Annoy Tools produces several popular CNC control boards, most notably the and Rebild 3.3 models. These are 3-axis or 4-axis controllers often based on the STM32 or AVR microcontroller architecture. They are favored by the DIY CNC community for their integrated features (SD card support, offline controller support, and Bluetooth/Wi-Fi on newer models).
kits, are versatile GRBL-based controllers. Whether you have the standard 3-axis board or the upgraded 32-bit ARM version, these boards act as the "brain" of your CNC, translating G-code into physical movement. For a full visual guide, you can access the Annoy Tools CNC Board Manual PDF on Google Drive. Board Specifications & Compatibility : Most boards ship with : Available in 8-bit (ATmega328p) or high-speed 32-bit ARM Connectivity for PC communication or a dedicated port for an offline controller : Integrated stepper drivers (supporting NEMA17/23 motors). Peripheral Support : Includes dedicated ports for XYZ limit switches laser modules (12V/5V with TTL). Core Setup Steps Safety First : Always connect or disconnect wiring while the power is switched OFF to avoid blowing driver chips. Hardware Connection Plug the 4-wire stepper motors into the X, Y, and Z ports. annoy tools cnc board manual pdf
