in NF. If you program Q = 1 (Continue from last text) tool change
and pre-positioning are suppressed. The technological data of the
previous engraving cycle apply.

Position form:
Z: Start point
C: Start. angle
CY: Start point first character
X: Final point – X position, infeed depth during milling (diameter
value)

W: Inclinat. ang. of the character string
FZ: Plunging feed rate factor (plunging feed rate = current feed
rate * FZ)
D: Reference diameter
Q: Continue from last text
0 (No): Engraving starts at the starting point
1 (Yes): Engraving starts at the tool position
