LulzBot

For advanced users looking to bring their 3D printing capabilities beyond traditional means, the LulzBot Rambo V1.4 Kit with LCD Harnesses allows seasoned printers to explore more intricate designs and capabilities.Built with the Arduino community in mind, the RAMBo motherboard is compatible with select LulzBot 3D printers including the TAZ 6 and TAZ Workhorse. The 4-layer PCB uses 2 oz copper to ensure optimal throughput, handling high temperatures and uses gold ENIG finishing for greater conductivity. This motherboard supplies you with an integrated Logic board, five microstep motor drivers, test points for driver control signals, six PWM DC outputs, three independent power rails, heated bed support, replaceable NANO2 fuses, and more.Logic Arduino MEGA compatible Atmega2560 and Atmega32u2 processors are compatible with all RAMPS class firmware 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 breakoutMotor 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 6 outputs Low resistance mosfets for cool running Indicator led for each channelPower 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 VinPCB 4 layer 2 oz copper on all layers High quality, High temperature FR4-TG130 PCB Gold ENIG finishing
