Dynamic Billet - Click to create a continuous entity (the 'dynamic billet') which defines the remaining material on a 2.5D profile. This entity can be selected for a subsequent pass by a smaller tool. If checked, the Contouring tab is not available.
The advantages of using this parameter are:
a much greater proportion of material in tight corner conditions can be removed
the advanced algorithm reduces cusps of uncut material on approaches to the corner.
Engrave - Check to use EdgeCAM's engraving features. If checked, the Contouring tab cannot be used.
EdgeCAM 3.1 Compatible - The Areaclear cycles are created using a different method from EdgeCAM 3.5 onwards. In particular, the Helical/Zigzag approach methods were different. Check this box to use the previous method. If loading an old part, this box is checked by default.
Tolerance - Controls the machining accuracy. Specify the distance band across the width of the mathematically correct toolpath within which the actual toolpath entities can be generated. Small values result in a more accurate finish, but the system takes longer to generate the toolpath. When slotting, if a Continuous entity contains an arc that does not lie in either the XY, XZ or YZ planes, the resultant toolpath will break the arc into a series of small linear moves which lie within this tolerance.
Mid Point Snapping - Check to allow mid-points of entities to be acceptable as start/end positions, as well as the end points.
