Hey Tom, hey all, > [@TMToronto](#): > > To ground the machine, I have seen in numerous CNC forums the practice of bolting a heavier gauge copper cable to the main metal chassis of the CNC (the 1F machines have many locations with bolts/screws), and taking this to a common earth ground point. The question whether grounding the chassis comes up from time to time, we had this in [Voltage Present](https://forum.onefinitycnc.com/t/voltage-present/8599/5) the other day. Did you see what just was the cause of the issue in: > [@Onefinity Controller Stopping Mid-Program (solved: EMI / Static Build up)](https://forum.onefinitycnc.com/t/onefinity-controller-stopping-mid-program-solved-emi-static-build-up/9041/5): > > I think I need to ground my table! > [@Onefinity Controller Stopping Mid-Program (solved: EMI / Static Build up)](https://forum.onefinitycnc.com/t/onefinity-controller-stopping-mid-program-solved-emi-static-build-up/9041/6): > > Yup. Table is grounded. […] Everything doing what it should now! Seems [I was right then](https://forum.onefinitycnc.com/t/voltage-present/8599/8) 🙂 I think this is to note also: > [@Surprise benefit to grounding your spindle](https://forum.onefinitycnc.com/t/surprise-benefit-to-grounding-your-spindle/1734): > > I wired my spindle with a proper shielded 4-conductor cable. The ground wire is attached to the casing of the spindle. The other end shares a common ground with the VFD and Onefinity controller. I found a surprise benefit is that if I forget to attach the probe magnet to the collet, the probe still registers through ground when touched and works normally- saving the tools from any damage. (It’s scary how many times I’ve forgotten to attach the magnet already!). --- _[View the full topic](https://forum.onefinitycnc.com/t/longer-motor-cables/1206)._
