Our Summa died and while we are awaiting parts I picked up a used Graphtec FC8000-160 to keep us running. It's connected via serial port. We can cut from Flexi perfectly fine. The issue is with trying to print and cut from Onyx. Most files, when we send the cut file it doesn't try to read the registration marks. It just starts cutting and of course isn't registered properly. The weird thing is some, at least 2 have worked perfectly fine. I've tried those files several times and every time it looks for the marks then will cut. Other files it goes right to cutting. We are using the same settings in Onyx and on the plotter. I don't know what we could be doing wrong and why it isn't try to read the registration marks before cutting when we send the file from Onyx Cut Server. Any ideas?
