Note
If you do not enter a D number, you will be working without a tool offset.
Machine manufacturer
Machine manufacturer default setting (e.g., D1, which means no D programming) is
activated/selected by means of tool change (M06) D1. The tools are activated with T
programming (see machine manufacturer's specifications).
The offset is applied with the first programmed traverse of the respective length offset axis.
Caution
The modified values only become active the next time the T or D number is programmed.
The required D number must always be programmed before the tool length offset can be
selected. The tool length offset is also effective if set in the machine data.
