Problems with Sinumerik 808D post, drilling operation, always one hole missing

[apsTWRDF]

Hello,

I set up a drilling operation today and even that the simulation went flawless, in the generated code was a hole missing. 

Here is a quick test piece  to show the result,  it seems to happen all the time.

My machine is a 3-axis mill using Sinumerik 808D Advanced controller.

I added the pictures, code and files. 

Thanks for your help,

Jochen

Hi @apsTWRDF 

Thanks for raising your concern via Forum.

Open post file in a 'Visual Studio Code' or 'Notepad++' to do the required modifications

1. Search ' function onCyclePoint(x, y, z) '

2. Put ' // ' in front of below expression. 

// if (isFirstCyclePoint() && !expandCurrentCycle) {
 //   return;
 // }

Try at your end and let me know the feedback.
