Fine Tuning
1. Adjust the tension of the build plate assembly on the Y-axis on the base
frame.
a. Check the tension of the build plate assembly. Hold the build plate
carriage under the build plate and try to wiggle it left and right. If the
build plate assembly wiggles back and forth on the Y-axis frame, it is too
loose.
b. To tighten the build plate assembly, rotate the three eccentric nuts that
connect the three wheels to the right side of the build plate assembly. Use
the open-end wrench to rotate the nuts slightly—a quarter turn is usually
enough—until each of the three wheels is tight against the Y-axis frame
and the carriage no longer rotates.
c. Re-check the tension of the build plate assembly. The assembly and the
belt should move forward and backward without much effort, but there
should have no side-to-side wiggle or play.
2. Adjust the tension of the gantry on the right pillar of the gantry frame.
a. Check the tension of the gantry assembly at the right pillar of the frame.
Hold the gantry and try to wiggle it up and down. If the gantry wobbles on
the right pillar frame, it is too loose.
b. To tighten the gantry, rotate the one eccentric nut that connects the
wheel to the inside of the gantry. Use the open-end wrench to rotate the
nut slightly—a quarter turn is usually enough—until the wheel is snug
against the frame pillar and the gantry no longer wobbles.
