Azteeg X1
Work in Progress
Contents
Introduction
The Azteeg X1 3DP is an open source controller designed to be used in RepRap 3D Printers and similar cartesian based machines including CNCs. It has all the features needed to run all current and future single extruder designs.
The X1 is based on Sanguino/Sanguinololu and is compatible with most Arduino based firmware(Sprinter, Marlin, Repetier, plus others.). It is pin to pin compatible with the Sanguinololu with the addition of a FAN PIN. The X1 features mostly SMT parts to ease production and reduce cost.
Compatible with Pololu and Stepstick stepper motor drivers with the ability to use an external power source for the motors with higher voltages.
The Azteeg X1 3DP is your low cost, compact and expandable 3DP printer controller. Fully Assembled except for the white connectors where you have a choice between right angle and vertical orientation. Soldering iron required.
Features
- Atmel ATMEGA 644P with FT232RL FTDI USB chip

Getting Started Guide
Hardware
Tools required: Soldering Iron, Solder, Phillips Screw Driver.
1. Solder Connectors - The Kit comes with right angle and vertical connectors so you can choose which configuration is best for your installation. 0.1" pitch terminal blocks can also be used as shown above(Emmanuel's install).Inspect the solder joints after soldering to ensure a good and reliable connection, a loose pin or connector will be difficult to troubleshoot later.
2. Install Heatsinks - Use hardware supplied to fasten the heatsink, Thermal grease is provided but not required for normal operation. Straighten the heatsink before tightening the screws and check that both heatsinks are not touching each other. Use a long nose pliers to secure the heatsink while tightening.
3. Insert jumpers for step size - Consult your stepper drivers documentation to determine your step size settings. See wiring diagram for location and designations of the stepper pins. Push the jumpers all the way down to ensure good contact.
4. Solder TVS Spike supression diodes[optional] - These diodes help clamp down voltage spikes during on-off switching of the Mosfets. It is not required for normal operation but is highly recomended for stability of the board. The pads(SMB) for these are located at the bottom of the PCB near the Mosfet pins, they can be sodered in any orientation as they are non-polarized, bi-directional versions.
|
Caution The TVS diodes supplied are rated for 16v, meaning you have to use a power supply lower than 16v(perfect for that 12v power supply of yours). You need to use a higher rated TVS diode if using a higher voltage power supply. |
5. Solder SDRAMPS/uSD Carrier header[optional]
