The protective housing for these fixed mirrors moves with the laser
tube and X-axis rail to allow the laser beam to travel along the Y axis.
The laser head holds the 3rd mirror, focus lens, and air assist outlet
and directs the laser beam down into your materials. Its components
are normally protected by a rectangular shell that locks magnetically
into place.
The X-axis rail supports the movement of the laser head left and right
across the workbed. When using either of the rotary axes, this rail
should be positioned to connect the matching arrows.
This switch stops your laser when the debris tray is removed. For
pass-through and rotary engraving, close this switch using the
nearby bracket.
This pump circulates your water or laser-safe coolant through the
laser tube to keep it cool and stable.
This tank helps keep your laser tube cool and stable. It arrives full of
OMTech antifreeze but can also be replaced with distilled water.
This circuit board located under the left panel controls the engraving
process, responding to commands from your computer's engraving
software. It has a total memory of 128 MB, about 95 MB of which is
available to store designs.
The workbed supports your material up to 0.59 inches (15 mm) thick
while allowing effective airflow. It can also be removed to fit thicker
materials or to use the rotary axes. There are vertical and horizontal
inch and cm rulers on opposite sides of the bed.
