NX post, Millturn, Caxis

[Mason321]

getting seemingly wonky code using supplied "cam_sample_mill_turn.prt" and the included, but slightly modded, "millturn_baxis_5axis" post.
The three last DRILL_METHOD operations post as follows:
N0010 G40 G17 G90
N0020 (Start of X head)
(MILL MILL MILL)
G0 C0.0
G0 X5000 Z400
MT=1303
M321
MT=1403
G0 Y0.0 Z4.175 BA=-90. C-270. S2500 M13
G43 X-1.25 H13
G182 X-.9639 R-1.25 F6.
G180
.
^^^^^^^^
why only one hole (Should be 4) and why drilling through the part instead of rotating? The post debugger is showing some errors for the other holes, but i have no idea what to do with it's info.


4 axis Millturn post seems to output as expected with a hole at each C rotation

It's hard for me to tell with what was provided, but it seems like the post could be sensing the drill in the wrong axis or your not outputting in polar coordinates or something else

thanks for the reply
FYI: all 3 files mentioned are out of the box, so it should be easy to replicate this issue; open the part file, post (5ax) and post (4ax). not sure what to show to make it more obvious.

so my question is how to get the 5ax post to output like the 4 axis, for the last drill op in supplied file.

TIA
