OK, so I have found some posts/threads to start working on getting the laser up and working properly.
Laser Specs:
And plugged into the SKR Pro V1.2
I have found that Ronald had the same issue with light burn so thankful for his thread and experience.
So, I set up my device as a Marlin, shown below. I exported the gcode after following the comments from the above thread. Commands are “Inline” and I made the S factor 1000 and Fast Whitespace Scan to 1600mm/min. Gcode script to include M3 I at the start.
I drew a simple square to cut out with the below settings. I saved the Gcode as per below and plug the SD card into the TFT for printing.

Result
It did not cut through all the way. So I will try with 2 passes

In the end I did 8 passes to almost cut through.
Next, I slowed the speed to 110mm and up the power to 85%. @ 2 Passes
Results: Instantly better, only 2 passes!!
Thats about all I can do for the day. Will definitely be doing some more exercises tomorrow now that I have been able to cut through.
Heading into watch the NRL, Broncs vs Sharks, should be a bit of a match as Origin was on Wednesday and some of the main stars are out.
