I'm having trouble with my wifi-Nfocus2.  My understanding is it uses the Nstep driver (that's what connects); however it ends up with a runaway condition where it never stops moving.  From what I can tell, the movement is commanded, but it doesn't ever check to see what happens as if it's a relative focuser so it never shuts off.  It also doesn't allow me to 'abort'.  I have to go out to the box and use the hand controller to stop the motion.  

Does anyone use one of these and know how to set it up?  I'm sure Gene will chime in with how to fix it.

Thanks!
