Can you post a picture so we can know what you mean, poor stitch out can be how it is stabilized, i could be the thread shredded some while you weren't looking, It could be the needle. It would help if we knew stitch count of design what and how much stabilizer used, what type thread was used, needle used. AG are well digitized so without a picture it is really hard to tell what went wrong. I have been doing embroidery for 2 years and find most of my problems tend to be improper stabilization. Its almost always user error and less likely the machine or the design
