Elecbee Mach3 USB CNC Motion Controller Board 100kHz 4-Driver Output, 4 Optocoupler Inputs, 4 Relay-Drive Outputs, 0-10V Spindle

Elecbee 100kHz Mach3 USB CNC Motion Controller Board

The Elecbee Mach3 USB CNC motion controller board transfers motion commands from a compatible Mach3 computer installation to external stepper or servo motor drivers. It is designed for CNC routers, engraving machines, positioning tables and related motion-control projects.

The board provides four stated motor-driver connections, a supplier-specified maximum step-pulse frequency of 100kHz, four optocoupler-isolated inputs, four relay-drive output interfaces, 0–10V spindle-speed control and electronic-handwheel support.

Axis-Capability Note: The source information states both five-axis linkage and only four motor-driver connections. Because these specifications conflict, this listing does not guarantee five independently connected motor axes. Verify the labeled axis terminals on the supplied board before purchase.

Pulse-Frequency Note: The 100kHz figure is described only as the maximum step-pulse frequency. It must not be interpreted as a guaranteed simultaneous 100kHz output on every axis.

External Stepper or Servo Drivers

The controller outputs step and direction signals to compatible external motor drivers. It does not provide the current required to power a stepper or servo motor directly.

Each motor requires a suitable driver and power supply. Confirm the driver\'s pulse-input voltage, common-anode or common-cathode wiring, signal polarity and maximum input frequency before connection.

Configure steps per unit, maximum velocity, acceleration, direction polarity and homing behavior in Mach3 before operating the machine.

Optocoupler-Isolated Inputs

Four isolated input channels can be assigned to compatible limit switches, home sensors, tool-zero probes or other machine-control signals. Optocoupler isolation helps reduce the transfer of electrical interference between field devices and the control circuit.

Confirm the required input voltage, active-high or active-low behavior and common-terminal arrangement. These electrical details were not included in the supplied specifications.

Emergency-Stop Safety: A software input may request an emergency stop in Mach3, but it cannot guarantee removal of hazardous machine power. Use a properly designed hardwired safety circuit where emergency stopping is required.

0–10V Spindle-Speed Control

The 0–10V analog output can send a spindle-speed reference from Mach3 to a compatible variable-frequency drive or spindle controller. The drive must support an external 0–10V analog command input.

This is a low-power control signal rather than a motor-power output. Verify the analog input, signal common, scaling parameters, grounding and electrical isolation requirements of the connected drive.

Relay-Drive Outputs

Four isolated output interfaces can control compatible external relay circuits assigned to functions such as spindle start, forward or reverse commands, coolant pumps and auxiliary equipment.

Output Qualification: The supplied specification describes relay-drive interfaces, not four confirmed onboard power relays. Do not connect a spindle, pump or other high-current load directly to these outputs.

Verify the output voltage, current capacity, polarity and required relay-coil interface before installation.

Electronic Handwheel and Status LED

The board supports connection to a compatible electronic handwheel for manual jogging and machine setup. Confirm the handwheel connector, supply voltage, signal type and pinout before wiring.

One onboard LED indicates basic controller connection status. It does not independently verify correct motor-driver, input, output or spindle configuration.

Software and Installation Requirements

The controller requires a compatible Mach3 installation and the correct motion-controller plugin. Mach3 software, licensing files, USB drivers or plugin files are not stated as included with this product.

Verify compatibility with the intended computer operating system and Mach3 version before purchase. Do not download unofficial license files or unrelated controller plugins.

Applications

Suitable applications include compatible CNC routers, engraving machines, small milling projects, positioning tables and automated motion systems that use Mach3 with external motor drivers.
