The needle will break, and they are made by Schmetz. I have no idea why but they stitch much better thru a line or area where the stitches run over them selves multiple times.
The needle is gold, maybe the tip is titanium not sure but they work really good.
Hope you get your problem worked out.
I have never used titanium needles because the risk of damage to my machine is not worth it to me. If I get a nest or tangle I prefer a needle break. Just my preference.
I have always used Schmetz or the Janome needles with all of my Janome machines and never had this problem.
I am suspecting that the design is the culprit and wonder if something happened during the conversion from PES to JEF. (Jim I just remembered that I did convert the file).
Still, never had this happen before. :(
