NOW for the killer, the pinnical of frustration. My 750 is back at the dealers, Tell me what you would do or expect.
I was happily embroiderying Hoop Sisters feathered star with my new embrroidery unit and jumbo hoop. This is a huge project and takes a good amount of planning and sitting with the machine.
I liked the design and thought this would give my 750 a real workout.
It was going great guns and I had completed 14, 8x8 squares
The embroidery was clean, stitches great except for an occasional thread nest which was probably due more to my inexperience then the machine.
I have been working on this on and off for about 6 weeks.
Two days ago the machine was telliing me that I did not have my embroidery module attached (which I did) I turned off the machine and the flag dissappeared and I continued on my merr yway.
Then it happen again and again. Hmmm thought this was not a great sign.
To make already too long story a bit shorter, other things began to happen.
The machine did not stop at thread color changes and just kept on going like a run away train. Again I turned the machine off and let it reset. It did it again shortly after.
Luckily it did not effect the design. I had to sit in the room and really keep ahead of is so the machine would not ruin my squares.
After a while I noticed the stitches had some looping I thought to change the needle (the one in the machine was almost new)
rewind a bobbin, rethread everything cut out the faulty stitches and contiue.

The machine jammed and when I went to remove e the bobbin it would not release from the caseing. I took the whole bobbin area apart and cleaned it throughly, and managed to get the bobbin out of the case. Carefully putting everything back together, I reloaded the bobbin and could tell it was tight.
on and on with this for a least 45 minutes.
I put the bobbin back in after a careful examination.
It jammed after a few stitches. Repeated amd tried again.
I could hearr a sound that was almost like a birds chirp.
It jammed over and over again. The no module light came on a gain. the stitches looked ok and I tried to finish what i had started hours before.
The final jam the bobbin case and every thing came out dislodged.
I put it all back together and tried to see what was causeing the problem,by carefully looking while I turned the hand wheel slowly.
The bobbin case shot out of the machine and landed several feet away from me.
I put it back in and it did it again.
It must be that the timing is off. And the bobbin case is distorted, plus the computer is not right. Now the bobbin doesn't lock in at all. I took it to the dealer and it will be looked at on Tuesday, because he said he is swamped and its a short week.

7 mos. three trips to the dealer and a trip to bernina prior to this.
Now this happens the machine is broken. A lemon or just poorly engenieered I dont know. What do you all think?

So sorry you had to take it back again.

Not sure what I think. It's been sewing perfect for a while. Why not see what the tech says and go from there? Did you take your module back too? It could need repaired as well since it gave that error code.

I hope your tech can get to the bottom of all this and that the fix will be simple. I agree with Diana... See what can be done and what they might recommend. In the meantime

Forget about the crazy machine for the weekend. Treat yourself to some nice fabric. Do a small project on your reliable 635. And get lots of hugs from DH!

This should be an automatic upgrade to a 780E with extra cost on Bernina.

Oh you so don't deserve this! But I agree with Diana. If something is going wrong with embroidery, you really need to get them the module too. The whole bobbin shooting out thing is rather scary! Have you been embroidering much before this project, or mainly just sewing? What would I do? Gosh, I don't know. I'll have to think on it for you. It's late, and my brain is fried.

Is it a full moon? My 730 is going to have to go in too. I was embroidering and got some really weird message and had to turn her off and back on again, then I was able to continue. It had only done a couple of stitches though, so nothing ruined.
And the bobbin winder is winding so slow it's like impossible to wind a bobbin. It starts out fast, then slows to a crawl.
I'm so thankful my machine is only 3 years old and still under warranty for this stuff. I'm going to play some more before I bring it in.

oh boy, so sorry to hear this!
I don't know what I think about it. I am even more disheartened to tell you that I am having some similar issues cropping up with my 780 embroidery....
I had been blaming it on myself thinking I wasn't threading carefully enough. But, the problem seems so sporadic. Either a whole design will give me problems, and then a whole one will not. I am getting top thread nesting on the bottom, also locking up the bobbin and gears. It particularly happens when it resumes stitching after pausing to allow a thread to be trimmed. But seriously- its happening a dozen times a design, once or twice with each color change.
Yesterday during a design it gave me a weird error message that my embroidery arm was out of alignment or something like that....I removed the hoop and put it back on and it was fine.

