Laser Path Calibration
Although our factory calibrates your entire system during assembly, it is possible for the laser tube, the focus lens,
and/or one or more of the mirrors to be jostled out of alignment during shipment. As such, it is recommended that you
perform a full optical alignment test as part of setting up your machine. See §6.4 in the Maintenance section below
for step-by-step guidance.
