I have been sewing since I was a teen, and currently own a Brother PC6000 – which I loved until recently. I’m having trouble with the needle jumping up and down when I first start sewing, without the material advancing. I have to manually move the material just a bit and try again – sometimes the machine will engage and sometimes I have to do this several times. VERY FRUSTRATING. I have done everything the manual instructs, to no avail. This mainly happens on thinner material. And then, to make matters even worse, when the machine actually engages, it literally gathers the thin fabric. And sometimes the upper thread will break for no apparent reason.
Can anyone tell me what is wrong – is there anything I can do to correct this?
