Hi Fraser,
I own the whole set: Faxitron MX-20, EZ240 -> flatbed scanner, power supply, ribbon cables, PCI card and software. The PITA is the 35kV generated by the MX-20. Not powerful enough to analyse some serious latest gen multi-layer boards. With regards to the camera focus, I think your theory is correct; probably the camera focus is optimised for objects located at circa 1m away from the source. Adjusting the focus shall probably give out better results.
re:”EZ240 inside TR15” my only worry would be how to pass the ribbon cables out the main chamber. One ribbon cable is used for data transfer whilst the other for power which is connected to an external power source. The TR15 door is quite tight so I either risk damaging the cables or creating a leak which I honestly wouldn’t want. If you have any ideas let me know.
Even if this problem is solved, another one would be to adjust exposure time so that the scanner has time to scan the area. Current time is set to roughly 6 seconds. However, this can solved by installing a small application controlled via ethernet which would send serial commands directly to the XRAY board modifying exposure time. A quick look at your pics suggest communication protocol is serial over USB. But I might be wrong.
I literally got the TR15 last week. I only did a couple of tests with it. I am going to wait for a Todd engineer to come over and check it out first. Just making sure it doesn’t have any leaks and it’s safe to use.
