Multiple threads with G33

Syntax G33 X.. Z.. F.. Q.. is used to program multiple threads in ISO dialect T and
M mode, whereby:
X.. Z..
F..
Q..
Threads with offset slides are programmed by entering starting points, which are
offset from one another, in set G33. The starting point offset is entered at address
"Q" as an absolute angular position. The corresponding setting data
($SD_THREAD_START_ANGLE) is changed accordingly.
Example:
The initial angle must always be programmed as an integer value. The input
resolution for angular data is 0.001 degrees.
Example:
4-130
