Typically you won't want to constantly attack enemy creeps, and the animation cancel tactic is incredibly tedious and unless you're great at understanding your attack animation and how/when your attack will land you probably won't get the hit and you'll look like an idiot for wasting all that time for nothing.
I HATE the animation cancel tactic for two reasons:
1- If the creep is too low during your animation cancel, you'll miss the hit. Animation canceling is tricky to work with in that if you cancel it, but don't give yourself enough to reinitiate the attack to get the last hit, you won't get it.
2- If you stand still long enough, EVENTUALLY someone on the enemy team's going to take advantage of it and hit you.

If you REALLY want to use the animation cancel tactic, you probably aren't right-clicking the creep again after you hit S.
The way it works is you right-click the creep, press S, instantly right-click the creep again, press S, rinse-repeat until the creep is low, then right-click to kill.

What I normally like to do is constantly walk around (movement cancels auto-attacks, right-clicking back and forth to keep your character moving and my mind active so I don't fall asleep in lane, and if your opponents have hard to land stuns/spells they won't get easy harass on you), then when the creep starts to look low (on melee heroes) I walk up to it, then when it's low enough- right-click to kill and cha-ching! Gold. On ranged heroes you just wait for the creep's health to get low enough and time your shot so that the travel time for your attack will line up with the creep's health being low.

Its more of a habit thing. I like to do it but if its not working for you, then there isnt any reason you should do it.

haha u dont understand me.Thats the way i last hit , i use that way for about 3,4 years and suddenly its ****ed , cant use s , and not that i dont want to , just it doesnt work u know .. im not asking for advice , just how can i return that s last hitting

u know , some settings **** and that , i dont want another way to last hit :D

Its the gear in the top left corner. When you open it on the first page will be a series of hotkeys in the unit actions tab. There is one towards the top left that says "stop" thats the key you set to whatever you want and thats the key for spamming for last hitting.

i know , i know , everything is alright in that settings but still not working.I can stop hero with s , but cant spamm with it , got me ?

If you last hit by relying on auto-attack to continue attacking after you press "s", check that "auto-attack after casting" is set to YES, otherwise you sit like a lemon until you right click a creep.

If you last hit by alternately spamming s-Rclick-s-riclick, I don't know how you fix that.

Im pretty sure its a console where your game has it so that your game only registers 1 command per a certain amount of time so if you clikced stop, then for maybe .1 sec, no other commands can be issued. I forgot what was the console to do this but it should be pretty easy to find.
