No worries about your English Greg, it was my answer in half English/half Dutch π. i dont agree with you mate. when i slice the design in Prusa copied it there 3 times, all the 3 items get sliced exactly the same, where ever i put them on the bed or rotate. Ill show you in piccies.
Your repaired file shows an artifact which wasnt there in original, thats odd, it is also cutting corners!
I am sure that my design has no defects, its done in fusion360, a piece sliced from a circle etc etc. the corners are exact same π
I love cura slicer, thats why i would like a developer look into it.
Cya!
