AC Servo Motors and FogBuster Mist Coolant - DIY CNC Mill Upgrades

Explore the process of upgrading a DIY CNC mill with AC servo motors and a FogBuster mist coolant system in this comprehensive 41-minute video tutorial. Learn about the advantages of servo motors over stepper motors, including improved throughput, repeatability, and cut quality. Follow along as the instructor demonstrates the installation and tuning of DMM AC servo motors, explaining how their closed-loop encoder feedback eliminates resonance and movement anomalies. Discover the benefits of Minimum Quantity Lubrication (MQL) systems and how to set up the Mini FogBuster for efficient, mess-free coolant application. Gain insights into compressed air setup, relay and flyback diode installation, and the importance of preventing aerosol generation in enclosed spaces. Watch a test cut demonstration and learn how these upgrades enhance CNC mill performance, including faster rapid movements.
