Shallow area machining detects shallow areas on the model and inserts additional stepdowns to provide a better finish of the shallow areas.
The shallow area settings
When enabled, the shallow area machining is controlled by two parameters:
Minimum shallow stepdown:
This parameter controls the minimum allowed stepdown between the extra Z-levels and takes precedence over the maximum shallow stepover.
Maximum shallow stepover:
This parameter controls the stepover used to detect areas where extra Z-levels should be inserted. If the normal stepdown results in a stepover of more than this value, extra levels are inserted until the stepover or the minimum stepdown is reached.
