The 3D Ball frame is certainly a very old frame. Perhaps 25 years old... It was made back in the days of moving iron galvanometers, which were generally more robust and more "fault tolerant" than moving magnet scanners. The ball can be displayed by modern projectors, but not likely at "full size", and certainly not faster than 30K almost regardless of the type of scanners you have.
I'll also say (and I hope most people will agree) that I am a scanner expert. When all equipment is functioning 10000000% correctly, nothing should ever blow a fuse. (For example, there should be nothing that the user can do that will cause their hard drive to catch on fire.) And so your report tells me that *something* within your greater system isn't functioning correctly.
And finally, I will say (and again, I hope most people will agree) that I am somewhat of an expert on Cambridge scanners, and with that being said, Cambridge actually doesn't even make "45,000 galvos", nor anything even remotely having that kind of name. For that reason, I will make the broad assumption that you have been *sold* something (hey, buy this projector because it has Cambridge 45,000 scanners), but the reality is that you probably have Cambridge model 6210 scanners (which are nominally 30K scanners, but will go faster under certain circumstances), but I assume that (unfortunately) your 6210 scanners are driven by something other than Cambridge servo drivers. Personally, knowing nothing more about the situation, I am making the assumption (which I think everyone will agree is dangerous) that your driver is not really functioning 100000000% correctly, didn't have the right fuse, didn't have the correct "coil temperature calculator" settings, or the like, and THAT'S why the fuse blew.
LD2000 is our older-generation software. Since the release of that software more than 16 years ago, our development strategies have become a lot more defensive... Basically this means that we've stopped trusting that projector manufacturers will build projectors that are 1000000000% robust... For that reason what you experienced would not have been possible with QuickShow or BEYOND, even having a projector with drive electronics that were not functioning correctly. Nevertheless, our position is that YOU have done northing wrong. It is the equipment which let you down... (Again -- hard drives never catch fire, regardless of what whacky things computer users do...)
I think the best solution to the problem that you have experienced, and more, would be to engage in a training session to learn how to use the software better. Such training would allow you to more fully understand the limitations of laser projectors and of the software, as well as giving you a good background on making laser shows. We tend to offer public training sessions once per year (usually taking place near tradeshows) and also arrange private trainings at our office from time to time.
