# TruCUT -- leftover RuiDa RDC644XG English controller handbook

English leftover RuiDa **RDC644XG Controller User Manual** from the local cncu.co.za TruCUT **Component Manuals** tree. 51 A4 pages (WPS / RuiDa, copyright 2016). Third-party Shenzhen RuiDa Technology Co., Ltd (www.rd-acs.com) controller handbook AM stores. Covers controller overview and model comparison, installation size, panel/interface photos, CN0/HMI/Udisk/PC-USB/Ethernet plus CN1-CN6 and AXIS_X-U wiring, glass-tube and RF-CO2 laser-power examples, step-servo driver and IO examples, and the HMI (speed/power/layer, Z/U menu, axes reset, laser/origin/factory, autofocus, language, IP, user parameters including array/back-position/focus/backlash). **No pricing.** Distinct MD5 from already-copied `RDC644XG-S-Control-System-User-Manual-V1.3.pdf` (6243176 / `AFDC83AE13E53EA42597C2B4482FF116`). Prefer the already-copied **644XG-S V1.3** on 644XG-S hardware; prefer this leftover for the unused non-S **RDC644XG** 2016 English controller book. Not a twin of leftover-skipped older RDC5121 / RDC6445G V1.0.

MD5-checked against already-copied Ruida 644XG-S V1.3 and other TruCUT ruida PDFs -- not a twin.

Prior leftover English remain: [`RDWelder-SW-Handheld-Laser-Welding-System-User-Manual-V1.2.pdf`](https://cncu.co.za/TruCUT-CO2-Laser-Machine/Ruida%20Motion%20Control/User%20Manuals/RDWelder-SW%20Handheld%20Laser%20Welding%20System%20User%20Manual%20V1.2.pdf) (609538); [`RDEncLas400G-Intelligent-Laser-Control-Module-User-Guide.pdf`](https://cncu.co.za/TruCUT-CO2-Laser-Machine/Ruida%20Motion%20Control/User%20Manuals/RDEncLas400G%20Intelligent%20Laser%20Control%20Module%20User%20Guide.pdf) (2468493); prior 21 Ruida controller/vision manuals including 644XG-S V1.3. Not re-copied this pass.

## Software / drivers

No new PC installer this leftover slice. Prefer already-noted RDWorks V8 **8.01.67** (`Ruida Motion Control\RDWorks V8 Setup 8.01.67 - 20250405.exe`) -- URL-only from the prior TruCUT deepen (not re-HEADed). See `drivers/trucut-software-notes.md`.

TruCUT controller firmware tree is already indexed (`drivers/trucut-firmware-index.md`); **no new firmware this pass** (quiet; still **10** primary + **5** Express/LaserCEO appended).
