Bl-mach-v1.1 D302 [exclusive] Jun 2026

Provides 0-10V analog voltage for spindle speed control. Pinout Configuration

The BL-MACH-V1.1 D302 packs specialized industrial logic into a compact form factor:

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

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 Bl-mach-v1.1 D302

The is a 5-axis Breakout Board (BOB) designed to be used specifically with parallel port (LPT) controlled software, most notably Mach3. It takes the low-voltage, low-current signals from the LPT port and routes them to stepper drivers (for axis motion) and peripheral controls (like spindle speed or limit switches).

Pins P11, P12, P13, P15 (usually) are used for home and limit switches. Spindle Control: P17 (Relay), 0-10V port.

The typical pin assignments for the BL-MACH-V1.1 in Mach3 are:

Includes optocouplers for signal isolation, protecting your computer from motor noise or electrical spikes.

The Bl-mach-v1.1 D302 packs a significant amount of functionality into a compact, green circuit board. Its specifications make it a versatile workhorse for various small to mid-sized CNC projects. and other parallel control software like KCAM4, EMC2,

The is a fundamental component for any DIY CNC project relying on the Mach3 software platform. Its ability to provide robust optocoupler isolation while managing 5 axes of motion makes it an invaluable, budget-friendly choice. By properly connecting the 12-24V supply and mapping the pins correctly in Mach3, users can achieve reliable and precise performance for their CNC machining needs.

All input signals are isolated via light lotus root (optical coupling) to ensure high-speed signal integrity and hardware safety. Spindle Control:

: Connect the PUL- , DIR- , and EN- terminals of your stepper drivers to the corresponding numeric pins on the breakout board, jumping all positive terminal inputs ( PUL+ , DIR+ , EN+ ) to the board's shared 5V output line. Software Configuration (MACH3 Setup)

All input signals pass through "light lotus root" (optical) isolation. This acts like a digital firewall, ensuring that if a motor shorts out, the high voltage never reaches the computer. The Conductor (P17 Relay):

is enabled and the correct address is set (usually 0x378 ).
