Confirming A Proximity Sensor Myth

Показать описание
In this video I debunk a myth about proximity sensors.

Here is a link to Tom's Guide Video "Sensor Showdown"

And here is a link for the 5v 8mm sensor:
M18 8mm sensing DC 5V NPN NO LJ18A3-8-Z/BX-5V cylinder inductive proximity sensor switch work voltage 5VDC special for MCU
(from AliExpress Android)
Check out Myth #6. Saying it doesn't make it so.

Toms one of my fave 3d printer youtubers. But hes said some asinine shit before. The bondtech extruder review. Epic face palm. More torque helped me tremendously during my early petg battles. Even prusa knows whats up, thats why they are using them.
