Sensor is excellent - But don't forget about your physical size! I've been working on a Printrbot Jr metal 3d printer that was given to me with a bad motherboard, which I replaced with a MKS Gen L board

5/5

The only issue was that the board didn't work with the original Z-drive. sensor for axis (6-axis) 36 volts, PNP, 4 mm). I needed a 5 volt NPN transistor. I ordered this one after a few failed attempts to adapt the original using some circuits I found. I also needed a longer sensing range because the old one wouldn't work with the heated glass bed. br>br>This one was a no-brainer. and plug-in-and-play - Just make sure the right wires are connected to the right pins and that the firmware is configured correctly. There's no need for any additional circuitry. The only issue I had, which was entirely due to my inattention, was that this sensor has a significantly larger diameter than the original (M18 vs M12), necessitating some rework on the mounting. But, after that, it's fantastic! However, if you're replacing sensors like I was, keep this in mind.

It is powered by a 5 volt battery

5/5

My ender 3 pro 3D printer uses it as a homing / bed leveling sensor and it works great. The 5 volt supply is directly connected to it. For this, I've created a sturdy mount that you can print. Search "Ender 3 Leveling M18 Inductive Sensor Bracket" on Tinkercad or Thingiverse to find it.

It performs as expected and is extremely reliable

5/5

I use it with my Ender 3 Pro and Skr mini e3 v2 board, and I connected the ground and signal wires to the Z-Wave connector. endstop pin and 5V into one of the 5V pins between the Z endstop and the Neopixel ports (Find out what the board's pinout is. ) It's on the PC2 pin in Klipper, but the probe was always reading as triggered, so I had to add an exclamation mark. The readings from the probe are extremely consistent.

It operates at 5 volts! I was a little apprehensive about getting this because most of these sensors require more than 5V to function properly on 3D printers

5/5

But, to my delight, it works at 5V at the recommended distance (8mm on my Fulament spring steel sheet)! Despite the fact that it arrived scratched, it still works.

On aluminum, it doesn't work very well

3/5

This sensor does not activate until the 4mm glass on my hot plate is struck. I also have a Balitensen sensor that provides about 1mm of resolution and runs on 5V. br>br>On steel, it gives about 8mm.

As advertised, it did not work on my CR10 Pro

3/5

It couldn't detect the glass bed far enough at first. The printer did not see the output after I changed the bed to have the LED turn on when you get close to it. It had only recently arrived. IT SHOULD NOT BE RECOMMENDED FOR USE WITH A CR10 PRO.
