Hey Kerry,

you did not tell which controller you use, the Masso G3 or the Buildbotics-derived Onefinity controller?

Is this video still not deleted???

This video tells you to attach the spindle without PE wire, which is **extremely dangerous.** I hope you did not follow this bad advice? If so, I would buy or make a new spindle cable immediately. See links below.

For the VFD settings, have you read and understood the VFD manual? **I hope you don’t use settings from youtube videos without knowing what they are for!**

When using the search function of this forum, haven’t you found this?

- [Problems installing Huanyang VFD and spindle on my Woodworker](https://forum.onefinitycnc.com/t/problems-installing-huanyang-vfd-and-spindle-on-my-woodworker/13464/5)

It mentions a few settings that you should know to which values you have to set them.

The other thing is the “speed control source” and the “RUN control source” that should be set depending on which which CNC controller you use.
