If the system normally works as expected and the contour is accurate it would appear the problem is with the file. Cutters follow the instructions received they can't decide on their own to cut 1mm away from the origin point.
I would test with a new file just to make sure all is well, then using the original image and new text using a different font and test again....if all is well at this point, create the file again with the correct image, text and using the correct font.
Seems a strange issue but we had a problem years ago where a customer was unable to cut his name, when 2 characters in a certain font were used together it created a bizarre cut problem, the font had never shown any probs previously.
