ToDo

• Light bar:
  • Needs to be connected to relay, then powered from the 24VDC machine power supply.
  • Relay needs to be connected to Raspberry Pi I/O for the OctoPrint Environment plugin to control
• Credentials for OctoPrint and Pi need to be put onto machine physically,. and/or shared with Amelia Meyer
• MMU2S filament spools need a better holder. Maybe something like a retracting winder?
