Brush not working for me + Is there a discord?

[Beavermon]

This is what i'm typing and the brush only displays a sand sphere. What am I doing wrong?

There is an extra space in your command
//brush sphere 7.5 sand,70%sand,30%sandstone (gravity=false is already default too)
also you probably want to leave the first sand out completely (its the same as 170%sand,30%sandstone)
