Peck drilling on Okuma lb3000 osp200

Have been able to peck drill but can't get drill to retract to face of part.I used G74 z-2.5d.25k.25r.of.oo8
Can anyone help with this.
Check the parm
Set at 500

hy :) if better control is needed, i like to write the code :

Code:

---

    G00 X0 Z2.5
    G01    Z-50      F0.10 G95
          Z-50+0.15
          Z-55
          Z-55+0.15
    G00    Z50                  ( or, if you wish, feed out slower, at smaller clearance G01 Z2.5 F2000 G94 )
    G04    F....                ( maybe dwell a bit ? )
          Z-55+1              ( back in )
    G01    Z-60      F0.085 G95 ( use slower feed for the last 5mm )
          Z-60+0.15
    G00    Z2.5

for deep holes, or when drill flute's are relatively too short, you may use the load diagram, in order to fine-tune your code

if you wish, i may share drilling codes for osp

by the way, there is a nice okuma forum here : https://www.cnczone.com/forums/okuma/

kindly :)
