i typed the command but i donno how to use it. what do the 2 numbers in the corner mean?

The high speed, the color indicates who has the highest speed. (blue-uke, red-tori)
I think the top one is the highest speed, and the bottom one is the current highest.

ok how do you know how fast a joint is moving?

/sm 1 shows high speed, no command tells individual joint speed.

oh
