Limit switch is mounted on CNC router machine or moving objects, when the object approaching the stationary, the limit switch breaking or disconnection. ![CNC router limit switch]() Limit switch is one of the most common accessories of CNC router, a small part, but the function is great. Many customers don't know how the limit swith work, and some customer may inadvertently touch the limit switch to make the machine work wrong. Limit switch is mounted on a relatively stationary objects or moving objects, when an moving object approaching the stationary, the switch breaking or disconnection. The limit switch is the origin of the CNC router,it can prevent the working exceeding the range of engraving to produce failure. Therefore, there is two points to lead to the wrong working, customers can analyze and solve depending on the situation arising. 1\. The carving path beyond the engraving range:to set the parameters of soft limit switch in the software . 2\. The customers in the using of wood cnc router should design a good and reasonable carving range, set the appropriate software parameter; should always check the limit switch is flexible or not. So the limit switches are one of the indispensable accessories, customers should be more carefully to check the performance of limit switch, in order to avoid fault,fail to reach the limit of the action . The performance level of the limit switch also protects the CNC router from damage caused by the fault. ### Share This Article With Others ### Further Reading #### Stepper Motor Driver Solutions for CNC Woodworking Machine 2016-01-14[Prev Post](https://www.stylecnc.com/user-manual/Stepper-motor-driver-solutions-for-CNC-wood-router.html "Stepper Motor Driver Solutions for CNC Woodworking Machine") ### How To Maintain A Fiber Laser Cutting Machine? 2016-01-24[Next Post](https://www.stylecnc.com/user-manual/Daily-maintenance-of-fiber-laser-cutting-machine.html "How To Maintain A Fiber Laser Cutting Machine?") ### Related Guidance [](https://www.stylecnc.com/cnc-solutions/how-to-choose-right-cnc-router.html "How To Choose The Best CNC Router Machine?") 2023-10-075 Min Read #### [How To Choose The Best CNC Router Machine?](https://www.stylecnc.com/cnc-solutions/how-to-choose-right-cnc-router.html "How To Choose The Best CNC Router Machine?") Most people only consider the low cost when choosing a CNC router machine. However, we really need to consider both the price and applicability. If you buy a CNC machine at a cheap price, but it is not suitable for your work, then it's just like a pile of scrap iron.

Hourly pricing works best for custom and unpredictable jobs, while per-project pricing suits standardized products with repeatable workflows. Most profitable shops use a hybrid approach, applying flat rates for catalog items and hourly billing for custom work.

Most CNC routers and laser machines pay for themselves within 6 to 24 months, depending on machine type, utilization rate, and business model. Hobby-grade machines under $5,000 often break even in under 6 months through custom product sales. Industrial fiber laser cutters and full-size CNC routers typically recover costs within 12 to 18 months when operated at 60% or higher utilization. The key variables are production volume, pricing discipline, and consistent order flow.
