I agree with taking it back to dealer with examples of problem designs so they can see exactly what is going on. I bought my machine earlier in the year, 500E demo floor model and have not had issues like this. Also join the Janome 500 facebook group. The women are great when trouble shooting problems. Another thought is if you have not take dealer user classes then do. They are worth the time if you are not use to embroidery and using the machine.
