When something goes wrong, you're not alone. Here are some common problems and community-driven solutions.
Power Supply: Connect the barrel jack or screw terminals. Double-check that your voltage matches the board’s specifications (usually 24V for most 3018 models). Software Configuration
Plug the 3-pin laser cable into the dedicated PWM laser port. Do not connect both a spindle and a laser simultaneously. Step 3: Install Limit Switches (Optional but Recommended)
: While the board itself is reliable, users often report that the entry-level machines it controls (like the standard CNC 3018) lack rigidity for anything beyond soft wood, foam, or plastic. Upgrade Capability : The board supports various upgrades, including 500W spindles laser modules
Use the Annoy Tools CNC Board Manual PDF to fine-tune acceleration and feed rates to match your machine's physical limits. 3. Troubleshooting and Support annoy tools cnc board manual pdf
: Most boards accept 12V to 36V DC . If using A4988 drivers, it is recommended not to exceed 24V. Wiring :
Supports 12V/5V TTL and non-TTL lasers, as well as 775 spindle motors. 2. Annoy Tools CNC Board Manual PDF - Overview
$100, $101, $102: Steps per mm for X, Y, and Z. If your cuts are the wrong size, these need calibration.
Once you find a PDF that is close to your board, don't read it cover to cover. You only need three things: When something goes wrong, you're not alone
Supports standard 775 motors (12V–24V) up to heavy-duty, high-power 48V DC brushless spindles pulling up to 500W.
Connect the spindle motor or laser module to their respective ports.
This is the most referenced section of the PDF. It details the specific header pins for:
and is designed to handle 3-axis movements with integrated stepper motor drivers, typically A4988. Control Board Hardware Overview Step 3: Install Limit Switches (Optional but Recommended)
12V–24V DC (Recommended: 24V 5A for spindle motors). Firmware: GRBL v1.1.
is a 3-axis GRBL 1.1 controller, often referred to as a "3-axis driver board" or "GRBL control board" on platforms like AliExpress. It is designed to act as the bridge between your computer (running CAD/CAM software) and the CNC machine's mechanical components. Key Features of the Annoy Tools GRBL Board
The board features several key ports and components necessary for operating a hobbyist CNC router or laser engraver: Controller Chip
