The $12 Homebrew clone of it, yes. The $250 real one, no. 
It has to be run and detect the stops automatically. If that's not working, then there's a mechanical issue somewhere.
I've tightened the clamp as far as I dared. The motor is mounted snugly and it's not binding, an improvement on the first time I tried it. The motor keeps running when the stem hits the stop. The stem will move when I run the motor, as long as I don't hit the stop.
I decided to run the motor from an initial stop out position and then travel it out toward the other stop position. I was using the CPWI focuser control and a game controller and I was keeping an eye on when the stem stopped. I noted the number at the start. I noted that it hit a max number then started from zero before hitting a value at the end:
+ 8800 = Travel out position
+ 59995 = Max value
- 21300 = Travel in position
Arbitrary values based on whether the stem is turning toward the positive sign or not.
I got a value of 43261 when I trained the scope on an object 1/4 mile away it went into focus. I supposed I managed a rough calibration. Good enough, I suppose.
I also put in in a ticket to celestron about it. I'll see what they say.
