Firmware / Hardware Information -
Einsy Rambo is designed to work with the current RAMPS generation firmwares with minimal modifications to add firmware motor current control and the microstep setting.
Linux and Mac use CDC interface and have hardware driver built in. Windows hardware driver: RAMBo_USBdriver.zip
A preconfigured Marlin Firmware is preloaded onto the board. To re-flash this board, you can simply use the Arduino IDE with Rambo Addons and set board to "Rambo". There is an Arduino plugin folder on github that exposes additional pins in the Arduino IDE.
Recommended Power supply 12V-24V DC, 16A+.
