Your CNC is a complex system of components. It's a best practice to do a simple walk-around-pre-check whenever you begin a new project. Here’s a checklist I use.
- Is the countertop or table the CNC sets on flat?
- Are electrical cords grounded and in good condition?
- Are all belts clean, free of dust and debris and properly tightened? Are there missing teeth, any cracks or excessive belt stretch?
- Are the stepper/servo motors securely fastened to their mounts?
- Are all screws, bolts, and nuts tight?
- Is the Controller clean and dust free?
- Are all the Stepper motors and Home Switches securely connected?
- Are there any broken or missing zip ties?
- Is the power supply connected to the controller?
- Is the USB cable connected to the controller?
- Is the wiring segregated and properly secured to minimize electrical noise?
Gantry and X Frame.
- Does the Gantry roll easily on the X Frame rails?
- Are the rails and bearings clean?
- Are there any broken or chipped Rail supports?
- Are the bearings adjusted snug to the rails so that they only turn when the Gantry moves?
- Are the idler bearings and belt pullies in proper alignment?
- Inspecting the Z Carriage.
- Is the Z Carriage trammed to the spoilboard?
- Are the bearingss snug to the rails?
- Is the router firmly secured in the spindle mount?
- Is the router collet clean and free of saw dust and debris?
- Are the router bits sharp?
- Are the spoilboard, clamps and clamp hardware in good condition?
- Does the workpiece lay flat on the spoilboard? Is it securely fastened?
A few minutes of inspection can save you from wasting time and material when machining your projects.
