If gaps along a toolpath are detected, then you have different choices how the tool should pass the gap and pursue machining. These options are:
and
Depending on the size of the gap it is possible to set two different options on whether it is a big or a small gap.
The value in the field "Small Gap Size in % of tool diameter" sets the threshold for small and large gaps along a toolpath segment. The value is defined as the percentage of tool diameter. All gaps along toolpath segment, which are smaller than this threshold value, are considered as small gaps and the action defined for small gaps is executed. All other gaps that are larger than this value are larger gaps and the action defined for large gaps is performed.
E.g. if tool diameter is 20mm and the gap size is set to %10, then the threshold is %10 of 20mm, which is 2mm. All gaps which are smaller than 2mm are considered as small gaps. All gaps greater than 2mm are considered large gaps.
If you don’t want the gap size depending on the tool diameter just activate "as value" and set a value.
Here you can see that if the motion is bigger than the gap size the toolpath is set to "broken". If the motion is smaller than the gap size the tool movement is "direct". The gap size is set to 50 % of tool diameter. The tool diameter is 20 mm so the small gaps are 10 mm and the big gaps are all gaps bigger than 10 mm.
Additional to the retract strategy you can set:

Use Exit macro
Use Entry and exit macro.
