I have a Brother Pe-770 why does the upper thread keep breaking !!! urg! I re-hoop use every stabalizer known to man, I changed my needle. I haven't had this machine for about a year and EVERY Design needs re-threaded at LEAST 2x every design !! Im soooo Frustrated !!!! urgh !! can someone tell me what to do ! Its been in the shop 2x and Im about to toss it out a very high window !!!!!!!!!! why can't it just do a design start to finish !!!!!!!!!!!!!!!!!!

Try this - use a larger needle.  If it is shredding, it is definately too small a needle.  I am a living, breathing example of learning this the hard way.  I talk about it in my blog, Fran, in a small shop in Surprise Arizona (just northeast of Phoenix) told me and I did not believe her.  When I tried it, I was astonished. 

You don't say what you are embroidering.  That will make a difference.  My 3, very reliable and knowledgeable, technicians could not answer the breaking thread question.  I do a lot of words on hankies and that was an issue as well.  Are the designs dense?  If you hear the needle pounding through the material/stitching, it is dense and/or a dull needle. 

Let us all know what happens with this.  Email me if you want to talk, I have been where you are and I understand.
