The BL-MACH-V1.1 is a 5-axis CNC interface breakout board designed to work with Mach3 and other CNC control software that supports parallel port (LPT) communication. Key Technical Specifications

Compatibility: Fully supports Mach3, KCAM4, EMC2, and others using a DB25 LPT port. Power Supply: Logic (Digital): 5V via USB or external PC5V terminal.

Peripheral (Power): 12V–24V for external components like sensors and relays.

Isolation: Features optical coupling (opto-isolation) for all input signals to protect your computer from electrical surges. Outputs: 5-Axis Control: Can drive up to 5 stepper motor drivers. Relay Port (P17): Controls spindle power or coolant pumps. Bl-mach-v1.1 D302

PWM Output (P1): Provides 0-10V analog voltage for spindle speed control. Pinout Configuration

The board's pins are typically assigned as follows for Mach3 setup: Pulse (CLK) Pin Direction (CW) Pin X-Axis Y-Axis Z-Axis A-Axis B-Axis Input Pins (Limit Switches/E-Stop): P10: Emergency Stop (E-Stop)

P11 - P15: Customizable for limit switches, homing, or tool probes Setup Requirements

Operating System: Typically requires a 32-bit Windows (like XP or Windows 7) because the 64-bit versions do not support the Mach3 parallel port driver directly. | Parameter | Value | |-----------|-------| | Supply

Cable: You must use a true DB25 parallel cable. Note that generic "USB-to-Parallel" converter cables often do not work for real-time CNC control.

Software Installation: Ensure the Mach3 Parallel Port Driver is installed and active (check Device Manager for any "!" or "?" marks).

If you are having trouble getting the board to "talk" to your computer, I can help you troubleshoot the Mach3 Port & Pins settings or the LPT port address (usually 0x378). Which part of the setup are you currently working on?

The Bl-mach-v1.1 D302 supports USB-C device firmware update (DFU). Use the manufacturer’s "Bl-Flasher v2.3" utility. A common mistake is using the older v1.0 flasher, which corrupts the new EEPROM layout. The BL-MACH-V1

How does the D302 stack against market alternatives?

| Feature | Bl-mach-v1.1 D302 | Beckhoff EK1100 | WAGO 750-352 | | :--- | :--- | :--- | :--- | | Max Digital I/O | 512 points | 256 points | 128 points | | Cycle Time | 250 µs (minimum) | 1 ms (typical) | 500 µs | | On-board Diagnostics | RGB Matrix + Logging | LED only | Web server | | Price Point (USD) | $345 | $410 | $390 | | Proprietary Lock-in | Medium (open for EtherCAT) | Low (standard bus) | High |

The D302 excels in cost-per-node and raw speed, though it lacks the web-based configuration of the WAGO unit.
