Sawstop is a great invention but has known to false trigger and you then need to replace the blade and the gas cartridge. I believe wet wood is an issue.
If you use a Sawstop you should know what can cause it to trigger and not use those materials. Let your wood dry before cutting and never use something with foil on it.
Such as slightly damp wood (think portable jobsite saw for framers or finish carpenters) or aluminium (yep, you can easily cut aluminium with most wood working tools).
