The eMAKER Huxley 3D printer uses the Sanguinololu version 1.3a electronics to control all of its functions. This is powered from a 120W laptop power supply, and controls the hot end and heated bed, as well as axis motion. The Sanguinololu electronics can be configured in many ways, and the eMAKER Huxley kits have been put together with a specific bill of materials, all of which will be detailed below.
The RepRap wiki has a comprehensive guide to the Sanguinololu electronics here.
|IC100||FT232RL||Surface mounted on the underside of the board.This can be done with a standard soldering iron and some flux. See these videos for inspiration:http://www.youtube.com/watch?v=bvo8Xj_yn3whttp://www.youtube.com/watch?v=t06malVew40|
|J1||USB||USB Type B socket|
|R2||100k||1/4 watt axial resistor|
|R1||1k||1/4 watt axial resistor|
|R9||4k7||1/4 watt axial resistor|
|R6||10k||1/4 watt axial resistor|
|LED1||LED||Red LEDThe short lead (negative) should be in the hole closer to the center of the board.|
ATMEGA644 socket, careful attention should be paid to the polarity of the socket.
|0.1″ Female headers|
|0.1″ Male headers (use spare female headers to align the double headers. The two header sets (::::::: ::) in the bottom right corner also need to be aligned to take the SD breakout board)|
|Microstep setting shunts. 12 required to set all axes to 1/16th microstepping, and one for the autoreset.|
|C16||4.7uF||Capacitor (shorter leg is for the hole marked with a “-”)|
|C9; C10||10uF||Capacitor (shorter leg is for the hole marked with a “-”)|
|C1 C2 C3 C4||100uF||Capacitor (make sure they lie flat like in the picture, as the stepper drivers will be slotted in over them)|
|Mosfets for driving heaters|
|Screw terminals for heater outputs and power input|
|Atmega 644P microcontroller|
|A4988||Pololu Stepper driver|
|0.1″ male header pin strip cut in half.|
|0.1″ male header pins pushed into Sanguinololu female headers.|
|A4988 stepper driver PCB dropped onto 0.1″ male header pins for soldering. (The heatsink can be attached to the A4988 chip later using the technique described in the Hot End assembly instructions. )|
