Files edited with latest Illustrator have problems cutting on cutting tables such as Zund , Esko...

Helllo , 

we would like to share a problem we have been experiencing for some time. We design and manufacture cardboard packaging boxes. We design the boxes in Engview, and then we prepare them for prepress in Illustrator. We use Zund G3, iEcho 1047, and Konsberg C cutting tables to cut samples and check the designs. The problem is that files edited in Illustrator do not cut correctly. They experience twisting, distortion, and displacement of creases relative to the cutting contour. Here is a list of tests we have conducted to draw conclusions and potentially diagnose the issue:

- Files generated by Engview cut normally, but after editing and saving in Illustrator, problems occur.
- Files saved in CS6 version cut normally on ZUND, but when converted to DXF for the iEcho cutting table, they do not execute correctly.
- Files edited with the latest versions of Illustrator do not cut successfully on any of the cutting tables.
- Files edited with Illustrator and converted to DXF do not cut correctly on iEcho 1047.
- All files are visualized correctly in all software (EngView, Illustrator, Zund CutCenter, IbrightCut Center, i-- cut Production Console).
Formats tested: PDF, EPS, AI, DXF.

We think that this problem occured sometime in the past 6-9 months probably. We didn't have any issues cutting on Zund before that, or it was a rare problem and we didn't notice.
