Focus Length and Gcode generation:
The J-Tech diode has a focus length of around 3" from the factory. When setting the work piece home
use a tape measure or calipers to ensure the diode is this distance away from the work piece. Set this as
your Z=0.
When producing gcode for laser use, use a very small Z depth of cut (DoC) such as .001 units. Also,
clearance height can be reduced to 0 for maximum efficiency.
The number one mistake we make here is forgetting to turn the machine back to router mode. After
laser operations recall to set $32=0.
