The ramps X Clone as X1 works beautifully But I am having a strange problem: If you look at the code  ,there are two different parts. One is for simple move of a srepper the other is for a simple acceleration. The simple move with X and clone X1 work. Simple Accel clone X1 does not.While X fulfills its command to move to the right side by a thousand steps  , X1 does not: It moves 300 steps to the left (approx) and then 700 steps to the right.!! Can anyone find the bug? The code link is below. Thanks
