I just inherited a Romer Arm from a sister company that bought it in 2017. They never used it since the classes, so we now have it to put it to use. It's an Absolute Arm 7 axis 7525 SE with an external HP-L-20.8 Laser Scanning System.
I'm not counting on getting sent to classes, so I may have a "few" questions as I try to make this thing useful.
The absolute scanner does not work well on shiny surfaces. You can try scanning in a darkened room to see if that helps. The best thing to do is use a dusting spray to take away the reflection. We use the white dust used for penetrant testing, and that works very well.
