-CNC 3D Printer Mech Endstop Switch 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.
-The mechanical endstop is a simple solution to a simple problem.
-We want to be able to detect when an X/Y/Z stage has reached its minimum or maximum.
-Instead of messing with flags or complicated light beam interruption, we use a mechanical switch.
-If we place the switch in the path of the stage, then the stage itself will simply close the switch when it moves against it.
-Other than properly positioning the switch, we do not need to modify the stage at all.
-If you’re worried about reliability, you can sleep well at night.
-The switches we use are rated for 1 million operations before failure.
-Since we only use the switches once per print, that means you’ll be able to do one million prints before having to replace the switch
Connection description:
Redline : connecting VCC (ramps of +)
Black line : connecting GND (ramps of -)
Green Line : connecting SIGNAL (ramps in s)
