After having my machine down for a couple weeks, I'm happy to say I have fixed the robotics. I'm busy stitching on this king size quilt. The X-axis gear was out of whack on the robotics, and as soon as I fixed that, then the Y-axis gear went out of whack. LOL! At least now I know how to fix them if the problem ever happens again.
You can see the quilts lined up in the background that are waiting to be finished! I'm way behind, so I'll be busy, busy the next few days.
