So now I am curious if there are different brake systems that are more accurate than a wingnut hitting a switch since I have batteries available. I could not find any online resources showing any. I was thinking of something like a photogate system that shuts off circuit when wingnut passes by and cuts through light path... but not sure if this would work.
Anybody experiment with other brake systems?

"batteries, wires, motors, switches, resistors, potentiometers & mechanical relays.". I personally think that wing nut is the most accurate in our constraints, just make sure that the switch is activated at the same time as the brakes. Last year for scrambler, my partner and I got to the nearest half millimeter in comp with the wing nut system.

With the popularity of 3D printers, it's possible to find equipment like this in a variety of sizes. I'm wondering if there's any advantage in precision over a traditional hardware store wingnut/threaded axle system
