Hall effect sensors are cheaper than reed switches.
Hall effect sensor 3d printer.
They are also lighter than contact probes and need less cabling no need to move the probe in and out of the.
Hall effect sensors are about fifteen cents each reed switches are almost a dollar.

I tried dozens of different hall effect sensors to see which one would work best for the spokepov kit to determine the wheel location and this one came out on top.
A precise bed level is just plain compulsory.
Runs at 3 5v up to 24v.

The end stops are used to calibrate the absolute position of stepp.
To use connect power to pin 1 all the way to the left ground to pin 2 middle and then a 10k pull up resistor from pin 3 to power.
A hall effect sensor is a transducer that varies its output voltage in response to a magnetic field.

Originaly designed to be used on shapeoko cnc routers.
In a hall effect sensor a thin strip of metal has a current applied along it.
3d printers need a fine flat level bed.
This video shows how to use linear hall effect sensors to build end stops for 3d printers.
Like infra red diodes or hall effect sensors or even to dirt like inductive sensor as commonly used on dirty cnc machines.
There are many options for a 3d printer s bed sensor and even more misconceptions about what they can and should do.
