Internet-Enabled 3D Printer Motion Controller Reference Design

This open source 3D printer motion controller design connects a BeagleBone Black to a 3D printer, turning the 3D printer into an internet-connected device capable of ultra-high-speed printing. With this design, there is no need to connect a dedicated computer to the 3D printer. Once the 3D printer file is loaded into the BeagleBone Black, the 3D printer design will communicate with the 3D printer. This design is based on the Replicape 3D Printer BeagleBone Black Add-on Board. All design files and software are open source and licensed under the GPL. Features AM335x ARM Cortex-A8 processor-based design reduces development time by using an open source design Five stepper motor controllers that can handle up to 2.5A peak current and 1.75 RMS. And are very immune to short circuits and overheating High power MOSFETs for controlling two heater cartridges and a hotbed Thermistor inputs for NTC thermistors. Each input has a filter to suppress high voltage noise spikes generated by the MOSFET and a separate pin ground for cable shielding to the ADC. Software for creating a GUI that includes a 3D model and can control the timing of a variety of stepper motors This subsystem is a designable example subsystem and comes with schematics, BOM, Gerber, and other design files.
