10.7 Repetition of selected G function (G41, G42) with same offset
number
If a G41/G42 function which has already been programmed is repeated, a vector with length R
and perpendicular to the programmed path is created in the preceding block at the block end
position.
The block start intersection is calculated for the following block:
N20 G91 D10 G41 X . . . Z . . .
L F
N25 X . . .
L F
N30 Z . . .
L F
N35 G41 X . . . Z . . .
L F
N40 Z . . .
Error! G41 repeated in N35.
