The machine will shut down and will be "hard" to turn back on (Require that the fault is cleared, etc.)
However, the problem is: if you are machining aluminum, it would automatically trigger, meaning that you would need to measure resistance. I do not see how the SawStop works with metals!

The SawStop does not work with metals, nor Carbon Fiber. As mentioned there is a way to temporarily disable it. I've had to change a couple of cartridges from people attempting to use it for those materials.

The number of teeth that is optimum depends on the metal and the thickness of the metal. The harder the metal (steel) the more teeth, the thicker the material the lower the number of teeth.
