Marlin 1.1.x firmware for the MKS Base V1.5 on an Anet A8/Tronxy P802MA (AUTO LEVELING)
I modded the a fresh copy of Marlin 1.1.x to enable autoleveling on my P802MA variant of the Anet A8.
Make sure you verify all settings in the configuration.h file because your Z probe or bed limits may be different than mine. Install Arduino 1.8.2
Click tools- Set board type to Arduino Genuino/Mega or Mega 2560 Set Processor ATMega 2560 Set Com Port
Click "Sketch" - "Include Library" - "Add .ZIP Library" to add the U8Glib library if you are using the MKS TFT32 full graphic display.
Upload and enjoy.
