X Drive assembly

  Find these parts.

  For the first steps we need the two parts

  on top and the on bottom of the picture

  Assemble the parts exactly as shown.

  Loosely mount the parts using four M4x12 bolts,

  washers and square nuts.

  Find two yellow plastic bushings.

  Insert them by hand in the direction as shown.

  Important: In the case they won't fit or go only half in,

  carefully pull them out and elargen the hole slightly with a file.

  Do not try to force the bushings in!

  This will very likely destroy them.

  Find a smooth rod and insert it into the bushings.

  Now tighten the bolts on the parts holding the bushings

  and test if the smooth rod goes through smoothly.

  You may need to re-align both several time to find the perfect alignment.

  Set aside for later.

X Idler assembly

  Find these parts.

  For the first step we need the

  three parts on the top of the picture

  Insert one plastic bushing into each one of these parts.

  Assemble exactly like shown.

  Loosely bolt the plates together using

  M4x12 bolts, washers and square nuts.

  Add the plate that was shown on the bottom right to the assembly.

  This part is not symmetrical, assemble exactly as shown.

  Loosely Bolt it together using four M4x12 bolts,

  washers and square nuts.

  Find a smooth rod and slide it through the bushings,

  now tighten the bolts and test if the smooth rod goes through smoothly.

  Find the perfect alignment.

  Now, find one M8 bolt (M8x25), and slide in in this order:

1. Big washer
2. 0.3mm shim
3. 608 ZZ ball bearing
4. 0.3mm shim
5. Big washer

  Slide it through the last part for the X idler.

  Secure with a M8 nut and washer.

  Add it to the assembly with two M4x12 bolts,

  washers and square nuts.

X Carriage assembly

  Find these parts.

  First, take the part shown in the bottom

  of the picture and find two short distance bolts.

Note for Version 2.1.2 owners: Leave the distance bolts out and continue assembly without

  The distance bolt is placed in the middle of the 3 holes on each side.

  Mount them with 2 M4x12 bolts (no washers).

  Tighten it well.

  Assemble the two bushing holders

  (the two on top from the first picture)

  in the direction as shown using two M4x12 bolts,

  washers and square nuts per side.

  Finally, insert the plastic bushings into the fitting.

  We recommend to push them in from the inside,

  as shown on the picture.

Also be careful here not to use too much force, and do not use pliers.
