gammill optimun locks up
 

have a gammill optimum with statler , the machine will lock up at time, will not move on the track in any direction. kind of shake machine and it will free itself up and continue stitching. any thoughts,? have checked rollers track any cables that might binding, no problem found.

Sounds like an electrical problem to me -- a loose connection somewhere. Maybe ask about it on the Gammill forum? http://www.gammill.com/forum/index.php

give the tech support a call--they are very easy to work with and have walked me through lots of weird things on my Gammill Classic Plus. Good luck.
