Delete distance-to-go (axis-specific) / spindle reset
Special cases, "Delete distance-to-go (axis-specific)"
errors, ....
After the axes have been stopped with "Delete distance-to-go" the next program block is prepared
with the new positions. The axes thus follow a different contour to the one originally defined in the
part program after a "Delete distance-to-go".
If G90 is programmed in the block after "Delete distance-to-go" it is at least possible to approach the
programmed absolute position. On the other hand, with G91, the position originally defined in the part
program is no longer reached in the following block.
