Cloned RAMBo 1.4 Motherboard MEGA And Stepper Drivers All On One Integrated PCB For /Lulzbot Taz6/3D Printer
Description

Details

Descriptions:
 
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 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. 
 
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
 
Logic: 
 
●  MEGA compatible Atmega2560 and Atmega32u2 processors are compatible with all RAMPS class firmwares
● Crystals for both usb and mcu (timing accurate to 10ppm)
● 4 Thermistor jacks
● All extra pins broken out on both processors (allows using the 32u2 for LUFA AVR programmer, etc.)
● 2 channel SDRAMPS compatible SPI breakout
 
About Motor Drivers: 
 
● 5 A4982 1/8th microsteps motor drivers with 1,1/2,1/4,1/16 as options (2 connectors for Z-axis)
● Digital Trimpot for stepper current control
● Current limit on driver IC VCC to prevent permanent latchup
● Microstep mode configured by MCU through firmware (no jumpers needed)
● Test points for driver control signals
● Step and Direction pins are on their own ports for synchronous movement capability
● Extra driver ports broken out for up to 3 additional drivers (some of the motor extension pins are shared with max endstop and a pin allocated for SPI-SS extensions)
 
PWM DC outputs (Extruders, Fans, Etc.)
 ● 6 outputs
 ● Low resistance mosfets for cool running
 ● Indicator led for each channel
 
Power: 
 ● Three independent power rails
 ● Heated Bed, 15A 12-35V
 ● Extruders + fans and logic, 5A 12-35V (fuse can be exchanged for up to 10A capacity)
 ● Motors, 5A 12-28V (fuse can be exchanged for up to 10A capacity)
 ● Built in SMPS for 5V generation from 10V-26V Vin
