Limit Switches
I'm retrofitting a CNC and need to know how to select limit switches that are compatible with my Buildbotics controller. Some indicate that they work with Arduino, some don't say.
Re: Limit Switches
Any limit switch that provides a contact closure will do the trick. The limit switch inputs on the Buildbotics Controller are just TTL compatible gates that are pulled high to 3.3Volts. The switch contacts just connect that output to ground.
I like the magnetic proximity sensors like these

They come in two parts. If you buy them make sure you get both parts
