from the remains of the filament. Otherwise, it can be difficult to release the nozzle.

If you have a Prusa hotend sock on the hotend, remove it.

⬢Using the brass brush, carefully clean the heaterblock and the hotend from the filament residue. Avoid contact of the brush with the hotend cables, as this could cause a short circuit.

⬢When the heaterblock and the hotend are perfectly clean, cool down the printer. On the screen, navigate to Preheat -> Cooldown.

Wait until the hot parts are cooled down to ambient temperature. It takes approximately 10 minutes.

Step 7 Park the tool

⬢On your printer, go to Control -> Pick/Park tool.

⬢Select Park Current Tool.

Step 8 Preparing the printer

Before you proceed, it is recommended to protect the heatbed.

⬢Make sure the heatbed is cooled down to ambient temperature. Place the empty cardboard box approximately to the front center part of the heatbed.

⬢From the rear side of the printer, turn the power switch OFF (symbol "O").

Step 9 Undocking the Nextruder

⬢On the selected, cleaned tool:

⬢Gently undock the Nextruder.

⬢Put the Nextruder on the heatbed.

Step 10 Disconnecting the hotend

⬢Release the screw holding the dwarf-cover-door using a 2.5mm Allen key. Do not remove the screw, a few turns are enough.

⬢Open the dwarf-cover-door to access the electronics board.

⬢By pressing the safety latch, disconnect the hotend thermistor cable.

⬢By pressing the safety latch, disconnect the hotend heater cable.

⬢Leave both cables free for now.

Step 11 Removing the hotend

⬢Insert the TX8 Torx key all the way through the tool-changer until it reaches the grub screw in the Nextruder. Loosen the screw. Do not remove the screw, a few turns are enough!

⬢Carefully pull the hotend assembly out of the Nextruder.

⬢At the same time push the hotend cables behind the fan out of the Nextruder.

Step 12 Removing the Prusa Nozzle

⬢Using the 13mm cutout in Universal wrench X grasp the heaterblock.

⬢Using the 7mm cutout in the Universal wrench Y grasp the nozzle and loosen it.

⬢Manually release and remove the nozzle with nub from the hotend assembly.

Step 13 Installing the V6 nozzle: parts preparation

⬢For the following steps, please prepare:

⬢Nextruder V6 Nozzle Adapter (1x)

⬢V6 Nozzle (1x)

Step 14 Installing the Nextruder V6 Nozzle Adapter

⬢From the side with cables, screw the Nextruder V6 Nozzle Adapter to the heaterblock.

⬢Hold the heaterblock in your hand and tighten the Nextruder V6 Nozzle Adapter by the universal wrench.

⬢From the opposite side of the heaterblock, screw in the V6 nozzle. Do not tighten it completely. Leave a 2 - 3 mm gap between the nozzle and heaterblock.

The final tightening of the nozzle will proceed later. Please continue to the next step.

Step 15 Installing the hotend

⬢Insert the hotend assembly into the Nextruder.

⬢Push the hotend cables behind the heatsink fan up to the electronics.

⬢Connect the hotend heater to the upper slot on the electronics board.

⬢Connect the hotend thermistor to the lower slot on the electronics board.

⬢Close the dwarf-cover-door.

⬢Tighten the M3 screw using a 2.5mm Allen key.

Leave the hotend assembly free, we'll adjust the hotend angle later.

Step 16 Turning the printer ON

⬢Leave the Nextruder on the heatbed.

⬢From the rear side of the printer, turn the power switch ON (symbol "I").

The fans on the nextruders will turn on, that's all right.

Step 17 Heating the nozzle

In the following steps, we will need to heat up the nozzle. Avoid touching the HOT parts on the hotend.

⬢On the printer screen, go to Control -> Temperature -> select the nozzle and using the knob set 250°C.

DO NOT leave the printer!!!

WARNING: From now, the hotend is very HOT. DO NOT touch this parts!!!

Pay attention to everything around the hot end. Keep away the children!

Make sure there are no objects around the nozzle that could be damaged or injured by the high heat!

⬢Proceed to the next step.

Step 18 Tightening the nozzle

WARNING: From now, the hotend is very HOT. Do not touch this parts!!!

Do not use too much force. You could break something and burn yourself!

NOTE: The Nextruder can move freely on the box.

⬢Grasp the heaterblock with the wrench 13-16. Avoid pulling on the hotend!

⬢Tighten the nozzle using the universal wrench. Do not overtighten it, you can damage the thread. Use the sufficient force. The prescribed tightening torque is 1.5 Nm.

NOTE: Avoid bending the hotend assembly while tightening! After that, there will be a gap of approximately 1 mm between the nozzle and the heater block.

⬢Cool down the printer. Go to Preheat -> Cooldown.

Step 19 Adjusting the hotend

Make sure the nozzle is cooled down!

⬢Set the angle as close as possible to the initial 45° of the hotend assembly. Look at the picture.

⬢Using a TX8 Torx key, gently tighten the grub screw holding the hotend assembly in its place.

⬢Well done! The Nextruder is ready for docking.

Step 20 How to dock the Nextruder

⬢Take the Nextruder and place it carefully next to the dock.

⬢Place the two metal inserts through the white holes in the dock. The magnets will help you dock the Nextruder.

Step 21 Setting the nozzle diameter

⬢If you have replaced your nozzle twith the one having a different diameter, you have to change the nozzle diameter setting in the printer’s menu too.

⬢Go to Settings -> Tools -> Tool -> Nozzle Diameter and set it to the corresponding size.

⬢When slicing in PrusaSlicer, make sure to have the correct nozzle diameter selected in the Printer: menu.

⬢To add other nozzle diameter versions of the printer profile in PrusaSlicer, hit the small cog icon and select Add/Remove Presets. Then, select the nozzle diameters you are going to use.
