I'll give that a try. How do you like the Hydropharm mover? They are pretty cheap so I was thinking of getting one. Mine Is a Light Rail 3.5 Intelidrive. It takes about 30-45sec to travel 3ft 3" and then it has an adjustment knob that can delay it up to a minute at each end of the rail. I read that yours takes 20 min to travel 4ft?
