Building the chassis

  • 3 2020 40cm extrusion profiles
  • 2 v-slot Profiles2020 40cm (for Z Axis)
  • 2 Extrusions profiles 2020 30cm
  • 6 small squares
  • 2 Double squares
  • 20 pcs M4x8 screws
  • 20 Pcs M4 TNuts

Use 6 small squares and pre mount the screws and TNuts

Do the same for the double squares

Tip

Move the squares on the corners. Yhe Tnut must be aligned with the extrusion profile groove.

Once properly aligned the TNuts will properly fit the groove and the square will naturally take it’s place

 

 

 


When you will tighten the screw, the Tnut will perfom 1/4 turn inside the extrusion profile as shown on the picture.

Check carefully that the TNut has performed the 1/4 turn so it’s properly locked with with extrusion.

 

Make sure the Tnut is properly positioned before finalizing your build.

When you unscrew the screws, the TNut must unlock and perform 1/4 turn on the other side. This will allows you to remove the square and the nut.


Chassis base

For the base of the chassis, you will need to use only 2020 standard extrusion profiles. Keep the Vslot (often black) extrusions for later.


Z Axis

The extrusions on both sides (here on the right and on the left) Are VSlots (often black)

The top extrusion profile is standard 2020 extrusion

Finish

List of parts

  • 6 end caps

use the 6 end caps as shown on the picture.

 

 

 

 


Start to push them by hand slightly.

 

 

 

 


Push them up to the end. use some force if needed. You may require an hammer to push them completely in some cases.
