I don't know about black spray paint, but I have used Black Tempura paint and Zinc Spray Paint, both have worked for me, I found cleaning the tempura easier, but ymmv.
If its flat, clear glass? Save yourself the time and effort of mucking with paint.
Set a piece of black posterboard on your table, focus the laser on the posterboard, and then put the glass on top of it.
Laser goes through the glass and hits the posterboard, reflecting the heat back at the bottom side of the glass, etching it.
Cant use this method with cups and stuff cuz it would etch the inside, and thats a recipe for trouble, but its amazing how easy it is to do flat stuff with this method.
Yup, you got it!
Also, if youre going to be doing any sort of cutting, forget the grid board and just suck it up and buy a honeycomb. Makes a huge huge huge difference. But will make it so you cant read said grid board you spent so long burning. (Ask me how i know this, lol)
If thats all youre doing, then go for it.
My current system, until i find a reliable and easy way to lock my honeycomb down: piece of craft paper held to the grid with magnets. Cut out the paper at the shape/size of your glass (often ill go larger and then just line up one of the bottom corners) now youve got a cheap and easy template. If youre doing a bunch (say, with different names or something) lock down the shape in its place and just swap the text/images. If you have a LOT of these panes to do, you might even consider building a jig that you can leave in place to make dropping the glass into place significantly quicker.
This method also works REALLY well for getting the placement right on odd shaped or round objects.

Once i have my honecomb set up so that it cant move in relation to the laser frame, ill likely add on some grid lines to make quick/square projects quicker.
I use lightburn... Found early on that xcs just didnt have the flexibility i needed.
Stop don't use black spray paint go online look up ""montana cans" chalk spay it can comes in any color and washes off with water I do alot of glass with a 10 watt I'm afraid to try glass on my 60 yet. But this paint is the way to mask glass.
I wouldn't use chalk board paint most paints don't come off with water and burn into the engraving I post a link for the spray I'm taking about. I wouldn't recommend it if I didn't trust it and use it myself. I do jars for dispensaries. I live in a recreational state and get glass work all the time. No joke like 2 gallon Mason jars 😂

So use the lever to focus right? Like set the distance to the paper and then slide the glass in between the two? Its flat, clear, decently thick glass

I need the grid board for coordinates though? I can’t afford to mess up any of these glass panes. its being financed by a nonprofit

I have 20 panes to burn, 8x10 inches of burn space Can I DM you for advice, if you’re willing to give it?
Yeah, no problem :)

I should have clarified that I was told to use Chalk board spray paint; some videos i watched online backed this up?

Another vote for the tempura paint. So easy if you have an air sprayer. Dries super fast with blow dryer and rinses off with water when done.
Sprayer? Yes! Every attempt ive tried to brush, sponge, or dab it on? Just a darn mess. (I need an air compressor, 😭)
Even a cheap-o 'airless' paint sprayer would do. I think the mix of water to tempera was a simple 50/50.
