DC 12-24V CNC 5-Axis Mach3 Interface Board With Optical Coupler For Isolation, USB And Parallel Port, XH2.54 Cable Kit For Stepper Motors, Spindle Control, Emergency Stop, Tool Setting And Limit Switches
✔️ 17 opto-isolated signals, PWM output on P1, USB + parallel
This CNC interface board lets you run Mach3-compatible software via parallel port or USB, handling spindle control, emergency stop, limits, and tool setting for 2D/3D milling and engraving machines.
✅ Fully supports MACH3 and other software that supports parallel port control
✅ USB power supply and peripheral power supply are separated to ensure computer security
✅ 12-24V wide peripheral voltage input, with anti-reverse connection function
✅ All input signals are isolated by optical coupling, and can be connected to emergency stop, tool setting, limit, etc.
✅ One-way relay output port (P17) to control the spindle switch
✅ Open all 17 ports, can be connected with optocoupler drive, can control 5-axis stepper motor.
✅ P1 acts as a PWM output and can control the spindle governor with optocoupler input.
✅ Can be connected to common cathode/anode drive with input level of 5V
✅ Package includes: 1 x Stepper Motor Interface Board, 1 x USB Cable, 1 x Parallel Port Cable, 5 x XH2.54 4P cables
