Hi guys.
I'm trying to run this program:

N10 G20;
N20 T0101;
N30 G97 G95;
N40 G50 S3600;
N50 G96 S960 M03;
(ROUGH FACE OFF)
N60 G00 X1.6 Z.050;
N70 M08;
N80 G00 Z.00;
N90 G01 X.00 F.030;
N100 G00 X1.60 Z.050;
N110 G00 X0.0
(TURN TO DIA.)
N120 G71 U.050 R.100;
N130 G71 P140 Q190 U.050 W.050 F.020;
N140 G01 X0.0 Z0.0;
N150 G01 X0.5 Z0.0 F.030;
N160 G3 X.750 Z-.125 R.125;
N170 G01 X.750 Z-.480 F.030;
N180 G2 X1.25 Z-1.187 R1.125;
N190 G01 X1.25 Z-1.60 F.030;
(CHAMFER CUT FOR RADIUS)
N200 G00 X1.6 Z.050;
N210 G00 X.660 Z0.0;
N220 G01 X.750 Z-.045 F.030;
N230 G00 X1.60 Z.050;
(FINISH PROFILE)
N240 G00 X00 Z.050;
N250 G70 P140 Q190 F.030 S960;
N260 G00 X1.60 Z.050;
N270 M9;
N290 M30;


When it gets to line N130 (where G71 starts) it wants to cut the full depth instead of .050 as specified in N120 U.050. Peter Smids book v3 pg 326-327 has an unclear example.

I've tried a couple things to no avail. What am I missing?
Thanks guys.

Quick fix listed below.

N100 G00 X1.60 Z.050;
N110 G00 X0.0................. (Remove this line)
(TURN TO DIA.)
N120 G71 U.050 R.100;
N130 G71 P140 Q190 U.050 W.050 F.020;
N140 G01 X0.0 .........(Remove this....Z0.0) ;
N141(Add "Z0.0 here);
N150 G01 X0.5 Z0.0 F.030;
N160 G3 X.750 Z-.125 R.125;
