Why 90% of People Wire Emergency Stops INCORRECTLY (Don't Make This Mistake)
Learn how to ensure your CNC machine is properly grounded with this simple and effective grounding test. In this video, we will show you a DIY method to verify the low resistance ground of your CNC cabinet using a multimeter, which is an essential step in maintaining machine safety grounding. We will also discuss the importance of a ground bond tester alternative and how to use a PSU multimeter for grounding measurements. Additionally, we will cover the basics of CNC electronics, including the use of a GX16 connector, and provide tips on how to achieve a low resistance ground, which is critical for industrial grounding measurement and electrical safety. By following this CNC electronics tutorial, you will be able to identify potential grounding issues and take corrective action to ensure your CNC build electronics are safe and reliable. This video is part of a series on CNC electronics basics, and it is aimed at those who are looking to improve their knowledge of CNC cabinet wiring, ground star point, and PSU voltage test. Whether you are a seasoned CNC user or just starting out, this video will provide you with valuable insights and practical tips on how to keep your machine safe and running smoothly, as demonstrated by steelknightcnc.
✅ What you will learn:
How to mount and use a GX16 panel connector wired to your cabinet’s ground star point
How to set your PSU (voltage & current limit) for a safe resistance test
How to measure voltage and current, then calculate resistance (R = V / I)
What resistance numbers are acceptable and how to interpret your results
Safety tips to avoid live-circuit hazards during testing
If you’re building or maintaining a CNC machine and want to verify proper grounding safely and affordably, this step-by-step tutorial is for you.
