: Arduino-based system, typically utilizing the ATmega328p chip. Firmware : Pre-installed with GRBL 1.1f .

Annoy Tools boards run on standard open-source GRBL firmware. You do not need proprietary tools to control your machine. Recommended Control Software

Here are the typical specifications for a standard Annoy Tools GRBL 1.1F 3-axis controller board:

Use the TTL/PWM pin for modulation (power control) and the 12V/GND pins for power. 3. Limit Switches (Endstops)

It comes with 3 integrated A4988 stepper motor drivers, allowing direct connection to four-wire stepper motors.

💡 Always backup your GRBL settings by typing "$$" into the console and copying the output to a text file before making any hardware changes. To help you get your machine running, could you tell me:

The motor may be starved for current. Gently turn the small potentiometer (vref) next to the corresponding stepper driver clockwise with a ceramic screwdriver to slightly increase the current.

Finding the official manual can surprisingly be the most difficult part of the process.

(Max Spindle Speed): Set this to match your CAM software (e.g., 1000010000 (Laser Mode): Set to for laser mode, for spindle mode. Troubleshooting the Board
