Fanuc post processor problem

[lrl_0048]

Hi all! I have a problem with the Fanuc post processor in Fusion! In the G code, all compensations (G40,G41, G42 and sometimes G43) come out in the following format G01 G40 (G41, G42,G43) X...Y ...; and this, of course, gives an error! It also started giving me an error PS 0034!
Can anyone help me?
Thanks in advance!

Hi!
What is your control and your machine? I've just checked on Fanuc 11M and there is no error.

Could you attach a code and point when exactly (which line) an error pops-up on your machine? If you could share your Fusion File Share Link which contains CAM data, it would also help me find the cause.

I referred to the Fanuc alarm code list, and it states "An attempt was made to perform a start-up or cancel of cutter
compensation or tool nose radius compensation not in the
G00/G01 mode. Modify the program."

FANUC requires that cutter compensation (G41/G42) or tool nose radius compensation be activated or canceled only during linear interpolation (G01) or rapid positioning (G00).If your program tries to turn compensation on/off during an arc move (G02/G03) or any other mode, the control will trigger PS0034.

When your compensation type is set to "In Control", then your linear lead-in distance has to be greater than zero.

Anyway, even when I posted the code after ignoring this warning, still compensation is switched on during linear movement.

My machine is First V700 with Fanuc 0i-MD

N345 X-102.803 Y49.905 Z-1.
N350 G41 X-88.108 Y29.68 D04
N355 G03 X-85.873 Y29.326 R1.6
N360 G01 X-24.744 Y73.738
N365 G03 X-24.104 Y74.783 R1.6
N370 X-24.39 Y75.973 R1.6
N375 G01 G40 X-39.085 Y96.199

That is a part from the program....Here give me Modal blok stop alarm

Do you know what the code should look like? For example:

G01 G40 X-39.085 Y96.199

VS

G40

G01 X-39.085 Y96.199

VS

G40 G01 X-39.085 Y96.199

If so, the post processor needs to be edited, particularly the "onLinear" and/or "onCircular" functions. If not, you may need to adjust the lead-ins/lead-outs. That can be time consuming...went through that with a precision bore...was hard to nail down the lean-in/lead-out parameters when using cutter comp with a large cutter in a tight bore.
