$110 & $111 ( X & Y Max Rate ) are set to 1200mm/min try changing to whatever the max of your machine is and reduce til you are comfortable with the speeds.

1000 mm/ min is very slow for a Sculpfun S9.
6000 mm/min is the max rate ($110, $111) for this other user’s S9.
I checked today the console and its back to this

Grbl 1.1f …
If the engraver is set up properly and on a stable bench you should be able to engrave at the speeds you’ve selected.
Engraving at speeds above the max rate setting can have some strange effects. Your speed and power settings may need further adjustment after your change to Max Rate.
Settings and their definitions here if you’re interested:
## 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).

You can find a full table of all recommended settings for an S9 at the end of this page:
There are quite some values that are off standard. $120 and $121 are also way off, which leads to slow movements. Set them to 500 or 750.

On your Fill Layer, if you select an excessively small dot size setting you can consume more time than you need to.
Please double click on the Fill Layer in the Cuts / Layers window. I’d like to see the Line Interval (mm) or Lines per Inch settings.
Did you perform the Interval Test in the Laser Tools menu? This will aid you in getting the best working line interval setting based on your laser and your current focus.

What kind of material are you engraving?
1/254 of an inch is just under 0.004" That’s pretty optimistic.
Please retest to see if a line interval of 0.1500 mm produces adequate results. it won’t travel faster but the job should complete much sooner.

Just 3mm ply and maybe some slate coaster now and then, will give it a go.
