However, I don’t have any verified technical specifications or official references for that exact model name in my current knowledge base. It sounds like it could be:
The BL-MACH-V1.1 D302 board layout typically includes the following terminals:
: If using the onboard relay to start the spindle via G-code (M3/M5 commands), navigate to Spindle Setup, locate the Relay Control matrix, and assign Output #1 to Pin 17. Legacy Considerations and Troubleshooting Bl-mach-v1.1 D302
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.
SRD-05VDC-SL-C rated for up to 10A switching capacity. SRD-05VDC-SL-C rated for up to 10A switching capacity
Powering the board is straightforward. Connect the board's USB port to your computer using a standard USB A to B cable. This powers the board's logic circuits. To power the peripherals (such as the relays and the isolation for the inputs), you connect a separate 12-24V DC power supply to the "12-24V" and "GND" screw terminals. The board has a reverse polarity protection feature, but it is still wise to double-check your connections to avoid damage.
