I think you need to put the G97 s1300 before the g70 line.

the way it is now it sees the g70, runs the finish cycle then it sees the g97.

Put the G70 speed in the P01 block and you can also change to a finishing feed.

don`t you misunderstand the G50 and G96/G97 codes ?
you put G96 S1700 which is 1700 meters per minute cutting speed( this is too much even for alu ) and put G50 S300 which is mean maximum RPM is 300 .
Try to simulate this :

G54:
G0 X200.Z150;
G50 S1700;
G96 S300 M3
T0101 M06
X45. Z3.;
G94 X-2. Z3. F.25 M08;
Z2.;
Z1.;
Z0.;
G0 X42. Z1.;
G71 P01 D1.5 Q05 W.1 F.35
N01 G0 X30.6 ;
N02 G01 Z0. ;
N03 G03 X32.7 Z-1. R1. ;
N04 G01 Z-108.1 ;
N05 G02 X35.9 Z-112.2 R15. ;
G50 S1300
G70 P01 Q05  F.19 ;
