Whenever there are homing or leveling issues, we now ask everyone to follow a standard procedure to gather more information:

• Download Marlin bugfix-2.1.x to test with the latest code. You will need to port your config/settings to this version.
• Enable DEBUG_LEVELING_FEATURE and M114_DETAIL and re-flash the firmware.
• Connect to your printer from host software such as Pronterface, Repetier Host, or OctoPrint.
• Send M502 and M500 to ensure your Configurations are applied.
• Issue the command M111 S247 to enable maximum logging.
• Perform a G28 to do your standard homing procedure.
• Perform a G34 to perform the Z Steppers Auto-Alignment procedure.
• Perform a G29 to probe the bed. This will also enable bed leveling.
• Do some of the moves that revealed problems before. Take notes.
• Copy the log output into a .TXT file and attach it to your next reply.

Repeat this procedure, if needed, to demonstrate inconsistencies. From these logs we should hopefully get a better idea of what's going on with your machine.
