Unlock 3D printing and engraving with CNC Shield V3. This board expands your Arduino setup to support 3D printing and engraving projects. 4x A4988 drivers. Control 3 stepper motors effortlessly with integrated and removable A4988 drivers (compatible with DRV8825). GRBL 0.9 compatible. Seamless integration with opensource firmware for easy Gcode processing and control. Precise control. Microstepping jumpers enable accurate control over stepper motor movement for reliable results. Key benefits and use cases Extends Arduino capabilities for compact, lowcost CNC and engraving projects without requiring dedicated controllers. Flexible driver configuration: you can use the integrated A4988s and still remain compatible with DRV8825 drivers. Opensource workflow: works with GRBL 0.9 for straightforward Gcode handling and project prototyping. Fine control over motion: microstepping jumpers provide precise motor movement, improving cut/engrave quality. Compatibility and performance highlights Designed around the CNC Shield V3 platform to work with Arduino ecosystems. A4988 drivers are included (integrated and removable) and maintain DRV8825 compatibility for broad motor driver interchangeability. GRBL 0.9 compatibility ensures alignment with common opensource firmware and Gcode environments. Microstepping jumpers enable resolution for accurate motor positioning. Practical applications Build a compact desktop CNC engraver for signs, nameplates, and light engraving on wood or plastic. Upgrade an existing Arduinobased motion controller to drive up to three steppers with flexible driver options. Experiment with GRBLbased motion control and Gcode workflows for hobbyist robotics and prototyping. Design and usage notes Intended as a shield for Arduinocompatible systems to enable CNC and engraving functionality. Provides multiple motor drive options through A4988 and compatibility considerations with DRV8825. Microstepping configuration offers adjustable precision suitable for entrylevel to intermediate projects.
