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 interruptors, 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.


These microswitches have three connectors
1 = com = wire to signal on your electronics
2 = normally closed (NC) = wire to ground on you electronics
3 = normally open = not required


Socket of Endstop: put the limit switch here.
If you use the photoelectric switch of electric line 3 which we ration you, direct connected is available.
If you use the limit switch of electric line 4 which we ration you, the pins must meet the following requirements:
2 pins in the middle both are GNE, you can choose either one of it.
