Bl-mach-v1.1 D302 (PLUS)
BL-MACH-V1.1 (D302) is an interface breakout board used for CNC (Computer Numerical Control) machines, specifically designed to work with
The is a widely utilized, budget-friendly 5-axis CNC interface board designed to bridge the gap between a computer running Mach3 software and CNC machine components like stepper drivers, spindle controllers, and sensors. Often referred to simply as a "BL-MACH-V1.1 breakout board," this component is favored for its simplicity, robustness, and affordability, making it popular in hobbyist CNC routers, DIY laser engravers, and smaller 3-axis to 5-axis milling machines.
: Enable the E-Stop input and map it to Pin 10 or 11 depending on your layout. Set the active state to matching your switch type (Normally Open or Normally Closed). 🛠️ Common Troubleshooting
: Attach a high-density, fully shielded DB25 LPT male-to-male parallel cable between the native computer parallel port and the board. Bl-mach-v1.1 D302
Because the BL-MACH-V1.1 relies primarily on standard parallel port protocols, it requires specific computing infrastructure to operate seamlessly:
