This worked for me-- Hope it works for you. I'm using SignCutX2 V2.18 on a Redine MH721
click on the hammer and screwdriver button at the top tool bar. Select the "Use external corner registration marks" box.
This is the last thing that is cut (in my deigns it works that way..) and the last registration mark is right next to the origin- so there is no design to be cut between the last cut and the origin.( and if you have the "Weeding Box" checked, it also seems to make it cut that as well)
It's a work-around, not a fix-- but it works.
