I downloaded Marlin from http://download.makeblock.cc/data/melephant/Marlin.rar
Link is provided in the mElephant description http://makeblock.com/melephant-3d-printer
But it is not working at all - I also found many complaints on the internet. Z axis is moving in opozite direction, auto level is not working and so on.
Could you provide the link to the latest/development version of the Marlin Firmware?
