3.9 Tuning the X Carriage
(Continues on next page)
In this step we will adjust the position of the two rear wheels
using the Eccentric Spacers located above them. The goal will
be to tune the tension between the Roller Wheels and the Base
Rail, so that the carriage moves smoothly and without slack.
The total range of adjustment on the Eccentric Spacers – from
overly loose to overly tight – is very small; only one half turn
total. Thus, when you do make adjustments, make very small ro-
tations.
To rotate the Eccentric Spacer you will use tool
#6
, the 8 mm
Low-profile Wrench, as in the previous case (§3.6 on page
1. Check each rear wheel to make sure that it can be rotated. If
it cannot, it is likely overly tight against the base rail. Rotate
the eccentric (
A
) in the direction necessary to loosen it.
2. Position your hands as shown (
B
), with one hand on each
side, and fingers directly in line with either the two left-side
wheels or the two right-side wheels. We will call these two
pairs
Pair 1
and
Pair 2
for reference in this step.
3. Keeping your hands in this position, try moving the carriage
back and forth in the direction indicated, for Pair 1 alone. You
you will most likely feel some slack movement in line with
these two wheels. Test the same way for Pair 2.
