1) When you ran first run wizard did you choose "ultimaker2" or "ultimaker original"?

2) Did you install a new marlin?

It looks to me that your steps/mm is wrong such that it is moving half the distance it should be. Try moving exactly 10mm and see how much it moves.

There are software endstops in Marlin meaning it will not go farther than 20.5cm. But if the steps/mm is off by 2x then this explains what you see (only goes to the middle).

2.This problem has been resolved

3.I have found that short-synchronous belt wheel dirty, causing the loss of synchronism. Cleaning, now can to work.

Thank you
