A4988 Reprap

DRV8825 ویژه پرینتر سه بعدی

Description:

This shield (HCARDU0086) is designed to allow you to control a CNC router or milling machine from an Arduino board. It contains 4 driver sockets which allows compatible Pololu A4988 driver modules to be inserted  providing the ability to drive 3 stepper motor axis (XY& Z) plus an optional 4th auxiliary motor. Additional connectors provide easy connection of end stop sensors and control buttons.

Features:

GRBL 0.8c compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
4-Axis support (XYZA-Can duplicate XYZ 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.
Coolant enable connection.
Uses removable Pololu A4988 compatible stepper drivers. (A4988DRV8825 and others) see our module HCMODU0068
Jumpers headers to set the Micro-Stepping for the stepper drivers.
Compact design.
Stepper Motors can be connected with 4 pin dupont/molex connectors.
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.)
