Aligning Axis
Sprockets
The X and Y axes are driven by timing belts that
connect an assembly of axis rails. If drive sprock-
ets are loose, the axes will not travel properly,
resulting in skewed print results. Tightening the
drive sprockets is normally sufficient to resolve
these issues.
The drive sprockets are secured to the axis rail by
(2) set screws (see Figure 64). Set screws must
be snug to prevent sprocket from slipping on the
axis rail.
