If you absolutely cannot find the manual for your generic "Annoy Tools" board:

Let’s be honest: You just unboxed your new CNC, or you’re trying to troubleshoot a stepper motor that’s grinding like a angry cat. You type “annoy tools cnc board manual pdf” into Google... and you get spam, broken links, or a blurry photo of a Chinese PCB with no text.

Why is this so hard? You’re not alone.

In the world of hobby CNC (think Grbl, Arduino-based shields, or generic Chinese controllers), the documentation is often the weakest link. But don’t throw that board against the wall yet. Here is the survival guide to decoding those "annoying" manuals.

Steps/mm = (Motor steps/rev × Microsteps) / (Lead screw pitch)
Example: 200 steps × 16 microsteps / 8mm = 400 steps/mm

Unlike major brands (e.g., Siemens or Allen-Bradley), Annoy Tools does not maintain a comprehensive, easily navigable support page on a primary domain.
