FIRMWARE & HARDWARE INFORMATION

Einsy Rambo is designed to work with current RAMPS generation firmware, with minimal modifications, to add firmware motor current control and the microstep setting.

Linux and Mac use CDC interface and have the hardware driver build in. The windows hardware driver can be found here.

The board is preloaded with preconfigured Marline Firmware. To re-flash this board, you can simply use the Arduino IDE with Rambo Add-ons and set the board to ‘Rambo’. Additional Arduino plugin folders can found on Github.

Recommended power supply 12V-24V DC, 16A+
