Peck drill problem!?

Hello everyone,
I have a issue, when i am drilling deep hole a peck drill does'nt work properly. For example i need to drill 70mm hole , i set in mastercam driling properties to drill a hole with a peck drill with 5mm (so it has to drill a hole in to -70mm with retracts of 5mm from stock . But when i start the program in the machine first peck is 10mm and the rest peck drill's are 15mm till it reach - 70mm , but i need that retracts will be 5mm not 15mm. I hope you guys will understand what i need my english is not so good.
Waiting for quiq respond. Thank you for any information.

My Milling machine is Chiron Fz 33 with Bosch system.

Upload a file / zip to go so we can see the issues.
If there is an issue with the code, most likely need to edit the .pst

What file i need to upload my post processor? or the generated code file of my program?

More I information the better.
A mastercam file with your drill settings. Pst if your Happy to share. Sample code for machine. One straight from mastercam and one edited to how you want it to be.

Your attachments are not there

The NC code is good foe Fanuc control, it does a "full retract" back to the R-plane after each 5mm peck

Nothing in the NC code give rise to your 1st post problem, are you sure it's not a parameter setting on the machine control that controls the "peck clearance" ( the parameter may be set to 10mm, normally should be around 0.2mm - 0.5mm )

i quess its a paramter but maybe there is a problem becouse i write program with mpfan pots proccesor wich is for fanuc system but our cnc machine has bosh system

I agree the code looks fine, only thing I would suggest is to change the initial height to something different to R plane as use of M99 might confuse machine. But shouldn't. ???
Best place to look is in the machine manual.

So, why are you using a Fanuc post on a Bosch control ?
- post are created & modified to eliminate editing the NC file

i dont have pots for bosch system thats why i am ussing fanuc pots i think its very similar to fanuc most functions works fine. i modifyfied this pots proccesor just one problem with that peck drill. Our machine chiron fz 33 its very old 1984 y. i even couldn't find manual of this machine

Hello,
Before i everyting worked fine but today i got a problem when i tapping a hole for example i need to tap M4 hole into -10 i set feed rate 105 and spindle speed 150 . The spindle goes clokwise into -10 and then starts spining diferent way but feed rate changes and dont lock to 105spining speed and it should retract but it stays in same position -10 but after one minute feed rate changes to 105 and normaly starts to retract.

Its dificult to explain maybe some one will understand the problem

Until you show us the code that you have created & used
- & the code that the Bosch needs, you need to edit the Fanuc NC code to prove it works in your machine.....

The other thing to add is what your program format must be
or
what needs to be set before running certain code......( read your manual )

ie G99 G84 Xxx Yyy Zzz Rrr Ppp Fff
where:-
G99= return to R-plane at end of each cycle
G84= Right Hand Tapping cycle
XY= absolute position of the hole from part origin
Z = Hole depth relative to part origin
R = Retract plane at the cycle end ( G99 active )
P = Dwell (time in seconds)
F = Feed (units per revolution (if G95 is active ), or units per minute( if G94 is active ) )

Never assume that NC code for one machine type will run in another control
