Special Note:

This documentation was made for Greg’s extruder model and some additions were made to fit the currently provided MK8 bowden extruder.

Bowden MK8 extruder

Greg’s extruder assembled

List of parts

  • 1 Extrudeur already assembled (see full assembly here ici)
  • 2 M6x12mm screws
  • 2 T-nuts
  • [provided] 1 allen key

 

Start by preparing 2 set of screw/t-nuts so that they are located below the big gear wheel.

 

 

 


The goal here is to place it right next to the power supply unit on the top aluminum extrusion.

If you look at the printer from the front, the power supply should get to your right.

On this photo this is the back view.

 


Place the extruder so that the screws start to get inside the slots located below the aluminum extrusion.

The picture shows you an example.

 

 

For MK8 Extruder the process is very similar as shown on this picture, except that the motor is located in the opposite side.

 

 

 

 

 


The side view (right view) show the location of the T-Nuts, they should perfectly fit inside the extrusion slot.

If you already placed some side cover, remove it slowly with a flat screw diver, it’s interesting that it’s removed so that it will be easier for you to make sure the screws are properly attached. Otherwise the T-Nut on the edge of the extrusion might not turn and will not self lock.

 

For MK8 Extruder, again it’s very similar.

The stepper motor is below the top extrusion profile.

 

 

 

 


Here a zoom showing how it should fit inside. Those 2 screws will make the most of the work keeping this extruder in place.

 

 

 


Once properly inside the slots, screw it and add a side set of Screw+T-Nut .

You should be able to easily insert those even if sometimes the T-Nut won’t align properly with the screw.

 

 


Now screw it. It will maintain properly the extruder on the side and prevent it from vibrating.

 

 

 


Now you can put back the side cover.

The extruder might slightly go beyond the extrusion. So the side cover should align with the side of the extruder.

 

 

 


Push it in place to finish the assembly.

 

 

 

 

For MK8 extruder the back view should look like this picture.
