(19.3) Assembly of the E3D HotEnd.

E3D-V6 HOTEND ASSEMBLY BIGBOX.jpg


This is only a rough assembly guide. For full instructions please read the Hotside Documentation.


There are two options available:

  • lite6 (Lite)
  • V6 (Pro & Dual).

The only major variation for build purposes is the lite6 has the Heat-Break integrated into the Heat-Sink, so there is no heat break to add and no thermal paste is required.

Thermal paste applied to the Heatbreak.

V6 Only

Apply the thermal paste to the Heat-Break and screw it into the Heat-Sink.

Do not apply thermal paste to the thread that screws into the Heater Block.

Heater Block.
  • 1 x Grub Screw (Extruder Box, Hotend Fixings).
  • 1 x M3 x 10mm Button-Head Screw (Extruder Box, Hotend Fixings).

Screw the fixings into the heater block.

Part-Assembled.

Thread the Heater-Block onto the Heat-Break.

The top of the Heater-Block needs to be level with the end of the Heat-Break thread.

The Heater-Block must not touch against the Heatsink.

Measured to length.
  • 1 x PTFE Tube (Extruder Box, Hotend Bag).

Cut the PTFE Tube to 63mm.

Note: If you are assembling the HotEnd for a Dual cut the PTFE to 66mm.

Metal components.

Fit the Nozzle to the Heater-Block, push in the Bowden Clip and insert the PTFE tube.

Clip.

Raise the Bowden Clip out the top of the HotEnd while making sure the PTFE stays pushed down. Doing this will stop the PTFE moving around and help prevent blockages.

Hold the bowden clip up away from the body with the loop on an opened-up paper clip slipped under the lip of the bowden. With the clip locked up, push the ptfe tube down. Remove the paper clip and test that the ptfe tube does not move slightly up and down. If it does hold the bowden up again with the paper clip and push on the ptfe tube firmly down to seat it properly.

(19.4) Installing the HotEnd.

Lay the printer on to it's side and feed the cables through the Strut.

Too tight.

Move the printer back onto it's base and push the Printhead to the very front left position, marked 0,0 on the Printbed.

The cables from the Printhead will most likely now be too tight.

Correct lengths.

Carefully pull the cables back so there is enough slack in the cables.

Note: You will probably need to hold the Y-Axis Motor Cable to make sure it isn't dragged back when you pull the Printhead cables back.

Cable Tied.

Close and tighten up the remaining Cable Ties on the Spine.

Poked through.
  • 1 x Cable Tie (Bag 1).

To help keep the Filament Feed Tube and Printhead Cables in tip-top condition and to help stop them slopping around we can use a Cable Tie to keep them grouped together.

At the apogee of the group push the end of the Cable Tie through the edge of the Braided Sleeve.

Both Sleeves.

Push the end through the other Braided Sleeve.

Closed loop.

Close the Cable Tie around the Filament Feed Tube and cut off the excess.

  • 2 x M3 Square Nuts (Bag 6).

Slide one of the previously assembled Print Cooling Fans onto the X-Carriage.

Affix with the Nuts.

Fan.

Tip: The Square nut at the back can be a little tricky to get on. I find removing the lock washer from the M3 Screw and refitting gives a little more thread to grip onto. Use tweezers to hold the nut.

Once the nut is in remove the Screw again, pop back on the lock washer and carry on...

Fan.
  • 4 x M3 Square Nuts (Bag 6).

Attach the other fan to the opposite side and also affix the IR Sensor to the X-Carriage.

(20.2) Assembly of the E3D HotEnds.

E3D-V6 HOTEND ASSEMBLY BIGBOX.jpg


This is only a rough assembly guide. For full instructions please read the Hotside Documentation.


Thermal paste applied to the Heatbreak.

Apply the thermal paste to the Heat-Break and screw it into the Heat-Sink.

Heater Block.
  • 1 x Grub Screw (Extruder Box, Hotend Fixings).
  • 1 x M3 x 10mm Button-Head Screw (Extruder Box, Hotend Fixings).

Screw the fixings into the heater block.

Part-Assembled.

Thread the Heater-Block onto the Heat-Break.

The top of the Heater-Block needs to be level with the end of the Heat-Break thread.

