Start and End Codes

Yes is the default.

Yes will give you the safety blocks in the beginning and at the end of the program. It will also provide the tool calls for each cut. Setting this feature to No will not provide any safety blocks or tool changes, but just the XYZ motions of the cut.

For example, all of the cycles to be cut by the same spindles at the same time can be grouped into a Sequence without Start and End Codes (by selecting No). Each group of Sequences can then be grouped again into a final Sequence with Start and End codes.

Here is the code for a sequence with Start and End Codes set to NO:

Here is the same tool path with the Start and End Codes set to YES. The code in red is what Start and End Code added to the program.
