Bl-mach-v1.1 D302 Jun 2026

: Supports full configuration for up to 5 independent axes (X, Y, Z, A, B).

: Full path light-coupler (optocoupler) isolation deployed across all input signal loops.

To configure the board in Mach3, navigate to under the config panel and use the following parameters: Bl-mach-v1.1 D302

and other parallel control software like KCAM4, EMC2, and TurboCNC. Axis Control : Can manage up to (stepper or servo motor drivers) simultaneously. Signal Isolation optical isolation

The is a 5-axis LPT interface board that is widely favored for its simplicity, compact design, and robust performance in retrofitting or building DIY CNC machines. It acts as a safety barrier between the computer and motor drivers, isolating signals and managing inputs/outputs. Key Features : Supports full configuration for up to 5

The BL-MACH-V1.1 is engineered for minimal footprint but high utility, packing complete control for up to five axes (typically X, Y, Z, A, and B) into a compact PCB layout.

: Uses optical coupling (opto-isolation) for all input signals and the 0–10V analog spindle output to prevent electrical interference from damaging the PC. Axis Control : Can manage up to (stepper

: Connect a USB cable from your computer to the board to provide 5V to the logic side. The PW(5V) LED should light up.

The board features a separated power structure to protect the computer. The USB port is used strictly to power the digital logic (5V), while an external peripheral power supply (typically 12V-24V) drives the optocouplers and relays.
