Focus Test

Generate a calibration pattern that varies Z height across a sweep. Find your machine's true focus point.

The Focus Test draws a series of test lines at different Z heights so you can find the one with the sharpest cut or darkest engraving. Essential calibration for any machine with controllable Z.

When it opens

Menu: Machine → Quality Tests → Focus Test. Opens inside the Quality Test Shell wrapper.

Fields

Field	Type	Notes
Z min	mm	Lowest Z in the sweep.
Z max	mm	Highest Z.
Speed	mm/min, min 1	Speed for each test line.
Power	%, 0–100	Laser power.
Samples	number, 1–50	How many Z heights to test between min and max.
Z Mode	select	Material (relative to material surface) or Current Z (relative to current head Z).
Line Length	mm, min 1	Length of each test line.
Step Spacing	mm, min 0.5	Vertical spacing between test lines on the test pattern.
Perforated Labels	toggle	Engrave a tick / number per line so you can read off the best Z.
Material Height	mm	Only shown when Z Mode is AbsoluteWorkCoord equivalent. The material surface height for reference.

Buttons

Embedded inside Quality Test Shell: Preview and Run options that gate on the current state.

Workflow

Load a piece of scrap material.
Set the Z sweep range tight enough to find the focus point clearly.
Preview to verify the pattern fits the material.
Run.
Inspect the result, the sharpest / darkest line is your focus height. Note the Z offset.
Update your machine profile.
