This page is dedicated to the hot end Installation
Part list :
- 1 x assembled hot end (here E3D V6)
- 1 x inductance probe
- 4 x plastic screws (provided with hot end)
- 1 x fan provided with hot end
- 4 x M3X20 screws thermoplastic
- 3 x M3X8 screws thermoplastic
- 1 couple of plastic parts to support the hot end (here with the marking E3DI andE3DII)
- (not provided) 1 screws diver
This holder is re-using the original E3D fan holder .
The assembly on the chassis is very similar to the following procedure, just consider inserting the Blue part on the hot end heat sink first.
Look closely to the red arrow and you will notice that the holder has to be installed so that the non flat side is set toward down.
The following picture should show you more details.
Installation of E3Dv6 hot end on the carriage
The goal here is to screw the hot end support on the X axis carriage.
This part links the X axis carriage and the hot end .
It’s like a mould with an imprint for securing the hot end in place.
Those holes allows to screw the previous part in place. Depending on the height of your heat bed and also of the one of your hot end nozzle you might want to use a different set of holes to increase or decrease the height of the hot end of a few millimetres.
In our current situation we are going to use the holes located on the outside of the part on the lowest row. The picture will confirm the holes to use.
it should look like this one
Insert 2 M3X20 thermoplastic screws inside the holes on the side in order to keep the system attached
1 M3x8mm thermoplastic screw comes to strengthen the whole support
Now take the inductor support.
Note that on the new version of the plastic part, the inductive probe support has been removed and placed on the base holder instead.
Start to insert the 2 x M3x20 Thermoplastic screws inside the dedicated holes. The picture tells you which one to use.
This new plastic part is clamping the hot end inside it’s groove.
Skip this part if you have the new Holder system
Place this support on top of the hot end and don’t touch the Screws yet!
Place the 30mm fan (here on the picture 40mm) on the right side of the assembly.
Use 4 wood screws and slightly screw them loose so that the fan keep it’s place.
The front view should look like this.
No screws are tighten yet.
The fan will hold properly the inductor holder.
If you tighten the inductor holder first, the fan hole might not be aligned any more with it’s screws.
Once you have checked that all is aligned you can tighten the fan screws.
Note that the the screws of the inductor holder are yet not tighten.
Now you can finish to screw the inductor probe support.
The left screw should allow you to go a little bit further than the right one. It should make sure that the hot end is properly hold in place.
Now take the blower fan support as well as 2x M3x8mm screws (the shorter ones!)
This part allows to keep in place the blower fan in a vertical manner. It also guide the airflow toward the hot-end’s nozzle tip.
Same here, start to insert the screws until they reach the other side of the plastic part.
The holes we are using here are the one at the 2nd row of holes starting from the bottom.
Note that this part was made for AluHotEnd and mostly applies to E3D hot end.
As E3D hot end size is different from AluHotEnd you may need to use another set of holes. If you are not sure read the following steps below before doing anything.
This design allows to adjust the height of the air flow based on the hot end you are using.
Here the screw driver shows you the holes to use to fix the blower fan holder.
They are the 2 holes located below the one used to secure the inductor support in place.
On this picture, the second hole to use.
Now place the blower fan holder so that the screws are aligned with their holes.
Here also make sure to go easy with the screws.
The side views of the assembly
Now take the blower fan
Unroll the wires.
Place it on it’s support so that the fan output is placed toward the bottom.
At the top you will find 2 holes slightly shifted.
Place the fan so that the holding hole is aligned with 1 of the 2 holes on the support. Take the one you feel is best.
Use the last M4x20 screw (the bigger one) to keep the fan in place.
here we choose the top hole.
Once the blower fan in place, the setup should look like this picture.
The inductor probe comes last.
Remove the bottom nut and washer.
Take some time to place the remaining washer and nut slightly above the middle of the probe thread.
Insert the probe inside the last dedicated hole.
Try to place it so that the bottom blue end cap of it is slightly above the hot end tip. We will come back to it alter on when you will setup your electronics.
You can put back the washer and it’s nut to secure the probe in place.
Finish by placing the PTFE tube inside the pneumatic connector and you are done.
