G42 2D Cutter Compensation Right Group 07
G42 will select cutter compensation right; that is the tool is moved to the right of the programmed path to
compensate for the size of the tool. A Dnn must also be programmed to select the correct tool size from
compensation memory. If compensation memory contains a negative value for cutter size, cutter compensation
will operate as though G41 was specified.
Refer to the "Cutter Compensation" section for more information.
TOOL L ENGTH C OMPENSATION (G43, G44, G49)
G43 Tool Length Compensation + (plus) Group 08
This code selects tool length compensation in a positive direction. That is; the tool length offsets are added to
the commanded axis positions. A nonzero Hnn must be programmed to select the correct entry from offsets
memory. The automatically entered offsets using the TOOL OFSET MESUR key assume that G43 is being
used.
G44 Tool Length Compensation - (minus) Group 08
This code selects tool length compensation in a negative direction. That is; the tool length offsets are sub-
tracted from the commanded axis positions. A nonzero Hnn must be programmed to select the correct entry
from offsets memory.
G49 G43/G44/G143 Cancel Group 08
This G code cancels tool length compensation. Putting in a H0 will also cancel tool length compensation. G28,
M30, and RESET will also cancel tool length compensation.
ENGRAVING (G47)
G47 Text Engraving Group 00
Will not work with G code 91
E = Plunge rate (units/min)
F = Engraving feed rate (units/min)
I = Angle of rotation (-360. to +360.), default is 0
J = Scaling factor in inches (minimum = 0.001 inches), default is 1.0 inch
P=1 for Sequential Serial Number Engraving
0 for Literal String Engraving
R = Return plane
X = X start of engraving
Y = Y start of engraving
Z = Depth of cut
The text to engrave should be in the form of a comment on the same line as G47, with either a P1 or P0 before
it. P1 selects Sequential Serial Number Engraving and P0 selects Literal String Engraving.
