strange Z shift

Hi there,

I am trying to get my printer working and noticed a strange thing in slicer logs:
2018/12/10 23:10:48.973252 {"Layer":"34","module":"STL","level":"Notice","msg":"Rendering Layers"}
2018/12/10 23:10:48.977697 {"Layer":"34","module":"STL","level":"Notice","msg":"Extracting Layer 1 - Z Level 0.008333334"}
2018/12/10 23:10:49.347765 {"Layer":"34","module":"STL","level":"Notice","msg":"Extracting Layer 2 - Z Level 0.058333334"}
2018/12/10 23:10:49.713430 {"Layer":"34","module":"STL","level":"Notice","msg":"Extracting Layer 3 - Z Level 0.108333334"}
2018/12/10 23:10:50.129781 {"Layer":"34","module":"STL","level":"Notice","msg":"Extracting Layer 4 - Z Level 0.15833333"}



Pay attention at Z levels:
0.008333334
0.058333334
0.108333334
0.15833333

Layers go with 0.05 step which is what I requested. But why it does not start from 0? What is the strange offset 0.008333334? Is this intended?

Re: strange Z shift

Yes it is intended as exact zero layer will cause issue. On the latest builds slicer strategy has changes so numbers will be different
