I tried editing my own Marlin firmware from the latest version, but as I moved further down the config.h, I read that auto level on deltas aren't implemented, is this so? Or did I misunderstand something.
Auto Level exists on Delta printers. But it works a little bit differently. Do you have a Z-Probe? You need a Z-Probe to do Auto Bed Leveling with Marlin.
