1pc Emergency Stop Switch + 10pcs Limit Switches For DIY CNC Kit
This kit can be used for a DIY CNC kit which can protect the machine during operation.
Emergency stop switch can result in a complete stop for all of components. When the E-stop switch is pressed, the breakout board sends a signal back to the software and the software will stop all devices like stepper motors, spindle motor, router, etc..
Limit switches tell computer the limit position of the CNC machine. When one of the axes moves to an axis limit, the switch is activated and the machine stops. These limit switches are also used to inform the computer of the "Home" position. Typically, 6 of these switches are needed, 2 per axis. The extra 4 switches can be used as spare parts or for limiting the Home position.
