Properly configuration of the parallel port mapping is critical for your machine to respond accurately to software commands. The universal pin assignment for the BL-MACH-V1.1 D302 breakout board follows this standardized topology: LPT Pin Number Hardware Function / Target Component Signal Type Onboard Relay Control (Coolant/Spindle) Output (Digital) Pin 2 Axis 1 (e.g., X-Axis) Pulse / Step Output (Pulse) Pin 3 Axis 1 (e.g., X-Axis) Direction Output (Digital) Pin 4 Axis 2 (e.g., Y-Axis) Pulse / Step Output (Pulse) Pin 5 Axis 2 (e.g., Y-Axis) Direction Output (Digital) Pin 6 Axis 3 (e.g., Z-Axis) Pulse / Step Output (Pulse) Pin 7 Axis 3 (e.g., Z-Axis) Direction Output (Digital) Pin 8 Axis 4 (e.g., A-Axis) Pulse / Step Output (Pulse) Pin 9 Axis 4 (e.g., A-Axis) Direction Output (Digital) Pin 10 Emergency Stop (E-Stop) Button Input (Isolated) Pin 11 Limit Switch / Home Switch (X-Axis) Input (Isolated) Pin 12 Limit Switch / Home Switch (Y-Axis) Input (Isolated) Pin 13 Limit Switch / Home Switch (Z-Axis) Input (Isolated) Pin 14 Reserve Output Port / Alternate Enable Output (Digital) Pin 15 Tool Probe / Z-Axis Height Setter Input (Isolated) Pin 16 Overall Driver Enable Signal Output (Digital) Pin 17 PWM Spindle / 0-10V Speed Voltage Converter Output (Analog) Pins 18-25 Ground (GND Connections) System Ground Step-by-Step Installation and Software Setup

Fix: Check if the 5V USB cable is connected. Ensure the "Charge Pump" or "Enable Pin" setting in your software matches Pin 16, or verify that the external stepper driver power lines are fully energized.
