The mechanical endstop uses a lever switch to detect when it is activated. The switch is wired up so that when activated, it pulls the signal to LOW. There is also an LED on the board that will light up when the switch is activated. It uses a standard 4 pin 100" pitch header and accepts a standard, old-style CD-ROM audio connector cable.
Mechanical switches are less complicated to implement and cheaper than optical endstops, the function of endstops are to determine the original position of the extruder hot end, so it knows where to extrude the plastic material.
We not just sell them, we also provide professional after-sales service, so welcome to discuss with us, we will try to do technical support as much as we can.
