Adapter Afterburner cho Ender 5 với hotend Mk8

This is my take to fit an Afterburner on the Ender 5.

This mod doesn't require to get a new hotend or even move the hotend from its original position.

I used VORON's official STEP files and modified some parts and also added my own designs.

It should also fit the MicroSwiss all metal hotend and should also fit the Creality Spider V3 with some tweaking.

You may have to get a longer bowden cable because the Afterburner is higher than the original fan shroud.

Parts details

• Modified parts :
  • Enderburner Body Front

• Custom made parts :
  • Enderburner Adapter Plate : comes in two versions, with or without CR Touch

• Cable chain (Optionnal) :
  • Enderburner Y Chain Anchor

The blower and hotend fan housing were not modified from the original Afterburner so they are not included. You can retrieve the missing parts here : X Carriage Afterburner

You need : Blower Housing Rear, Blower Housing Front, Hotend Fan Mount.

BOM

• 21* M3x4x5 threaded inserts
• 2* M3x6
• 7* M3x8
• 2* M3x12
• 4* M3x16 (replace 1 M3x16 by a M3x18 if you want to include the cable cover)
• 4* M3x30

Assembly

The assembly is very similar to the original Afterburner. You will find a STEP file of the whole assembly as a reference.

To install the Adapter Plate you will have to remove the hotend assembly from the carriage plate. Then reinstall the hotend.

Installing the body on the adapter is similar to the original Afterburner. Slide it into the two top screws, then screw the other two from the inside the fan duct (see image).

Software setup

You don't need to change the firmware since the hotend hasn't moved. The CR Touch is almost at the same place so you don't need to modify the X and Y offset in the firmware either. Warning : from my own assembly, the Z offset is different from the original Ender 5, so you should be very careful and set the new Z offset before printing anything.

Material

The original Afterburner is highly recommended to be printed using ABS or ABS+, so I woulnd't recommend printing this model with PLA or PETG.

Printing settings

Use VORON default printing settings.

Like the original, supports are not needed except for the Cable Cover. I couldn't find a way to have two fixation points and not needing supports.
