Mine is set up the same way as Gary, power is normally off to the laser unless I am about to use it. My system is wired up so I select between power to the router or the laser, you can’t accidentally have both on. I have the reset button wired up to a button on the front of my table. It’s a lighted arcade button, the light is hooked up to the laser fan power so it glows red when the laser has power. There is about a 2 second delay for the power supply/driver to be ready for the reset button to be pressed, I think that is from the power supply charging up. Details of the setup are here:
And to answer the original question, I have my laser driver board mounted under the table my XXL is on. Keeps dust away from it and saves me a couple of inches of clearance on the side. The under table setup would be really inconvenient without the remote power and reset controls. The couple of inches saved on the side were useful to have when I built an enclosure later. The sides get a bit tight. The enclosure is nice for the laser, no more wearing glasses for my wife and I while the laser is doing it’s thing (often for long periods). Still need the glasses when doing the initial aiming but that is just a minute or two, and just for me since the back of the enclosure faces my wife’s side of the basement. A few pictures of my enclosure are here:
