The location for a pre-drill point is set automatically, but you can override it for a Spiral type toolpath using the
Plunge point(s) operation attribute.
Note: A
Pre-drill operation is not available with a
Zigzag stepover toolpath.
Note: Zigzag ramping is automatically disabled when you use a
Pre-drill operation with an NT style toolpath. This is not supported for the Spiral toolpath and you must set the
Max. ramp angle to
0 to disable zigzag ramping when using a Pre-drill operation.
Note: The
Pre-drill operation for the NT style toolpaths includes the tops of multi-height islands. This is not supported for the original Spiral and Zigzag stepover toolpaths.
