ENDER 3: DIY Auto Bed Leveling

Hello, thanks for watching.
In this video we add an ABL system, yes you can buy a kit like https://rb.gy/9kakj4 but that's a lot of money for "support" and I don't like the BLtouch. I used this guide to help assemble this project https://rb.gy/1djpdu
we used
LJC18A3-B-Z/BX Capacitive Proximity Sensor https://rb.gy/apdknc
Optocoupler Isolation Module Isolated Board https://rb.gy/fdox0z
(in video we were going to hard wire it, opted not too so I re-soldered green terminal blocks)
We put this system on two Ender 3, on with an original mainboard & the other with SKR Mini E3. (SKR in video)
In the video we did not show firmware coding, check out Chris at https://rb.gy/2dokwy he much more knowledgable than me.
We also pretty much just got it homing in the video, but off video really calibrated it to work better.
If you want to try this, please do hopefully this helps a little. I have found this very educational and worthwhile experience.
Until the next,
