Geeetech Auto Level Sensor 3D Touch for DIY Prusa 3D Printer

The media could not be loaded.  I bought this sensor for my Geeetech A10M because I didn’t want to have to relevel the bed and worry about an unlevel print surface. For only $30, this upgrade has already made a huge difference in my print quality and bed adhesion. The sensor arrived with many other parts that I didn’t expect- mounting screws and other wire parts that can be used for other printers. This means that this sensor is compatible with many other printers and has parts included to attach the sensor to that printer. I mounted the sensor into the 2 screw holes on my A10M, then I adjusted the height from the glass bed. The wiring for the Geeetech printer is simple; as you can see in the picture, all you need to do is connect the two wires. Next, I flashed the new A10M firmware to my A10M easily with the Arduino IDE software. From there, I was able to test the BLTouch’s features- I clicked Auto Home, then Bed Leveling. As you can see in the video, the bed leveling doesn’t take long and is a simple process. It goes to 9 positions on the bed and measures the distance. Since the installation of this sensor, I have been able to print large prints; these prints are completely level, stick to the bed well, and did not warp. Overall, this upgrade for my A10M has made a huge difference.

Got this as a cheaper option for a BLTouch, and dear god is it great. Not having to level the bed yourself is awesome. Once you get it dialed in, you get perfect first layers every time. That said, after like a month or two of using it, the thing just turned blue and stuck out, and my printer refused to print anything. I was afraid of this as I had seen negative reviews claiming this would happen, but after scouring the web for a cause, I performed the most basic task in tech troubleshooting: unplug it and plug it back in. I did this, and it returned to normal function. Hasn't been a problem since.

This probe is great for the money, in some ways I actually like it better than a real BLTouch, the pin is much more robust in my opinion and I like how it deploys. The only real complaint about it is that for whatever reason, and maybe I'm at fault here, but the commands I have on all my printers don't work on this one for reset / release alarm. Which is slightly inconvenient. Other than that I love these probes

It works well. It could be improved if the adjustment screw were a bit more snug in the housing.

Works as described. No issues with bed leveling now. because my printer needs to be portable, it spent way to much time re-leveling my bed after prints. Not any more. If you are reading this review, you know what an auto level sensor should do and not do. I have had no issues.

Did not know I had to solder on the 3D printer control board and add my own extension cables. Must 3D print a mounting bracket to install. None of the bracket STL files found fit the Geeetech i3x Pro printer, so I have to design my own. Still not installed after 3 months.

After dozens of You Tube tutorials I never got this thing to work correctly. Gave it a resting place in the spare parts box.

I was excited to finally do some mild upgrades on my 3d printer but now im forced to repair a sensor out of the box. I have never recived a more botched product. A wire was cut outright. (I am going to have to rewired it due to the length but i would have wanted to test it first) One looks like it touched something hot and melted out of the insulative case. It came with one of the two mounting bolts and none of the nuts. Im not one to write a product review but my god this is out of the packaging and it is completely unusable in every way..
