So those area scanners on the floor have zones that should be mapped out. You have to download the software and plug into them, but then your able to set sensitivity (which might be the problem if only happens when it is cutting), range, where it should mute, etc...
OK! I think the chips are indeed setting off the area scanners. I am surprised something that small sets it off but I guess when there are a lot of them the scanner reads it as a larger object. I will download the software this morning and try out some different settings. If the chips continue to pose a problem we will have to look at different safety measures than these scanners.
