Review on 🔧 Geeetech Precision Accessories for Enhanced Bed Leveling by James Roper

Good accuracy at a great price. I got an accuracy of 0.003324mm from this sensor. This is MUCH more than enough for any 3D printer. It is very easy to install, just run the cable to the controller and plug it into the appropriate port. Then update the firmware to a version with ABL enabled. Since my bed is not very uneven, I chose the 4x4 grid and found that my bed had a deviation of 0.1 mm. I would say it's pretty flat. Tip: Bring the bed up to temperature before performing the leveling process. Using the web viewer, I was able to see the difference between the cold bed and the hot bed due to thermal expansion of the surface. I will install these sensors on all my printers.
