Product Details:


Application CNC machines, 3D printers, robotics, and other automation projects
Motor Type Supported Bipolar stepper motors
Operating Temperature Typically 0 DegreeC to 50 DegreeC
Supported Stepper Drivers A4988 Stepper Motor Driver (x4)
Model CNC Shield for A4988
The CNC Shield V3.0 allows to build a engraving machine, 3D printer, mini CNC and other
similar devices using your Arduino. It is designed as a shield and can plug on top of an Arduino
requiring no external connections and wiring. There are 4 slots on the
board for plugging in
stepper motor drive module which can drive 1 stepper motor each. Controlling each step stepper
motor requires only two IO pins on the Arduino. Just insert this Arduino CNC Shield V3.0 onto
an Arduino UNO, and install the GRBL firmware
, so it can
quickly build a DIY CNC engraving
machine.
FEATURES:
•
The extension board can be used for Small CNC routers, Carving Machine, 3D Printers,
DIY Laser Cutters, and almost any project where you need to control a stepper motors
with high pr
ecision
•
This shield allows you to control upto 4 stepper motors
•
Controller each stepper motor requires 2 IO Pins only, which saves a lot of IO Pins for
other purposes
•
Arduino compatible
•
Latest Arduino CNC Shield Version 3.10
•
GRBL 0.9 compatible. (Open sour
ce firmware that runs on an Arduino UNO that turns
G
-
code commands into stepper signals)
•
Supports PWM Spindle and direction pins
•
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)
•
Supports Coo
lant enable
•
Supports removable A4988 compatible stepper drivers.
•
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 DRV8825 drivers can handle up to 36V so
please consider the operation voltage when powering the board.)
•
Uses removable A4988 or DRV
8825 compatible stepping driver.
SPECIFICATIONS:
•
Motor Voltage: 8 V to 35 V
•
Logic Circuits Voltage: 3 V to 5.5 V
•
Current: 2 A (MAX)
•
