Can anybody offer any suggestions on anternative to diamond cup for 180mm floor grinder? I’m after something less harsh for fresher screeds that need a lighter sand..

yes type ones to attack the glass paper sheets
glass paper is not good?
I prefer glass paper in comparison to tungsten carbide

Not sure what you mean by tungsten carbide pads? Id like a durable solution, do the copper discs last a while or do they wear fast like a paper disc does

those in copper are tungsten carbide.
they last longer, but the cost is also higher.
mine does not do a good job, maybe I took a too big degree.
I prefer sandpaper, but I could be wrong I do not use it much.

Perhaps I should try some 60 grit sandpaper first and see how that goes

I've used sandpaper on fresh ones with success Andy. I've only ever had alpha hemi hydrite ones though if that makes any difference. Interestingly, I've just seen a statement from Knauf, who supply the raw material for the ones I get, that the alpha hemi ones mayhew easy screed do don't need sanding!

Well, I'd take that with a pinch of salt ey.
I've come across all sorts all more so lately cement based screeds that need sanding, and if your sanding within the first couple of months they all sand pretty easily, the diamond can be over kill for them.
