The serger is a White Superlock 534, and the feed dogs appear to be going in the wrong direction, and fail to advance the fabric. Foot tension, needle function and cutter are working well. It seems like a simple problem and occured after oiling and running a perfect sample.

Hello Keith,
No reason why the machine is not feeding the fabric through unless there is not enough pressure on the foot or the very worst is that the timing has slipped.
