Wonky print bed? No problem with auto bed leveling

So you have upgraded your printer to Tinyfab CPU. It's time to make the most of extended features of the onboard smoothieware software. This time is the auto bed leveling for your uneven bed surface.

To use this feature you will need to install an additional sensor. There are a number of different type of sensors around. These includes the infrared, contact, laser, capacitive or inductive. They all have their pros and cons, this blog will focus on inductive sensor on the cetus 3d printer.
