Description:

The CNC Stepper Motor Driver Shield V3 is a device that is designed to operate bipolar stepper motors in different step modes such as full-, half-, quarter-, eighth-, and sixteenth-step modes with an output drive capacity of up to 35V and ±2A [1]. This device is compatible with Arduino Uno boards and can be used to control stepper motors for CNC machines and 3D printers [2][3]. The shield typically includes A4988 & DRV8825 stepper motor drivers, which have a fixed off-time current regulator and the ability to operate in Slow or Mixed decay modes [1].

To use the CNC Stepper Motor Driver Shield V3 with an Arduino Uno, one needs to download and install the appropriate software and firmware, such as the Grbl CNC firmware [2]. By using an Arduino Uno and the CNC Shield V3, it is possible to make a CNC miller or control stepper motors for various DIY projects.

In summary, the CNC Stepper Motor Driver Shield V3 is a versatile device that can be used to control stepper motors for CNC machines and 3D printers. It is compatible with Arduino Uno boards and comes equipped with A4988 & DRV8825 stepper motor drivers, allowing for different step modes and output drive capacities. To use the shield, appropriate software and firmware must be downloaded and installed, such as the Grbl CNC firmware.

Specifications:

• Latest CNC Shield Version 3.0 for Arduino.
• GRBL 0.9 compatible. (Open source firmware that runs on a UNO for Arduino that turns G-code commands into stepper signals)
• 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)
• 2 x End stops for each axis (6 in total)
• Jumpers to set the Micro-Stepping for the stepper drivers.(Some drivers like the DRV8825 can do up to 1/32 micro-stepping )
• Runs on 12-36V DC
• Size: 68mm(L) * 53mm(W) * 18mm(H)
