Hi
I sure hope someone can help me out here. I have owned a commercial machine for 4 years. Toyota Esp 9000. I have a design that I have stitched thousands of times. The problem is about 5 months ago I noticed the design was stitched out and having a loose thread that was unraveling. I took my machine in to Pantograms for a tune up. THey saw nothing wrong with it. I have notice with running stitch that the bobbin thread isnt catching for 12-20 stitches. The rest of the design seems fine but the fact that those intitial stitches dont catch makes design come apart.
What is it that could be going on?
I have adjusted all thread tensions, changed needles, check all thread paths, checked made sure it has lock stitch on. replaced the bobbin case.
Also the bobbin tension is very erratic. Like for example the bobbin thread was showing on top of the design and the bobbin thread was already too tight.
Please help I have a heap of orders piling and I am at my wits end.

Sounds like your hook timing is off.

It could also be the type of material you are sewing on. Some materials need needles with special points. It it is a thin but dense material, you might try a sharper, smaller needle that can penetrate the material easier. Many embroidery machine needles use a ball point or modified ball point, great for knits, but not for some other materials.

Try slowing down your inching speed, however, if you've done the design before without issue, I agree with Art, your hook timing may be off ever so slightly.
