I’m constantly adding new features to my Tevo Tarantula printer. The latest addition is a bed leveling sensor.
It improves the quality of the prints a lot and in addition you don’t have to adjust the print bed manually every time. If properly configured it runs a measurement sequence of several points (3×3 in my case) before every print and uses this information to compensate during the print.
Where to buy?
You can find it in many places. I bought it here (Banggood)
A ridiculous amount of coffee was consumed in the process of building this project. Add some fuel if you'd like to keep me going!
