7: Cleaning the Datum Microswitches
X Axis Datum Microswitch.
The microswitch defining the X axis datum is positioned on the right
end of the rear X axis slideframe assembly, when viewed from the
front of the machine. The microswitch itself is hidden from view by
the extruded metal section, used to cover the drivebelt that connects
the front and rear X axis leadscrews. In order to reach the X axis
microswitch and trigger bolt, you must remove the access panel at
the rear of the machine (see photo below).

Using a soft bristled brush, carefully clean dust and debris away
from the microswitch, to an area where it can be removed using a
vacuum cleaner.
If the microswitch is being cleaned with the X axis at its datum
position, take care not to disturb the position of the trigger bolt attached
to the rear A frame assembly.
