Users looking for the Annoy Tools CNC Board Manual PDF usually do so because something is broken. Here are the top 3 fixes based on the original manual's "Troubleshooting" section.

Because the board is essentially a clone of the Protoneer CNC shield or the standard Arduino CNC shield, the manual is critical for understanding:

| Setting | Default | Recommended (mill) | Description | |---------|---------|-------------------|-------------| | $100, $101, $102 | 250 | 800 (if 8mm lead screw) | Steps/mm for X, Y, Z | | $30 | 1000 | 1000–30000 | Max spindle speed RPM | | $31 | 0 | 0 (PWM active high) | Spindle PWM invert | | $32 | 0 | 0 (mill) / 1 (laser) | Laser mode | | $20 | 0 | 1 | Soft limits (enable) | | $21 | 0 | 1 | Hard limits (enable if switches wired) | | $22 | 0 | 1 | Homing cycle enable | annoy tools cnc board manual pdf

Most Annoy Tools boards follow the H32 layout.

Once you find a PDF that is close to your board, don't read it cover to cover. You only need three things:

Limit pin      →  Board pin (e.g., X limit)
Other wire     →  GND (common ground)
