D302 |verified|: Bl-mach-v1.1

Solution: Verify your PC’s BIOS settings. The parallel (LPT) port must be set to rather than "Output Only" to allow bi-directional signals like limit switch flags to return to the computer.

BL-MACH-v1.1 D302 is a hypothetical/unnamed model/version (assumed to be a machine-learning model or device revision). This write-up assumes the user wants a practical summary covering purpose, architecture, performance, deployment, and troubleshooting—useful for engineers, product managers, or evaluators.
