Cutter Comp must be entered in a G0 or a G1. Cutter Comp
can be entered and exited in the main program and past
to the sub program or entered and exited in the sub program.
The D value must be entered prior to the G41 or G42, But
does not have to be on the same line. Just to clear things
up the D is a register # and not an offset value.
(G41 D5) correct (G41 D.003) Incorrect.
Now if you have done all this correctly and in running the
program you adjust your offset in the Tool offset table
you dont see an imediate chage, here is why.
The Fadal control has a variable in the SETP page that
is look ahead buffer. As I remember the older machines
could be set to 256. If this is the case then the Fadal
control will read the program and buffer many lines ahead
and never UPDATE your diameter offset change UNTIL it
refills the buffer!
So if you have a short program with subs and you make
any offset changes XYZAB or HD it will not see them until
the buffers are refreshed, UNless you stop the program and
restart it. You can use the AU command and start mid program
with success. (USE caution on this as it will move to the
prior XYZ location prior to execution)
Hope this Helps
