I almost stand corrected ...
Making it a bit more clever it turned out 11 paths for the coarser ... and the finer grid.
Only 1 over the 'probably not reachable limit'.
A bit slower too is the disadvantage.
Conventional or climb milling can not be specified.
- Starting leftwards along a horizontal edge, it may end in the left or in the right direction at any opposed horizontal edge.
- Because it searches downwards it is somehow downwards at the leftmost and also at rightmost edges.
- Then somehow upwards for searching upwards ... Reaching the end of a path downwards it is of no use to start looking upwards.
The milling method of choice is more for the finishing pass(es) at 1/2 tool diameter offsets to the pocket edges.
