Step 2
Take a small spirit level (A weighted piece of string will also work if you do not have a small
spirit level) and hold it against one the smooth rods on the outside on the Z Axis. Loosen the
M8 nuts next to the lower Z axis and move the axis until your Z Axis is level then tighten.
Repeat this for both of the Z Axis.
Step 3
Now measure then gap between your work surface and the base of the X End Motor Mount.
Make a note of this and then hold the coupling tight on that Z Axis. Twist the opposing Z Axis
coupling to raise or lower your X Idler Mount until it is the same height as the other X end.
If you have a spirit level you can use it to ensure your X Axis is perfectly level by place across
the ZX Axis smooth rods. Turn the Couplings until level.
