Cobra 4 keep stitching?

Thanks guys I will take some pictures later today and a video. It is a brushless servo so I guess I can stop looking for the clutch:)

A good rule for fault finding a engineering problem is to scribe a mark on both the fixed part and moving part before you turn anything, that way you can always go back to the same original position,...

 

This is a super technique!  A utility knife makes a tiny mark that’s little more than a small scratch.  A more permanent mark can be made with center punch, carbide scribe, or even a small carbide burr in a dremel. 

Even something as simple as a Sharpie mark (if it won’t me smudged off), or fingernail polish, or a paint pen will provide a reference without permanent mark.  Degreasing helps these marks stay in place.

I had a similar problem.  I talked with a  Leather Machine tech at the Pendleton show and he showed me how to adjust a little piece inside the servo motor case. Fixed it easily. Give them a call or send a message to Cobra Steve. -- John
