Working Distance
The working distance (WD) of the PLH3D-XT-50 laser head should be set to 60 mm
(2.36 inch) between the bottom face of the laser head and the material processed as
shown below.
Working Distance Calibration
The working distance of the XT-50 laser head should be calibrated with high precision
once the initial working distance of 60 mm is set. This only is required to be done once,
unless the laser head was unassembled from the CNC machine and put back on.
An example of calibration (with an XF+ laser head) is shown in this video:

The process consists of engraving lines on the material at different working heights
around the standard working distance. This is followed by moving the working distance
to a height at which the engraved lines are the thinnest.
