MACH3 Engraving Machine CNC 5-Axis Stepper Motor Driver Board

Wide voltage input: 12–24V with anti-reverse protection.

Relay output: Single relay output port (P17) for spindle switch control.

Analog output: One optocoupler-isolated 0–10V analog voltage output (P1) for inverter control, enabling spindle speed adjustment.

PWM output: P1 can also function as a PWM output to control spindle governor with optocoupler input.

Driver compatibility: Supports common or common yang connection, with 5V input level for driver control.

Wide Voltage Input (12–24V): Supports a broad voltage range with built-in reverse protection for safe and stable performance.

Spindle Control: One-way relay output (P17) to easily switch spindle operations on or off.

Speed Regulation: Optocoupler-isolated 0–10V analog output (P1) allows accurate control of spindle speed via inverter.

PWM Output Compatibility: P1 port also functions as a PWM output, compatible with 5V input level drivers (common or common yang).

Description
Review

This stepper motor wiring uses a unipolar configuration, but it can also be connected as bipolar by pairing the orange-blue and red-yellow cables. It is designed to be compatible with a variety of plastic pulleys and gears, including FS2-3493-000 Gear 49T (Ø46mm), FS6-0084-00 Gear 26T (Ø24mm), FS5-3807 Gear 18T (Ø16.5mm), FS6-0066-000 Gear 35T (Ø32.6mm), FS6-0864 Gear 49T (Ø46mm), and FS6-0085-000 Gear 40T (Ø37.5mm). In addition, this motor supports multiple timing belts such as S3M-276 (270mm x 6mm), S3M-699 (680mm x 6mm), S3M-384 (370mm x 6mm), and S3M-339 (330mm x 6mm). This makes it a versatile choice for CNC machines, 3D printers, and robotic applications where precise linear motion and reliable performance are required.
