Cross wire C-CW
This useful item allows you to align the laser beam. It is a thread insert with a pair of copper wires and
can therefore be screwed in at any location between parts to check for a central beam. Once the beam
is aligned, replace it with a normal thread insert.
A quick beam burn on card or viewing the beam on a mode plate will show the silhouette of the wires.
Make adjustments until the silhouette cross is central to the beam. You need to check the alignment a
various places, working your way from the laser to the work piece.
Any odd mode pattern may indicate that the beam is reflecting off the inside of a pipe or is being clipped
