I have debugged tons of stuff with this but at this point I cant really debug any further, so can someone give my code a quick look over and hopefully spot an issue? feel free to ask any questions regarding what has been debugged or what any certain chunk of code is trying to achieve, i will try to post as much relevant info as i can below the code:

Ive debugged a ton of stuff,not including all the console errors I’ve come across (which i have eliminated entirely), some of which includes the edge points, which I have visualized using basic box meshes, and the corner points, which I have also visualized using the same method, i have also tried creating simpler meshes with the arraymesh I set up to create, and as you can see I added a small wait before it finalizes and appends the mesh incase computational time was a factor, now I have gotten to the point where everything looks fine and i believe it honestly should work yet it doesnt and there isnt a single console error, please help it would mean the world to me.
here are the lookup tables I used, I do not know enough about marching cubes to know myself if this is the problem, which is why I’m hoping someone more experienced can help me out on this:
