BUG REPORT- CAD model looks OK, STL looks OK, CP sliced model not right

Software

This is the first time I’ve seen this happen. Every part of the process comes out OK until I slice the model in CP 7.0.04127.

In fact I sliced the model in CP 5.1 and it worked OK.

I sliced the model in CP 6.2 and it failed.

This is the model in FreeCAD:

The same sliced file in CP 5.1- looks like it should with no problems in the wall:

Have you tried to repair the file ? In the slicer, right click on it and then “repair” :slight_smile: !

That did not work, but what I did find was that if I changed the settings profile, the slicer worked. I narrowed the problem down to the setting Precision\X-Y Contour compensation which was set to 1.0041. I changed this to 0 and it fixed the slice.

I think there is a bug in CP because any value other than 0 causes PART of the model to scale out- not the whole model.

Model attached if anyone can check on their end?
