Do you cut direct from Illustrator, or are you exporting it to another program?
I sometimes have a similar problem when I send an Illustrator file to SignLab. SignLab will import .ai files and that is when the problem usually occurs.
I have found that the problem disappears if I export the .ai file to a .dxf file, and then import that .dxf file into SignLab.
Try converting your text to curves and then making it a .dxf file and see if that helps the problem.
If you can't cut a .dxf file, then just convert text to curves and try cutting the .ai file.
