not sure which forum to post this so I went general
I have a 6" arbor- it is older than the rocks I work on, but it still runs
I am trying to take small grooves out of slabs- I like using sanding discs but wondering if there is a better way
I use a coarse carbide and work my way finer- but l would like advice on the grit size on the discs if discs seem reasonable
depending on the groove, I kind of do something like 80-220-600-1200-8000-50000

How small of a groove? A little more info and maybe a picture would help. What are you doing with them?

grooves are usually very small
I'm a little hesitant to upload pictures because I dont want to get a cloudinary account

Are grooves saw marks? I don't do anything with saw marks until I've made a preform. I use the grinding and sanding wheels to remove them. Another alternative is a flat lap mounted on the end of the machine.
