File extension for Fanuc 21 T

[Desertrunner]

I have just brought a Lathe build in 1999 and it has aa Fanuc 21 T controller, my question is what would the file extensions being as I am confused. Is it "nc1" or "nc0" or something different.

I have tried to run one of the example given in the manual on the program Cutviwer but it doesn't make the tapper as the diagram shows.
Here is the code.

N010 G50 X220.0 Z190.0 ;
N011 G00 X176.0 Z132.0 ;
N012 G72 W7.0 R1.0 ;
N013 G72 P014 Q019 U4.0 W2.0 F0.3 S550 ;
N014 G00 Z58.0 S700 ;
N015 G01 X120.0 V12.0 F0.15 ;
N016 W10.0 ;
N017 X80.0 W10.0 ;
N018 W20.0 ;
N019 X36.0 W22.0 ;
N020 G70 P014 Q019 ;


The sloping line from x40 z160 to x50 z120 doesn't end up sloping just straight.

The Fanuc doesn't care what the file extension is. On your PC it may be TESTPART.NC or TESTPART.COD or anything else. It MUST be a text file, so it could even have a .TXT extension. In the control it's saved as Onnnn (letter O followed by up to 4 digits).

I'm not sure why N015 has V12.0 this is usually an incremental Y command. Should this have been W12.0?

"The sloping line from x40 z160 to x50 z120 doesn't end up sloping just straight." I don't see this move anywhere. What am I missing?

You are right I miss typed it it should have been "W" not V.
Cut viewer has the code slightly different but cuts the same part dimensions, its code is this,

(TOOL/STANDARD,5,80,0.1,15,3,0,0)
(from/190,110)
(stock/130,160,0,-130)
N010 G50 X220. Z190.
N011 G00 X176. Z132.
N012 G72 W7. R1.
N013 G72 P14 Q19 U4. W2. F0.3 S550.
N014 G00 Z58. F0.15 S700.
N015 G01 X120. W12.
N016 W10.
N017 X80. W10.
N018 W20.
N019 X36. W22 .
N020 G70 P14 Q19 U2. W1.
N022 G70 P14 Q19
N023 M02

Which is not that different.

Its no big deal just frustrating, the Funac book is complex to dumies like me.

What did you expect it to look like? My software shows it like this:

Thanks I think the issue is I am using cutviewer,
What software are you using?

[txcncman]

I used NC_Code Analyzer. Maybe Cutviewer does not handle the W's properly.
