RAMBo 1.4

UltiMachine


This is RAMBo v1.4. The RAMBo board is an all in one 3D printer motherboard. It is a full remix of our RAMPS design with the Arduino MEGA and stepper drivers all on one integrated PCB. That is where it got the name RAMBo - (R)epRap (A)rduino-(M)ega-compatible (M)other (Bo)ard. This is the same board you will find in the Lulzbot Taz6 Printer

RAMBo v1.4 - The major difference over the previous version is the integrated LCD connector for Smart LCD Controllers. The EXT2 and SPI headers were re-arranged to remove the need for an adapter. This change is backwards compatible with firmware for previous versions of Rambo that normally utilize the RamboLCD. 

Major Features - 5 x integrated 1/16th microstep motor drivers, 5 PWM Mosfet outputs, 4 thermistor inputs, digital trimpot (no tiny knobs to tweak), SMPS supports hostless printing on power supply voltages from 10-24V DC, 3 independent fuse protected power rails, LUFA USB, high quality connectors, did I say hacker friendly ...

RAMBo is designed to work with the current RAMPS generation firmwares with minimal modifications to add firmware control of the digital trimpots and the microstep setting pins.
