I have a problem with tool radius compensation in circular moves in the Fanuc type post-processing. I want to have this nc output

G3G41D01G3X158.5976Y98.1114I2.0985J-5.9932

but when I modify the post-processor and add the tool radius compensation I receive an error.
Error received in do_event. Event Handler (in this place postbuilder is given me a path to the post processor tcl file), Event name: MOM_circular_move.
I tried to use any other FANUC post processor from siemens ftp database, but all these posts don't have this implemented.
Someone can help?

This is the same problem as bcl001 wrote couple post down, but the solution doesn't work for circular move.
 
Do you have it set to force the output?
Is it set to optional?

Making it not optional will usually crash the post. Play with those "right click" options.... see what you get.

Also, I have never in my life seen a fanuc that will take a G41 on a G03 line. Are you sure you want to do that?

Jaydenn,

My mistake. I want to D in liner move but as a start to circular move. You are right. G41 in G03 move will be an error on nc execution. I will try, what you said.
 
Jaydenn,

Maybe you know how to force appearance od D after G41 or G42 is called in linear move? I try this what you proposed to bcl001, but it doesn't work in my post. What can be wrong?
 
You said to him to put custom command force once G, but bcl001 wrote he put the command force once D.
 
It is "Force Once G_cutcom X Y D"

Did you see the picture I posted? I'll include it again.

"G_cutcom" is the command that outputs the "G41" or "G42"

the "X" "Y" "D" will force the output of those axis.

Pay attention to the status of "optional" in the "event:linear move"(the little red circles...)
