The manual outlines the critical steps for getting the machine operational:
Follow these steps in exact order to prevent short circuits. Ensure the main power supply is during wiring. Step 1: Connect Stepper Motors
Alter the $3 setting in the GRBL console, or physically flip the 4-pin motor connector 180 degrees on the board. annoy tools cnc board manual pdf
First, let’s clarify the product. "Annoy Tools" typically refers to a generic, low-cost, 3-axis or 4-axis CNC controller board based on the ATmega328P microcontroller (the same chip as an Arduino Uno). It runs the open-source (usually version 1.1f or 1.1h). These boards are often sold on e-commerce platforms like AliExpress, Amazon, or eBay as unbranded or "Annoy Tools" branded CNC shields.
If your machine loses connection, it is often due to electromagnetic interference (EMI) from the spindle or low-quality USB cables. The manual outlines the critical steps for getting

Power Supply Connection
A CNC board manual PDF is a digital document that provides detailed instructions and guidelines for operating, maintaining, and troubleshooting Annoy Tools CNC boards. The manual typically includes: First, let’s clarify the product
This is a power supply issue. The manual recommends a separate 12V supply for the spindle and a different 12-24V supply for the logic. Or, add a large capacitor (1000µF) across the DC input.
Heavy-duty MOSFET-controlled output delivering full input voltage (24V) to drive brushed DC spindles up to 100W–150W.
Install the (often CH340) on your computer.
If the problem persists, try the : Set your machine to its home position and type G28 to see if a specific axis movement triggers the reboot. This helps isolate the issue.
