What do you need?
- Breadboard or proto board
- Generic Optoisolator, I’ve used an 4N35
- A Led
- A resistor
- Some wires
- Shrink tubes
- Soldering Iron and solder
- Tweezers and pliers
Once you’ve all the needed parts you have to assembly the board and connect everything together.
Here you’ve the scheme of the connection that I’ve made:
And this is how it looks like after it’s finished and protected with some shrink tube:
The pinout of the circuit is the following:
- WHITE: +12V
- BLUE: Opto Led Cathode
- BLACK: GND
- GREEN: Z-Endstop pin
Plan B: Buy a premade one
For a better result and a flawless installation I’ve also developed a pcb that is currently in production.
If you want one of this assembled or to solder by your self please send me an email through the contact from.
