Heads up there is a bug in the latest 10.5.2.1 version of job control. The Z value in the software does not scale linearly like the old version. So if you keep a database of Z values they won't work in 10.5.2.1.
Hopefully this saves you guys the headaches we occurred when we upgraded from 10.4.2 to 10.5.2.1 and encountered this bug. I've reported it to Trotec but if anyone else encounters it please report it as well. The more people that report the bug the faster Austria will fix it. Bug affects my 2 speedy 300s and also our speedy 400 all on different computers. Restoring back to job control 10.4.2 fixes the bug.
