Marlin 3D Printer Firmware for Monoprice Maker Select V2 (Wanhao Duplicator i3)

Please use the 1.1.x branch as that is the only branch I'm modifying in this fork.

Changes in this Marlin fork

Branch 1.1.x has been reset to tag 1.1.8 and configuration.h has been modified from a configuration.h found here:,809741

Special Instructions

When compiling this firmware the only error I encountered was around u8glib missing. I resolved this in the arduino (1.8.7) IDE by going to "tools -> manage libraries" and installing U8glib by Oliver Version 1.19.1


Please use this at your own risk. I accept no responsibility for the modifications posted here. This configuration compiles and works for my stock Monoprice Maker Select V2 on the original Melzi board but I have likely not tested all scenarios and modifying your firmware will void your warranty and can potentially damage your printer.

Additional Info

Before installing this firmware I burned a bootloader on my melzi board using an Arduino Uno clone (found here: and the instructions from a Youtube video here: until about the 6:45 mark. The rest of the instructions on that video are around updating the Repetier firmware which I couldn't get the latest versions to fit on the small Melzi board so I switched to Marlin and here we are.

You can’t perform that action at this time.
