  4. Push the E-stop button.
  5. Turn the power OFF with the ON/OFF switch found behind the machine.
  6. Disconnect the main power cord from the receptacle.

    Dangerous voltages continue to be found in the electrical panel when the ON/OFF switch is set to OFF. Disconnect the main power cord from the machine while maintenance is done. Failure to do so can cause electric shock.

  7. Turn the vacuum circuit power OFF with the ON/OFF switch found on vacuum control box.
  8. Disconnect the power cord from the the vacuum circuit electrical enclosure.
  9. Wait until the build chamber, build platform, and hot ends are at room temperature.
