For 3D Printers, the BLTouch is the gold standard bed sensor. The knockoffs coming from China are looking so close to the original I though I would test one of them out. Can the original really be worth four times as much money?

To everyone who says I didn't connect the wires correctly: I did. I hacked on this sensor and got it working, but I'm not about to show you guys how to spend a couple of hours of your life to get a stolen design working. Support original creators. Buy genuine.
