==== V5.88 Video Guides ====

  * [[https://www.youtube.com/watch?v=qqHSb980QNQ|Guided Board Tour — Turney's Builds (6:24)]] — close-up orientation covering the USB ports, inputs, outputs, RS485, MOSFET channels, stepper-driver connections and configuration jumpers. Also embedded in the [[pibot_cnc_laser_series:v588_ultra:pinout_reference:start#pb588-video-tour|Pinout Reference]].
  * [[https://www.youtube.com/watch?v=l1j_mVtbJDk|Independent Hands-On Review — CNCWOODSHOP (5:28)]] — real-workbench overview and V4.96 Pro comparison. This video uses a pre-production review unit; current product specifications, purchase options and Wiki instructions take priority.

**Important:** FluidNC signal assignments can be changed in YAML. Use these videos for orientation and follow the current Pinout Reference, test YAML and machine-specific wiring instructions for final setup.
