Yes it could be how you are moving the quilt.
Also could be the tension just needs to be different.
While you kept the settings the same, have you changed any of the variables?
eg. thread, batting type, different fabric, needle type/size etc.
Take both threads off and re-thread completely.
Sometimes while we think we have it threaded OK, there's something not threaded right!
Change needles ... try a different type and size.
Likewise thread ... try a different thread, and a different weight.
