# Maintenance When using the CNC function of the Snapmaker Artisan more frequently, I would recommend — besides the officially recommended maintenance — paying attention to a few additional, practical points. {% hint style="info" %} Official Snapmaker Artisan Maintenance Recommendation:\ {% endhint %} The points below are intended as **optional additions**, based on regular CNC use. They focus on areas that are usually not addressed during routine surface cleaning. *** ### Cleaning the Linear Axes (Rail Area Under the Cover Strip) With continued CNC use, chips can accumulate directly on the linear rails beneath the metal cover strips of the linear modules.\ To clean this area, the metal cover strip must be carefully lifted or removed to access the rail itself. #### What to be aware of * Chips trapped on the rail cannot escape on their own * The buildup is not visible from the outside #### Good practice * Power off and unplug the machine before any inspection * Keep track of the orientation and mounting points of the strip * Clean the exposed rail gently using: * vacuum * gentle compressed air (always dry air) * Reinstall the cover strip carefully after cleaning *** ### CNC Module Cooling Path The CNC module is air-cooled. Over time, fine debris can accumulate **inside the airflow path**, particularly around the ventilator and internal air channels. #### What to be aware of * Debris can settle on or near the ventilator blades * Reduced airflow can lead to higher internal temperatures * Changes in cooling performance are not always immediately noticeable #### Good practice * Power off and unplug the machine before any inspection * Check the ventilator area and accessible air paths for buildup * Remove debris from ventilator openings and internal airflow paths using: * vacuum * gentle compressed air (always dry air) *** ### Tool Holding & Collet Cleanliness Tool holding components are handled frequently and can collect debris over time. #### What to be aware of * Dust or chips in the collet can affect tool seating #### Good practice * Clean collets and collet nuts occasionally: * wipe with a clean cloth * use a soft brush or gentle, dry compressed air if needed *** ### Cable Routing & Visual Checks This particularly refers to the rotary axes. #### What to be aware of * Rubbing or pinched cables * Tight bending points * Loose connectors #### Good practice * Perform quick visual checks from time to time * Ensure cables move freely without tension --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://miwicnc.gitbook.io/miwicnc/maintenance.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
