Part 5 (shown in orange) is EM-W5B (form B M5 washer), which is thinner (0.75 mm) than the
 
−
regular washers (0.95 mm).  The thinner washers are packed in a separate bag, because
 
−
they are otherwise hard to tell apart (they are not painted orange in real life).
 
−
It is important to get the spacing of the X V-wheels exactly right, to match the distance
 
−
between the Vs of the MakerSlide, so please be careful to use the correct washers.
 
−
 
 
−
To assemble this, it's easiest to do the front plate first, one bolt at a time, following
 
−
the top exploded drawing.  Temporarily add a nut to hold those parts together.  Do all
 
−
eight bolts, then lay the plate down, Z V-wheels down.  Remove the nuts.  Offer the rear
 
−
motor plate (the one with the motor and idlers), and lower it
 
−
on the bolts, guiding them into the correct holes.  Finish by adding the eccentric spacers,
 
−
washers and nuts on the back of the carriage.
 
−
 
 
−
For reference, here's what goes on each bolt (two of each, eight total):
 
−

Insert the assembled dual X rail as shown, with the single T-slot on the front rail at the bottom and the one on the back rail at the top (this is marginally better at supporting a heavy spindle than the opposite configuration).  Adjust the X eccentric spacers until they V-wheels grip the MakerSlide firmly, but the carriage still slides smoothly.  Tighten the X V-wheel screws, re-adjusting the eccentric spacers in the process.  Leave the X rail in for the next step.
 
−
 
 
−
Insert the Z rail as shown (the orientation of the T-slot is not important).  Adjust the Z eccentric spacers so that the V-wheels grip the MakerSlide firmly, but the Z rail still slides smoothly.  Tighten the Z V-wheel screws, re-adjusting the eccentric spacers as necessary.  Remove the Z rail for now.
