Open Candle, select the correct COM port, and set the baud rate to . 4. Troubleshooting and Tips
To ensure accurate movement, you must calibrate the steps per millimeter (
Send the command M3 S1000 through the console. Check if the onboard spindle indicator LED lights up. Measure voltage output at the terminal pins. Issue 4: Alarm triggers immediately when homing starts Cause: Electrical noise or inverted limit switch logic.
LaserGRBL: Specifically designed for those using the board to drive a laser engraver.
Some boards use a jumper to switch between Laser PWM and Spindle power. AliExpress Setup and Software
The Annoy Tools board is compatible with several open-source and professional CNC software packages:
: Supports 12V and 5V outputs with or without TTL/PWM modulation. 🔌 Hardware Layout & Connection Diagram
Adjustable driver subdivision for higher precision control. Where to Find the Annoy Tools CNC Board Manual PDF
: A cross-platform alternative for advanced users. Calibration Steps
Before powering your board, ensure your power supply and components match these electrical limitations: Specification 12V – 24V DC 24V is recommended for better stepper torque Main Processor ATmega328P Standard 8-bit AVR microcontroller Firmware GRBL v1.1f (or newer) Compatible with Candle, LaserGRBL, LightBurn Stepper Drivers Integrated A4988 / DRV8825 Adjustable current via onboard potentiometers Spindle Interface PWM / Analog (0-5V or 0-10V) Supports DC motors up to 10A or external VFDs Laser Interface 3-pin (VCC/GND/PWM) or 2-pin Supports 12V or 5V TTL modulation PC Connection USB Type-B or Micro-USB Requires CH340 or CP2102 serial drivers 3.
