bobbin shaft shifted/machine jammed: I asked the repairman why this happened, he said he didnt know, might have been thread tangle pull it out of position?

The timing was knocked off due to a jam. This can be due to mis-threading of the top thread (presser foot up), thread caught up on the spool or spool pin or the bobbin may have been inserted so the thread was feeding in the wrong direction or jumped out of the guides. When embroidering a large item, make sure the outer area of the fabric (the amount not hooped) does not fall into the path of the needle - this will really knock the timing out of whack. Stay with the machine as it stitches so you can cut quickly the power should problem come up.

The company web sit may have that info. Meantime, flatten it in vise and maybe use a washer over it. A local machine shop would make a better one for a couple bucks

It happened with me also, I started watching for the pin to start drifting out of place and any time that I noticed it starting to happen I used a pliers to push it back into place. I suppose that if it gets worse you could use a drop of super glue to secure It in place.

Either you are not threading your machine correctly , your bobbin is not threaded correctly or you may need to adjust the tension on the machine. Don't adjust it a lot at one time. Just a little at a time. You may need to play around with it. Have patience.

Thank you so much for your reply. I finally ended taking the machine in for repair. Apparently a part needs to be replaced.But I will keep in mind the MX850 in the future.

Check the belt first. It might be broken or just dried out and slipping on the pulley. Next, check to make sure your cable is ok. You might need to adjust it to get the belt to engage.

I think at the bottom side of the machine and at the top where the thread go's or if not well, call the company and they can tell you more. and sorry if I cloud't help you.

Check to make sure it's not screwed down too tightly. A little bit of lubricant in the part that spins might help also. The handle really does move it quite nicely. You may want to check to make sure nothing like packing material or debris is stuck in it, effectively jamming it tight.

Had no issue with mine either.. Thread was fine, No play whatsoever with the fit..

im not sure Neil, I didn't have this issue, did you strip the bolt that the nut attaches to? you may just have to slowly stop turning the nut when you feel the tension. I apologize for not a better answer.

...whoever you bought it from...may not respond favorably. Why not try jiggling the connector from the motor to the board? It's what I did when I got the same prob. Loose connection...

I did have the tension adjuster go bad on me too, and I purchased a new assembly because the threads were gone. The new assembly has a slightly better design and has far outlasted the first one.

Put a few drops of medium strength (blue) thread lock on the thread before you tighten it if you are worried about it vibrating loose over time...

its the wrong one, send it back and get the right one. the female part of the shaft is wrong also( look under the plastic piece)

No, I had no problem with the foot press or the bobbin. Try redoing the bobbin it may be in wrong since that happens at times.

Tighten your upper tension. Also, make sure you hold your bobbin with your finger when you are threading it. You should feel a kind of catch then it is in the right place. Lastly, made sure your needle is in correctly and tight, sometimes the vibration of the machine will loosen the needle.
