Heidenhain tnc426pb drilling chip breaking with pilot hole and gun drilling

[harunV2DKQ]

Hello,

I have a Mikron VCP 1000 TNC 426PB.

I using basic post processor tnc 426 from library
In the attached SS nc code, when I select chip breaking and gun drilling, an error appears = 17 cycl def, if I create new same cycle it in control it works but nc code is identical.
Second, I should arrange the post processor to use chip breaking with a lower RPM approach and feed into the pilot hole, after which the chip breaking cycle should begin.

how could you solve it?

Thanks in advance
