My brother 780 is messing up AGAIN----I'm beginning to think it is MY ATTEMPT at digitizing (somewhat attempting)-----but it still does its old tricks even with "BUILT IN" designs----have done EVERYTHING---stabilizers, changed fabrics, using Floriani thread (the best as far as I am concerned), varied bobbin EMBROIDERY MACHINE threads, used Genie bobbin slider INSERT thingees, changed upper tension, threaded and rethreaded, taken bobbin case out and cleaned and reinserted, changed needles (Schmetz size 11 from WallyWorld and Joanns----Is threre a difference---same brand--same size--both EMBROIDERY NEEDLES), You name it, I have tried it...2 DIFFERENT repair persons----3 "CORRECT" bobbin cases, 3 different needle-throat plates--present needle plate was smoothed out by repairperson (the latest with 30 some years experience fixing UNFIXABLE machines of all kinds)---so guess I will take it back to see if machine becomes landfill or if there REALLY IS SOMETHING WRONG with the machine or if it is the operator!!!!!

Sounds like there might be some lint or a tiny piece of thread somewhere in the upper threading. Take some unwaxed floss and thread your machine with it. Do this several times. You might be surprised at what happens. Good luck.

I've done this before and it does actually help.

I FINALLY found some unwaxed floss @ Walgreens.
I will try it this evening.

Thank you...

I have always heard it is an upper issue when it messes up on the bottom and bottom (i.e. bobbin) issue when it messes up on the top. With that in mind, sounds more like a upper issue to me....

I also have a 780D Brother and was having some of the same problems although I didn't try all the things you have tried.
It turned out that it was the thread I was using. I cannot use Gutterman at all and can only use polyester thread. I also only use prewound bobbins and change the needle VERY often. Since I've been doing that...it has given me no problem.

If I stick to that ... it does a good job.
Good luck... I know it is frustrating!

My 780D also ate needles. I buy Schemtz Universals in bulk. 80/12's. My machine does not like Sulky threads - no issues with Floriani or Metro.

My machine will take Floriani or Isacord but no Sulky of any kind. Since it is less expensive I bought Metro thinking it would work...... and had to give it all away. My machine would not sew at all with it.

Hoping you find your answer...it sounds like something is wrong with the upper thread, not the bobbin thread...hoping that you can set up your machine and sew something out with the technician so they can actually see what is happening and not just look at a sample...for me, I have had problems when the thread has not threaded through the upper tension areas correctly or slips out of the uptake...keep us posted and good luck!

Have you checked out Ann's fix it page???? It is for a ULT 2001 called a Super Galaxie 2100 here in Australia, but most Brother machines are very similar. This page has helped me out many times with my 4000 and previously with my 750D. It's worth a look. Best of luck, Lyn. xx

My 4000 played up heaps until I switched back to the Brother bobbin fill. I think it's the most expensive bobbin fill, but he works like a dream with it. xx

I use Brother bobbin thread--
As I mentioned in my other replies I am at my wit's end.
Thank you for your time and God bless you....

I am so sorry to hear of your ongoing problems with your machine and it would seem,your service engineer. It must be so frustrating, not to mention the ongoing costs involved.

Have you tried contacting Brother USA (link below) for their help. I don't know if your two service engineers are official Brother Service Agents but if they are, I might be tempted to inform Brother of your experiences with them and the costs incurred WITHOUT ANY RESOLUTION. Of course, this action really depends upon your continuing relationship with these service engineers. But as you say, you can't go on like this and need to make your feelings felt a little more strongly. I hope things are resolved for you soon but please keep us informed.

Thanks so much for your ideas.
The Brother certified factory-trained repairperson messed it up more than before--could not figure out which bobbin case to use----or which needle throat plate was the right one. It's a nightmare---I'm glad I have two other Brother 4x4 emb machines I can use--
I will attempt to contact Brother----
And I will take it back to the 35-year repairman and AGAIN show him my samples.
Thank you so much and God bless you....

If you are using bobbin thread (not matching thread) then the 780 should take the bobbin case with the purple dot (not the one with the green screw). Bobbin cases are notorious for creating issues - but if it has been replaced three times it seems odd that you still have a bobbin case issue.

I have 3 DIFFERENT bobbin cases that "REPAIR" people have given me----2 have purple dots on them BUTTTT----1 has a FULL MUSTACHE (the little hairs at the top) with a purple dot and the other has 1/2 MUSTACHE (the little hairs at the top)--------so which one is "RIGHT"----I have tried the genie inserts and they sometimes help but not consistently...Thanks and God bless you.
