Introduction:
This List Is for Pololu MegaShield, or for Short Slopes. It Is Designed As a Low-cost Small Packaging for the Reprap Needs to Adapt to the Entire Electronics. the Oblique Interface and Powerful Mega Platform of Mega Have Ample Expansion Space. the Control Electronics on the Stepper Driver and an MEGA Shield Extruder Are Easy to Maintain, Replace Parts, Upgrade Capabilities, and Expand with Modular Design Including Plugins. in Addition, some Expansion Boards Can Be Added to the System As Long As They Are Saved As the Main Ramp Board at the Top of the Stack.
This Board Is Mainly Based on Adrian's Pololu Electronics and Tonok's Work. Copper Etching Is a Recommended Method for Resistance to Vickers. Also Inspired by Vick's Work on Easydrivers. the Design of the Circuit Is Mainly Based on Adrian's spoolou_ Electronics Joaz Rep Rap Source Com Provides Initial Pin Definitions and Many Design Improvements. Too Much Inspiration, Suggestions, and Ideas from Prusaj, Kliment, Maxbots, Rick, and Many Other Repap Communities.
