Instead, respond to the thread on the WEBSITE by clicking here: http://www.amayausers.com/boards/cgi-bin/ultimatebb.cgi?/topic/1/1466.html I have a 2010 XTS and as it was sewing the stitching seemed to speed up and hitting the needle case or arm as if the stroke became longer. Now it will start and slam up and down and needle eventually stays down. I have video of this happening and pics of the needle in the lower position. It happens on all needles. OS gets locked up when I start this machine. Already reinstalled OS 10 with no change. Checked Z motor and it turns fine. I find no resistance to cycling the machine by hand. No obstructions and everything lubed. Can't see any broken parts or gears. Before it became unrecognizable by the OS, I did get Z axis error. Any help would be appreciated. I am in Northwestern Michigan and would also appreciate info on any techs in this area.
