Notice about GT2 pulleys

The gt 2 pulleys on the pictures here are show only as an information. You will install them later on.

 

List of parts:

  • 3 extrusion profiles supports (plastic part)
  • 1 extrusion support with end stop (pièce plastique)
  • 8 x 625ZZ bearings
  • 8 x  M6x12mm screws
  • 8 x M6 TNuts
  • 4 GT2 16 teeth pulleys
  • 1 cable tie

Assembly process

Take the plastic part

Use 2x625ZZ bearings

These 2 bearings will be inserted inside specific grooves of the plastic part.

How to place the later GT2 pulleys

The GT 2 pulley will then come between the 2 bearings.

Special note:

In order to align later on the belt, the pulley will need to be laid against 1 of the bearings. In order to keep the symetric aspect of this part, you will get a small void between the other side of the pulley and the other bearing.

 

The location of the pulley will be explained later on

Repeat the same logic on the 2 other parts. You should get 3 identical parts.

End stop holder.

The procedure is the same here

The only difference is the special location where you need to install the end stop

Note however the location of the en stop wheel pointing up.

 

Warning, this end stop holder has been updated starting Avril 2017

Here is the new version

In order to keep track of previous parts,  here is the old version.(before Avril 2017)

Once assembled

Again the pulleys cann be held right now and are shown only for further comprehension

Preparing the nuts and screws

The final phase here is to prepare all the M6X12mm screws and their Tnuts that we will use later on.

You will need :

  • 8 x M6x12mm screws
  • 8 x M6 Tnuts

The side holes on the plastic parts are used to install these screws and Tnuts
