Woodworking Machine Troubleshooting & FAQs

Vacuum loss and workpiece movement are the two most common CNC router and nesting faults, usually linked to seal wear on the table zones, incorrect zone selection for the panel size, or worn gaskets. Cut-depth and tool-offset errors point to tooling setup rather than the vacuum system.

Glue-bonding failures are most often a glue-pot temperature problem - too hot, too cold, or an inconsistent heat-up cycle. Feeding problems and poor trimming or scraping quality usually mean the pressure rollers or trimming units need adjustment. Confirm glue temperature first, since it's the fastest fix.

Hole misalignment and tear-out are usually caused by incorrect fence squareness, insufficient pneumatic clamping pressure allowing the panel to shift, or tool zero-reference drift. Inaccurate drilling depth is almost always a tool-reference calibration issue.

This guide is for first-level diagnosis only. Basic checks such as fence alignment, glue temperature, and clamping pressure can often be done by trained operators. Anything involving hydraulics, electrical or heating circuits, or structural adjustment should go to a certified technician - contact Caple Service with your machine model, serial number, and fault description.

Your machine model and serial number, a description of the fault, the exact alarm or error message if one is displayed, a clear photo of the machine nameplate, and only if it can be taken safely, a photo of the fault itself.