Measured to length.
  • 1 x PTFE Tube (Extruder Box, Hotend Bag).

Cut the PTFE Tube to 66mm.

Note: If you are assembling the HotEnd for a Pro cut the PTFE to 63mm.

Metal components.

Fit the Nozzle to the Heater-Block, push in the Bowden Clip and insert the PTFE tube.

Clip.

Raise the Bowden Clip out the top of the HotEnd while making sure the PTFE stays pushed down. Doing this will stop the PTFE moving around and help prevent blockages.

Two.

You'll need to assemble two HotEnds.

(20.3) Installing the HotEnds.

Align.
(20.3.1) Align the PTFE with the hole in the X-Carriage.


Fit.

Push in the HotEnd.

Do not push in the HotEnd while holding the Heater Block.

Note: If the HotEnd will not push in all the way, check the grub screws are not stopping it.

Adjust.

Insert the other HotEnd.

Make sure they are fully inserted.

Check the orientation of each HotEnd so they match up with what is shown in the image.

Tighten.

Tighten up the Grub Screws holding in the HotEnds.

Tighten.

Do not forget the rear grub screw.

Note: When tightening the grub screws try to make the tightening as even as possible between the front and rear grubs, too much on one grub could cause the HotEnds to be positioned at and angle. You will also need to make sure the left nozzle is slightly higher than the right. This is done to make the nozzle alignment process in the commissioning stage a little easier.

Level.

Both HoteEnds should be at a similar height with the left extruder slightly higher.

PT100 & Heater.
  • 1 x PT100 (Extruder Box).
  • 1 x Heater Cartridge (Extruder Box).
  • 1 x Grub Screw (Extruder Box).
  • 1 x Button Head Screw (Extruder Box).

Insert a PT100 and Heater Cartridge into the Heater Block.

Secure using the provided grub and button head screw.

Note: Align the Heater Cartridge with the wires in a vertical configuration.

Bend.

Bend the Heater Cartridge cables as shown.

Do not bend the PT100 wire.

Run.

Pass the cables up through between the GT2 Belt and the 8mm Rod.

Cable Tie.
  • 1 x Cable Tie (Bag 1).

Put a Cable Tie through the hole as shown.

Fan.

Assemble a Hotend fan as shown in the photo.

NOTE that there is a slight cutout (chamfer) on the (blue) fan shroud. This cutout should be aligned with the wires going into the fan body such that when the shroud is fitted to the heatsink with the wires at the bottom, the cutout is at the bottom facing the heater block.

Fan.

Assemble the other Fan with the wires coming out from the other side.

Fans.

Clip the Fan to the HotEnd.

Take particular care not to clip the fan on too low, IF THE FAN IS ATTACHED TOO LOW IT BLOWS ON THE TOP OF THE HEATER BLOCK.

(29) Y-Axis Frame Endstop

Base.
  • 1 x Y-Axis Endstop (Printed Part).


Base.
  • 1 x M3 20mm Screw (Bag 9).

Fit the screw into the endstop. Make sure the screw fits all the way through the hole.

The screw is a very tight fit. You may find it helps to run a 2.5mm drill through the hole. It may take a 2.6mm drill or a little filing too so that you don't split the printed part.

Note the direction the screw is fitted to the part. It is the opposite side to the slots for the square nuts

Fitted.
  • 2 x M3 12mm Screw (Bag 9).
  • 2 x M3 Square Nut (Bag 6).

Attach the endstop to the frame (front right side). HINT... The screws fit from the outside top right front.

(32.1) Shaft Couplers

Couplers.
  • 2 x 5mm - 8mm Aluminium Couplers (Motion Box).

Get the two couplers from the Motion Box.

Remove the grub screw from the 8mm (upper) end of each coupler. This removal is listed later when the coupler is fitted, but removing the grub screw now off the printer saves the grub screw dropping inside the printer by accident.

THESE GRUB SCREWS YOU HAVE JUST REMOVED ARE NOT NEEDED AGAIN, DO NOT REINSTALL THEM.


Allen key.

Place an Allen Key or a suitably sized spacer over one of the holes where the Z-Axis Motors protrude.

You can use just about anything. This is simply to space the couplers.
