Snapping thread

[UKRay]

I have a brand new Highlead GC0618-1SC fitted with a servo motor. As long as it is stitching fast and straight it works fine but the minute I slow down the stitching, try to turn a corner or put the thing in reverse I risk breaking the thread. It doesn't do it every time (that would be too easy!) but whilst making a simple tool roll with twenty tool slots I had the thread break fifteen times. Another complication is that the servo motor has a 'computerized' control panel. When I slow the stitching down at the end of a run I run the risk of the computer control shutting down giving me an error reading. I then have to 're-boot' the machine by turning off the power.I purchased the machine new and am starting to wish I'd never seen it. Anyone got a clue what is happening here and how it might be fixed? I've got the engineer who sold it to me coming soon but I want to have a better idea of what the problem is before beating his head with it...Can anyone help? Ray

hooo boy electronics

if it is the computer on board -- it might be toast

electronics have two failure rates -- right now (in warrenty) or 20 years from now (when the warrenty is so out of date it doesn't matter anyway)

can you take it back and get a different one?
