I am trying to cut some Glasses out of some bass wood and the laser initiates at the Corner End of the Frame and cuts through the finish product, also most all the way through. How do we get that to stop? 2nd - Can I add a g-code funtion to turn-off the laser after it homes when completed? Right now its until I change COMs or flip the switch. What I have done to try and fix the 1st issue is below, after my console info. I have gone through a ton of different LB forum Posts, GRBL github posts linked by Ox or JohnJohn but everything I have attempted has not worked.
Posts I am referring too:

Creality 5W Falcon Laser Not Discoverable with Mac OS, Firmware Update Issues, & More → for firmware issues
Newbie here with lots of questions - #9 by JVL
Referring to the picture below, the Red Line is what is cutting through the Frames.
Now my equipment is as follows:
I bought Lightburn last night and installed 1.4.01 on Windows10 22h2
Creality Falcon controller with a 10w laser on a Ender 3v2 chaise(220x220).
I am currently using a USB 3.0 10’ extension cable to the USB A-USB C cable until my 12’ USB A to USB C comes in from Amazon this weekend. I might be adding a camera sooner than later as well.
I have the g-code for the frames at the very end of this post!
My console notes from the second I connect it to “$$”
Waiting for connection…

What I have done to this point:
I upgraded the firmware on it(that fixed the laser being on at 100% full time from the second it got power until it went into standby mode) and had to do the $3=3 to reverse the polarity due to the firmware. I did the $32=1, Changed both the $30=1000 to $30=255 and did this in the Device Setting at S-value max
This last Attempt I did, I even broke the frames into 3 layers thinking the transition of each layer would be a trigger for stop and start, but that didn’t work.
Any help mainly with the laser burning the finish product is my #1 concern then the laser homing and staying on is secondary!!
Thanks for any and all help!
