Desktop CNC Safety Monitor

Non-invasive monitor for enclosure door, spindle state, and emergency stop. Non-invasive monitor for enclosure door, spindle state, and emergency stop.

Components

  • MCU + door/interlock/emergency-stop monitor
  • Regulated low-voltage bench supply
  • Emergency stop or safe fallback input

Build steps

  1. Inventory the board, actuators, sensors, and power rails listed for I04.
  2. Build and inspect the low-voltage wiring against the supplied connection diagram before connecting actuators.
  3. Flash the firmware, run the startup self-check, and record the printed board and firmware version.
  4. Calibrate the sensors and limits, then run the acceptance tests at the lowest safe energy level.

Test and expected result

Verify interlock state transitions without controlling hazardous machinery.

Safety and limits

Monitor only; do not bypass or control hazardous machinery.