I am pretty discouraged for both of us, after hearing your woes. Wouldn't it be great if there is a software patch that needs installing....

I'm so sorry to hear this, you and Raye Ann both. It makes me nervous to try out the embroidery on mine...but I suppose I'd better do so.

Don't know what to tell you, other than wait to hear from the tech, but how many times these problems will crop up in future...it is very upsetting.

If it makes a nice straight and zig zag stitch feed dogs up, I would know that it would be impossible I knocked the timing off at all, or it would not be stitching like that either. Also I think anyone can probably untime any machine, by embroidery design (too many tight stitches all piled up on top of each other possibly and if continuing to try to keep on sewing like that if in the extreme), or just sewing, but at the same time, a machine with a cracked hook gear is just really untimed too, as if your gear is not intact, nothing to hold everything in the right place to be in time either. Sometimes if it is just a small crack and no one noticed it, it might be retimed and then go out, real soon later, then it could crack even more or not hold in time, even the second time around.

I think undue vibration, if things jiggle loose or your sewing surface sensitive to vibration, has anything to do with it on occasion or way more often an uneven surface a machine is sitting on sometimes, can make it think it's embroidery unit not plugged into there maybe sometimes.

I think when a machine embroiders something out, a stop code in the embroidery design is telling it when to stop to change colors. They get in there when the person makes the embroidery design. But sometimes they might forget to put one in, or when they make many different file formats of an embroidery design, one file format conversion can have an error and be missing that stop code that some other one might not and they might not always test enough to catch it.

If so, you got to go back and check that in some embroidery digitizing software instead and confirm it's (the stop code) is even in the original embroidery design. Also I think when you feed an embroidery design into an embroidery machine, it's not even taking that exact design, instead it's getting copied into there most times, and then that copy instead sits in machine memory. And machine is actually sewing off of still additional copy of it, instead. So kind of a lot of stuff happening, maybe.

Sometimes if sewing the same embroidery design from machine memory out over and over again, for just hours and hours, something might go corrupt or kapoohy in it, from within machine memory in there and change your copy of the digital file in there. In that case, if you look what you fed it, you might not even be seeing it as the copy that is in there anymore, but if you really can then send that design in actual machine memory back into a computer and check for stop codes or what ever and see them there or not, then that's good, but if you can't, it's pretty hard to know for sure what may have happened.

I think if embroidering along for a long time like hours and hours and if at the same time on the same house circuits, the machine gets hot or you got something that's pulling a whole lot of power, like a 1800 watt automatic shut off/turn it's self on when touched or moved iron, or you plug in a 1800 watt hair dryer or such, that big power fluctuation right then can even do something to an embroidery design data that is now held more in machine memory sometimes, like corrupt it sometimes, and effect it's sew out that way too.

I think most thread jams occur (other than bad digitizing when embroidering) when you suddenly got no or not enough top thread tension for some reason, but that could be any reason, like thread stuck in a machine someplace, or catching on something then getting released, or thread jumping out of a thread tension slit, or just a whole bunch of things. It also does not take much of a bit of errant thread caught someplace to foul something up sometimes either.

If a bobbin case will no longer go into a machine though, and nothing wrong with it, then maybe something wrong with your hook or your gear, so those have moved some things and it can't even fit in there.

I think you got so many issues on that one sew out session though, there probably is no way that they all can be related to each other, and all caused by any one thing. I think you must have been unlucky enough to have several different and maybe not all that related at all, things happening, sort of all at the same time.

So I'm not sure it would always have to be a lemon or badly engineered at all, just depending on maybe why some of those things happened. Maybe you will find out, some of that, when they look at it? I would for sure now, be wanting them to look with real eyeballs at both my hook and my hook gears and everything around them though, unless there was just something chewed up and trashed and wrong with my bobbin case instead.

So no answers, just some kind of random thoughts. It does sound like you had a horrible sewing day though, and maybe time for some chocolate or wine or a hike someplace or at least do something real different and nice for yourself!
