The board comes pre-flashed with GRBL, but settings often need tuning for specific machine builds: Standard Parameters : Essential settings include for steps/mm, and for axis acceleration. Laser Mode : To use a laser, the setting must be set to Firmware Updates

While Annoy Tools CNC boards provide excellent value for hobbyists, the documentation is decentralized. The manual is an essential tool for wiring safety and firmware configuration but requires proactive archiving by the user. If a user cannot find the specific PDF, searching for the specific board revision (e.g., "Rebild 3.2 manual") on GitHub or OpenBuilds is the most reliable alternative.

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.
