11. D word on line with no cutter comp on (G41 or G42) command
12. Tool radius index too big
13. Tool radius not less than arc radius with cutter
radius comp
14. Two G codes used from same modal group.
For some of these messages additional explanation is given below.
Changing a tool while cutter radius compensation is on is not treated as an
error, although it is unlikely this would be done intentionally. The radius used
when cutter radius compensation was first turned on will continue to be used
until compensation is turned off, even though a new tool is actually being used.
When cutter
radius compensa-
tion is on, it must
be physically
possible for a cir-
cle whose radius
is the half the
