The Sanguinololu is a complete electronics solution for driving your RepRap 3D printer, whatever the type - Prusa, MendelMax, Huxley, Mendel90, Repstrap, etc. These boards are version 1.3a, the latest version with support for the latest and most feature-rich firmware - Marlin. Marlin's extra features include the use of an LCD+card-reader+click-encoder combination for true stand-alone printing (as described on our blog and available here). The display+encoder combination also allows real-time alteration and saving of firmware settings - a significant advance in usability. To access these features with the Sanguinololu requires the ATmega 1284 chip because of the extra memory required.

For more information check out the RepRap wiki: Sanguinololu

This is a listing for the kit with all required electronics components, but excluding Pololu stepper motor drivers. This kit comes with the FTDI FT232RL surface-mount chip presoldered so all assembly is by straightforward through-hole soldering.

Please note that all our kits include not only the Sanguinololu but also all the female connector housings and crimp terminals,  and 3 endstops with cables - total extra value over £3.50.  

The ATMEGA 1284P microprocessor comes pre-loaded with the bootloader and a standard Prusa Mendel configuration of the latest Marlin firmware, and is tested for correct operation. You can download Marlin from Github and customise it to your exact requirements using the freely available Arduino software. On request we will supply a brief HOWTO outlining the firmware upload procedure (please email think3dprint3d@gmail.com). Prusa has a good calculator for different hardware configurations here. These settings are easily changed to suit your printer configuration. 

The RepRap wiki has complete information about assembling the boards: Assembly Instructions

Kits include:

• Sanguinololu 1.3a PCB with FTDI chip presoldered and tested.
• All electronic components required to assemble the board as shown in the parts list from the designer.
• Pre programmed ATMEGA 1284. No ISP programmer required
• 3 mechanical endstop switches and cables for these.
• Molex crimp connectors and housings for all connectors (X,Y,Z, Extruder, 3 endstops, 2 thermistors, hotend, heated bed)
• 13 shunts for 1/16 microstepping on all motors and reset jumper.
• You will need to source the Pololu Stepper motor drivers separately - see our listing: Pololus

​

Power Connection Options

The 12V connection to the board needs to be able to carry sufficient current to run 5 motors, the hotend and a heated bed, if you choose to run one through the electronics. You can choose either to use the 4 pin ATX connector from a computer power supply or a screw terminal connection. The ATX connector is simpler if you plan to use one of these power supplies for your printer. The screw terminal is more versatile if you are not yet sure what you will use as a power supply. There is no cost difference between these two options.

Getting Started

This is a summary of the steps required to get up and running.

• Visit the reprap wiki, Sanguinololu page to assemble the kit then check out the wiring diagram.
• Use the crimp connectors to wire up your motors, hotend, heated bed, thermistors and endstops. There is an excellent video by Nophead on how to use the crimp connectors.
• Install your host software, we recommend Printrun / Pronterface, however it will work fine with the other host software options; RepRap host, RepSnapper, ReplicatorG etc.
• Connect to your printer using a standard USB A-B cable; you should use 115200 baud as that is the speed Marlin is set to. Check that you get communication with the printer, the command M105 will return the current temperatures being read from the thermistors. 
• If you are using Windows XP then you will need to load the FTDI drivers from the FTDI website
• Turn on your 12V power supply, try and move the X, Y, Z and extruder axis using your host software. Ensure your hotend and heated bed heats up, ensure the endstops work and stop the axis when triggered.
• Note that if you use the Sanguinololu to run a heated bed directly it will draw approx 10A through the heated bed mosfet, a heat sink is recommended. Also your power supply needs to be at least 300W.
• The firmware is configured for a standard Prusa Mendel. If you have a different setup then you will need to modify it as appropriate. There is a guide to Marlin on the wiki, and Prusa has a good calculator for different hardware configurations here.
• SFACT, an improved version of skeinforge with most of the settings set already is the recommended software to use to turn your STL models into GCode for sending to the printer.
