Machine Monitoring

Open source software to monitor three machines in a pop-up factory:

• Laser cutter — OLSK Small Laser
• CNC router — OLSK Small CNC
• 3D printer — OLSK Small 3D Printer

Features

• Machine states — idle, pause, run, or job done
• Power consumption in watts
• Loaded G-code file name
• Job start and end times
• Summary table of completed jobs

Data from all three machines is saved to two CSV files: one for machine states with timestamps, and one for job details including job ID, G-code path, start time, and end time.

Architecture

The system uses an MQTT broker (Mosquitto) to collect data from modified bCNC (GRBL) and Printrun (Marlin) clients, which publish machine events to topics such as inmachines/cnc/state and inmachines/3dprinter/filename.

Requirements

• MQTT broker server (e.g. Mosquitto on Ubuntu)
• bCNC for CNC/laser machines running GRBL
• Printrun for 3D printers running Marlin

Project Files

• GitHub repository
• Machine Monitoring program
• Modified bCNC
• Modified Printrun
