Maintenance

Regular maintenance ensures the longevity and optimal performance of your AtomStack C4 Pro.

• Dust Collection: Utilize a dust collection system to keep the work area clean and prevent debris from affecting mechanical components. The machine's design helps keep internal mechanics protected from dust.
• Limit Switches: Exercise caution when adjusting or cleaning around the limit switches. These small metal components are crucial for machine operation and can be damaged if handled roughly. Consider covering them during heavy-duty operations or when cleaning.
• Lead Screws: Periodically inspect and clean the lead screws to ensure smooth operation and prevent slippage.

Troubleshooting

• Lead Screw Slippage: If you experience issues with the lead screws, such as slippage or inconsistent movement, inspect the connection points between the lead screws and the stepper motors. Ensure all connections are secure and free from debris. Adjustments may be necessary to reduce friction.
• Damaged Limit Switches: If a limit switch is damaged (e.g., the metal spade is broken), it will need to be replaced. Handle these components with care during assembly and maintenance to prevent damage.
