8. Servicing the X axis
The axes are the most strained mechanical components in a laser engraver. As we
have to make sure that the precision is high enough to get a perfect engraving result
it is important that possible positioning errors between inremental resolver and
engraving head are minimized (engraving accuracy at 1000dpi=25.4µm, at cutting 1
increment=10µm).
To assure this, we have to service the axes periodically. The most important one is
the X-axis, as it moves approximately 500 times farther than the Y axis (this is true
for square jobs and a resolution of 500 dpi)
Each of the axes contains some parts of consumption. These are:
- Belts (motor belt and main belt)
- X-motor including drive gear
- Ball bearings
- THK guide
- X-gearing assembly
which have to be replaced regularely.
The following instruction contains all mechanical elements that might have to be
replaced. On every machine the technician has to decide which of the components
really has to be replaced. (For a smaller service replace only: belts and ball bearings)
