    Joe,
    Many of us use flash drives to transfer toolpath files from a designated design computer to a designated router computer. That makes the flash drive like a piece of tooling. Many of us...

    The only problem I can see (and I may not be understanding you correctly) is how you would get the plugs in place. Most vacuum tables have the plenum cut in a sheet and then a bleeder placed overtop...

    stephen,
    They are wired backwards. They should not be on (glowing) all the time. Only when they are near something. Your bot thinks it is at its limits all the time.
