Direct selection/deselection (G239) of TRC without a block

With selected G239 the TRC start-up motion is identical to G138 (directly).

The deselection is done on G40. The TRC is deselected by overtaking the coordinates of the last equidistant point as the latest current position. A following motion block for reducing the tool radius distance is not required.
