ZStart value

Field for drilling and pockets

This field can contain a fixed value or an instruction. Applies to the machining functions:-

Horizontal drill

Universal drill

Pocket

For horizontal and universal drill instructions, the 'Position in Z field' is no longer available as a tooling field and is replaced by the ZStart value.  The 'Position in Z' field is still available for End groove instructions.

This is the value of the co-ordinate in the Z direction.

Notes

The program automatically converts data from a previous version to the new format.

Initially the Z1 value is use for the ZStart field, then the Z value, and finally =Z/2.
