PGSA2Z Compatible CNC Shield V3 Engraving Machine/3D Printer/A4988 Driver Expansion Board

  • This shield is designed to allow you to control a CNC router or milling machine from an board.
  • It contains 4 driver sockets which allows compatible A4988 driver modules to be inserted providing the ability to drive 3 stepper motor axis (X,Y, & Z) plus an optional 4th auxiliary motor. Additional connectors provide easy connection of end stop sensors and control buttons.
  • GRBL 0.8c compatible. (Open source firmware that runs on an UNO that turns G-code commands into stepper signals)
  • 4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins D12 and D13)
  • 2 x End stops for each axis (each axis pair shared by same IO pin) Spindle enable and direction connection.

(A4988, Drv8825, And Others) Jumpers To Set The Micro-Stepping For The Stepper Drivers. (Some Drivers Like The Drv8825 Can Do Up To 1/32 Micro-Stepping ) Compact Design. Stepper Motors Can Be Connected With 4 Pin Molex Connectors Or Soldered In Place. Runs On 12-36v Dc. (At The Moment Only The Pololu Drv8825 Drivers Can Handle Up To 36v So Please Consider The Operation Voltage When Powering The Board.)

SPECIFICATION

  • Enlarged board to add a 4th Axis that can clone the X, Y, or Z-axis. With a 4th option to use pin D12-13 to control it.
  • Added a breakout header for all the Axis’s.
  • Added a communication header for UART (Serial) and I2C.
  • Added a connector for an optional fuse. (Fuse not supplies as it needs to be selected for the current that will be used.)
  • Capacitors are mounted horizontally giving more clearance between them and the stepper drivers. Good for ventilation.
  • Added a pull-up resistor on the axis enable pins. This prevents the pin from being in a floating state.
  • Added 2 mounting holes.
