This is the very same issue I experienced when migrating my application
from R3.13.9 to R3.14. I concur with Ron about the undocumented change
in parameters. On dropping the 'Number of axes' parameter, it all sprang
into life! It took me a couple of days to track it down.

Ian

Ralph,

If you look at the "Known Problems" from R5-4 to R5-9 on the motor
record web page;

http://www.aps.anl.gov/upd/people/sluiter/epics/motor/index.html

you will find the following;

In other words, the 2nd argument was eliminated.  That is probably your 
problem.
