I have much the same issue with a Tronxy X5S & Wanhao Duplicator i3. I have not changed any of the settings from a prior use that worked and now I can no longer slice a model. I ran the same model in another slicer and it worked fine so it is not the model. I select the model hit slice and the program shows it is slicing but does not advance. It is a small model which I have printed prior in cura with no problems
