Sorry I have no idea.
Second attempt. Win732 bit and David Basler camera. Pc another WinXP 32 bit and the same version of Mach3.
What does that mean? Win7 or WinXP? Anyway it should be the same with both.
I can only assume that there are some "hiccups" in the mechanics or in the computer system...
We have no experience with Basler cameras. Maybe they cause some trouble?
