3D DIY Printer part 2 (Motor Control)

After some research I found some very inexpensive servo motor control electronic boards. Easy Driver stepper motor drivers… these PCBs will allow me to control the motors for each axis, allowing microstepping resolution to full, half, quarter and eighth steps.

I also found a simple schematic which I will use to start basic programming, testing and explore the Sketch code required to allow G Code to be processed. The feed motor for the extruder (A group of parts which handles feeding and extruding of the build material. Consists of two assemblies: a cold end to pull and feed the thermoplastic from the spool, and a hot end that melts and extrudes the thermoplastic.) will be run on another stepper motor and is not detailed in this schematic. I started the layout of all the components on a prototype bread board, and I might just keep it that way for the final build to simplify troubleshooting and modifications.

Next I will prep the computer power supply and run the needed power lines to a breakout board with fuses and a selector switch to allow for a voltage display for each power bus line.
