Where can I find the $$ chart for GRBL settings? I want to check my max speed that my machine is set to in the Grbl settings? It will be a $ followed by a number setting but not sure which one
You can review these in Edit->Machine Settings if you’re not familiar with the individual settings.

You can start here. Word of warning … Don’t change anything until you are sure (no hesitation) that what it will do is what you want. Playing what-if is not a good idea.

## Getting Started
First, connect to Grbl using the serial terminal of your choice.
Set the baud rate to **115200** as 8-N-1 (8-bits, no parity, and 1-stop bit.)
Once connected
you should get the Grbl-prompt, which looks like this:
```
Grbl 1.1d ['$' for help]
```
Type $ and press enter to have Grbl print a help message. You should not see any local echo of the $ and enter. Grbl should respond with:
```
[HLP:$$ $# $G $I $N $x=val $Nx=line $J=line $SLP $C $X $H ~ ! ? ctrl-x]
```
The ‘$’-commands are Grbl system commands used to tweak the settings, view or change Grbl's states and running modes, and start a homing cycle. The last four **non**-'$' commands are realtime control commands that can be sent at anytime, no matter what Grbl is doing. These either immediately change Grbl's running behavior or immediately print a report of the important realtime data like current position (aka DRO).

Yeah, I printed that one and carry it arround. The one I suggested has more why-for in it.
