OneCNC to Siemens post processor

Hello everybody. Just signed up to this forum and am after some advice. We have 3 XYZ mills with siemens 828D controls and we have OneCNC RX8 with 4th axis module. The post processor works fine for moving machine around, tool changing etc but it does not seem to post correctly for G code cam cycles. OneCNC say its the siemens control and siemens say it is the post processor with OneCNC. Whether it is a tapping cycle, drilling cycle, boring cycle etc - if you type G83 or G84 in the control it does not recognise it, but siemens swear blind the control accepts G code. Any help would be much appreciated.

Of course sinumerik can read the cycles G goces. But siemens cycles looks completely different than any others. It should be eg. G83(0, , ,0,5,5,5, , ,) the bracket contains parameters that are sorted in particular way so there have to be proper number of places between comas. If the postprocesor generates cycles like for fanuc with parameters set by adress it won't be read by sinumerik.
