Cleaning Glass Scales
If it is necessary to clean the glass scales on the MH3D, proceed as follows:
Cleaning the X Axis Scale
• Move the bridge to the rear of the
machine.
• Move the ZX cariage to one end
of its travel. Lock the machine's
axes.
• Clean the measuring scale with a
soft, anti-static cloth that is
moderately wetted with pure
alcohol. Use only Isopropyl
Alcohol. Allow the alcohol to dry.
NOTE: Do not use any other
type of cleaning fluid.
• Unlock the axes and move the
bridge or carriage to the other
end of its travel. Lock the
machine axes. Clean the exposed
part of the scale. It is important
that all residue be removed from the scale.
• Check all surfaces for smudges and reclean as required.
• Unlock the axes and move the ZX carriage to the middle of the X-axis rail and
lock the machine's axes.
Cleaning the Y Axis Scale
• Move the bridge to the rear of the machine. Lock the machine's axes.
• Clean the measuring scale with a soft, anti-static cloth that is moderately wetted
with pure alcohol. Use only Isopropyl Alcohol. Allow the alcohol to dry.
NOTE: Do not use any other type of cleaning fluid.
• Unlock the axes and move the bridge to the other end of its travel. Lock the
machine axes. Clean the exposed part of the scale. It is important that all
residue be removed from the scale.
• Check all surfaces for smudges and reclean as required.
Cleaning the Z Axis Scale
• Move the bridge to the rear of the machine.
• Lower the Z-axis rail to its lowest point.
• Lock the machine axes.
• Clean the exposed end of the measuring scale with a soft, anti-static cloth that is
moderately wetted with pure alcohol. Use only Isopropyl Alcohol. Allow the
alcohol to dry. It is important that all residue be removed from the scale. Check
all surfaces for smudges and reclean as required.
NOTE: Do not use any other type of cleaning fluid.
NOTE: Because the end of the scale on the Z-axis is not normally exposed
during operation, it is not anticipated that it will require periodic cleaning.
The scales are fitted with covers that must be removed before the scales can be
cleaned. Be sure the covers are cleaned and returned after cleaning the scales.
