The 1.8-degree step angle offers 200 full steps per revolution, which becomes significantly more precise when combined with microstepping through the driver.
DM556S Stepper Motor Driver: Digital Precision and Smooth Motion
The DM556S stepper motor driver is a key performance component in this kit. Unlike older analog drivers, it uses modern 32-bit DSP digital processing technology.
DM556S Driver Specifications
| Specification | Details |
|---|---|
| Driver Model | DM556S |
| Output Current Range | 1.0A – 6.0A |
| Microstepping Range | 200 – 51200 subdivisions |

| Input Voltage | 20 – 50V DC |
| Motor Compatibility | Nema 17, Nema 23, selected Nema 34 |
Microstepping and Motion Quality
The DM556S features built-in micro-subdivision technology. Even when configured at lower subdivision settings, it achieves a high subdivision effect internally. This results in:
- Smoother low-speed motion
- Reduced vibration and resonance
- Improved surface finish during engraving or cutting
- Ultra-low noise operation
This is especially beneficial for CNC engraving machines where fine detail and quiet operation are important.
Mach3 4 Axis USB Motion Control Board
The 4 Axis USB Mach3 control board serves as the communication bridge between your computer and the stepper drivers.
Control Board Specifications

Driver-Free USB Operation
One of the standout advantages of this control board is its driver-free USB interface. As long as Mach3 software runs on your system, the board can operate without installing additional drivers. This simplifies setup and reduces compatibility issues.
Stable Signal Transmission
USB communication ensures consistent pulse output to the drivers, minimizing signal distortion and improving axis synchronization. This is essential for multi-axis interpolation during complex toolpaths.
Power Supply Configuration and Electrical Stability
Reliable power delivery is critical for CNC systems, especially under load. The RATTMMOTOR 4 Axis Nema 23 Stepper Motor Kit includes two dedicated switching power supplies.

Advantages of Dual Power Supplies
Separating motor power from control electronics improves system stability by:
- Reducing electrical noise
- Preventing voltage drops during rapid acceleration
- Protecting sensitive control circuits
The 36V supply provides sufficient headroom for high-speed operation while maintaining torque at lower RPMs.
