Okuma lathe post L400II-e

Hello guys,

I'm struggling with the post-processor for an Okuma L400 lathe, a standard machine without live tooling. I've modified the peck drilling cycles and regular G1 movements.

The problem is that I cannot switch between feed per minute (G94) and feed per revolution (G95) — no matter what I select in the drilling operation settings or in the tool properties, the post-processor doesn't apply it.

Please help me modify the post-processor so that I can manually control G94 and G95.

Thank you!

This is what I have

(O8861.MIN)
(T03 D=1.25 CR=0. - ZMIN=-3.6677 - DRILL)
N10 G50 S2000
N11 G0 X400.
N12 G0 Z400.

(DRILL1)
N13 T030303
N14 G90 G94 G18
N15 M8
N16 G97 S1500 M3 M42
N17 G0 X0. Z0.65
N18 G17
N19 G0 Z0.25
N20 G1 Z-3.6677 F9.
N21 G0 Z0.25
N22 G180
N23 Z0.65

N24 M9
N25 G0 X400.
N26 G0 Z400.
N27 M2

this is what I want to be able to choose.
