well--dang---after getting the regular needles I was still having the skipping issues, ditto with #18--so broke down and called Gammill Rep and he wasn't able to help that much--suggested it may be either encoder issues or timing. So I drug out the computer for the YouTube video on timing, watched it at least a dozen times, got the timing tool out and timed it--took a while cause this is first for me. STILL skipping. and to time you have to have needle bar height right so that's not it either. So then started with encoders. Someone on Gammill FB site suggested trying with manual instead of stitch regulator AND that worked fine--so must be encoders for SR. of course it's labor Day weekend and the regular tech may/may not be available. I'm totally bummed--any Gammill owners have an idea for me to try??
