Got mine going! 🙂
Was just beeping and wouldn't budge at all in either direction.
FW Version 3.2.3 (updated yesterday)
Took it off the mount, looked at my old notes that I kept.
Hooked it up with the USB cable through ASI Studio, (newest version is out) and connected to "ASI CAP",
selected the EAF and powered it up thru this software.

Noticed that I didn't have anything in the "Set Maximum Steps" dialog box.
Entered the value of 19,000 and voila!
I was able to move the autofocus via the "Coarse Steps" or via 
the "Fine Steps".
Reset the "Current Position" to my own setting of 7705 (for my Z61) and all is good!
Mounted it back on the telescope and it works great.
Will run the curve next time our skies are clear, (west end of Lake Ontario).
Included a screenshot using the "ASI Cap" software.
Hope this helps!
Will add the screenshot in another reply....
