Assembly

Assemble the lower carriage first (1). Note trapped nuts.

Then assemble the upper carriage (2).

Carriage-upper-assembly.PNG

Assemble the two halves together (3) using 6 M4x40 caps (don't forget the optoflag!). Tighten the middle two caps, keep the outer two pairs loose. When fully assembled use a piece of ø8 mm bar to set the distances between the bearings. Slide the bar between the bearings and tighten/slacken the outer two pairs of M4x40 caps to achieve a smooth, low resistance, running fit.

Finally assemble the extruder (4).

Assembly

Do not tighten the two adjuster bolts marked with a * in this diagram. These will be used to set the contact between the bearings and the Z shaft. If you attempt to tighten them now you may damage the bracket.

Assembly

Use the ‘side plate nut jig’ to trap the nuts for the bar clamp bolts. There is room between the jig and the side plate for washers on both sides.
