For makers, hobbyists, and small-business owners using desktop CNC machines—particularly the popular —the controller board is the brain of the operation. Annoy Tools specializes in providing versatile, GRBL-compatible boards that allow for precise engraving and cutting.
For , installation is simple: download the latest version from GitHub, run the .exe file, select the correct COM port (from Step 2), set the baud rate to 115200, and click Connect .
Set to 1 if you have limit switches installed to stop the machine upon crashing.
The board communicates with your computer via a USB-C port, and most of these boards use a USB-to-serial chip. Here's how to get the driver set up: annoy tools cnc board manual pdf

Standard wiring sequence: (typically Black, Green, Red, Blue).
Always use a fan; stepper drivers overheat quickly. Set to 1 if you have limit switches
Connect the spindle motor or laser module to their respective ports.
The manual is technically accurate regarding hardware specs, but it often assumes the user has prior CNC knowledge.
Download the PDF for the pinout diagrams, but rely on the broader CNC community (forums and YouTube tutorials on GRBL configuration) for the actual logic and troubleshooting of your machine. Do not expect the PDF to teach you how to run a CNC; expect it only to tell you how to power the board up safely. Always use a fan; stepper drivers overheat quickly
2-pin ports separate the constant 12V power from the TTL/PWM control signal.
Allows for precise stepper motor control.
