Incremental Monitor

Fire a keystroke every time a chosen axis moves by a fixed delta. This is the mode to use for time-lapse-by-layer photography.

When to use it

• You want one photo per layer, without telling the slicer anything.
• You want one photo per N millimeters of travel in any axis.
• Your camera setup needs a quiet moment before the shutter — incremental mode has a built-in snap delay.

Options

Axis to Watch — X, Y, or Z. For layer-by-layer time-lapse, pick Z.

Change Amount (mm) — the delta that triggers a match. For a 0.2 mm layer height, set this to 0.2. For every 10 mm of Z travel, set 10.

Poll Interval (seconds) — how often SnapAzule checks the current position. Fractional values are allowed. Lower is more responsive but uses more CPU; 0.5–1.0 is a good default.

Snap Interval (seconds) — how long to wait after a change is detected before firing the keystroke. This gives the printer time to stop moving and the bed time to settle. 2–3 seconds is typical for layer-change photography.

Example: one photo per layer on a 0.2 mm layer height print

Axis:             Z
Change Amount:    0.2
Poll Interval:    0.5
Snap Interval:    2.0

Whenever Z changes by at least 0.2 mm, SnapAzule waits 2 seconds (during which the printer moves to its next layer-start position) and then fires the keystroke.

Notes

• The first match fires once SnapAzule has seen one Change Amount of movement from the position at boot — not from zero.
• Set Snap Interval to 0 to fire immediately, without the settling delay.
