Hey Mike,

there exists a **search function** in this forum. Using it would have allowed you to find the answers yourself,

- e.g. [here](https://forum.onefinitycnc.com/t/configuring-a-custom-vfd-and-spindle/2397/31) for the VFD ModBus settings,

and

- [here](https://forum.onefinitycnc.com/t/speed-control-dial-does-nothing-on-vfd-solved-vfd-wiring/12831/1) to make the speed dial on front panel functional.

Note that a [VFD](https://en.wikipedia.org/wiki/Variable-frequency_drive) is a device that is meant to be [enclosed in a cabinet](https://forum.onefinitycnc.com/t/proper-grounding-how-have-you-grounded-your-frame/12331/22).
