MM infinites

How do you setup and do the MM infinite thats with jab jab than the fp? if you do not know what im talking about its kinda like IM infinite.

The megaman infinite is kinda easy. It’s just the setting up part which is the real problem. Yeah it’s like:
j.lp, j.lp. j.hp, Repeat

The timing on it is slow. You should be coming down on the second hit. When you land the third hit (the buster hit) He should hit the ground right after it hits so then you can jump up and start all over again.
