Features onboard A4988 drivers for easy connection to four-wire stepper motors.
Without this map, you cannot correctly wire your endstops or spindle.
By using the Annoy Tools CNC Board Manual PDF, users can:
Spindle Connection: Connect your 775 motor to the spindle terminal. Note that the board uses PWM (Pulse Width Modulation) to control speed.
Finding the official manual can surprisingly be the most difficult part of the process. annoy tools cnc board manual pdf
If you are a hobbyist or a professional woodworker who has recently purchased a Chinese CNC router (often referred to as a "4040," "3018," or "6090" variant), you have likely encountered a small green or red control board labeled . While these boards are cheap and effective for DIY CNC work, finding official documentation is notoriously difficult. The most searched-for item for these users remains the Annoy Tools CNC Board Manual PDF .
If you have tried everything and still cannot operate the unit, consider flashing the board with the latest GRBL firmware using the Arduino IDE—a process detailed in generic CNC manuals that supersedes the original Annoy Tools PDF.
Close any other open CNC software. Ensure the CH340 driver is updated. Try a different USB port or cable.

Searching for this document online often leads to a frustrating maze of dead links, sketchy download sites, or forum threads in foreign languages. Annoy Tools, while popular in budget DIY CNC circles, is not a megabrand like Arduino or Genmitsu. Consequently, their documentation is often fragmented.
CNC controller boards are commonly found in 3018 series CNC routers and laser engravers. Since they often follow the open-source GRBL standard, you can usually find their documentation under titles like "3018 Pro Max Manual" or "GRBL 1.1 3-Axis Driver Board Manual." Official & Community Manuals
Carefully plug in the X, Y, and Z-axis motors, ensuring the Y-axis uses both Y1 and Y2 slots if available.
Usually A4988 or DRV8825 drivers that control the X, Y, and Z axes.
