problems with machine embroidery Upper thread breaking and nesting below
allycovey   Intermediate AR USA Member since 11/16/07 Posts: 1429	Login to reply to this post Like this post Date: 12/20/12 11:52 AM I was sewing away on my PE 780D and everything was great my designs were coming out just beautiful. THen the needle got hung up and wouldn't move. I took it to the dealer immediately, they kept it for a week and told me there were lots of threads caught in the upper tensions keeping the needle from moving. It was way up in the machine, the tech said he had to take it apart to get it cleaned out. Said the machine should now run like it has never worked before. I am then all excited, until I get it home. I still had the project I was working on when the machine broke hooped up. I threw away the needle I had in the machine (it was a year old) and I threaded the machine and anxiously pushed the start button. After about three stitches the thread broke. I rethread and tried again. Three stitches broken thread. I thought maybe the maderia titanium needle I had just bought was not liked by my machine. So I tried a jeans needle with a big eye. Still thread broke, I got it to limp along until the design was done, lots of thread breakage and backing up, changed the bobbin twice. Pulled out the bobbin and the bobbin case to make sure it was good. rewound the bobbin switched out several needles. Changed the upper tension twice. I noticed it was aslo nesting on the bottom. Tried about 10 different colors. All the same brand thread I have been using perfectly for all this year with no problems. I am looking for suggestions of what I did wrong. my dealer said bring it back, but their hours are the same as mine at work. I have already taken off early twice in a week for this machine.

I know titanium needles last longer than a regular but that's a long time to have a needle in use. I am sure you have something going on here and if you have paid for a fix you better get it back there pronto before they want to charge you again for fixing the problem. Don't ask how I know this. Lol! Maybe someone else can drop it off for you with a long note attached and you can call and check on it to keep from losing more work time. It's a pain when the embroidery machine is goofed up and I sympathize. I have to drive an hour each way to take mine in and leave it for a long spell. When embroidery machines are working well they are great when not they are useless.

You could change the needles every few projects and should be using needles for embroidery. Also make sure your thread isn't getting held up by catching on the spool edge. Also are you using the proper bobbin thread? When you take it back to dealer have them use your thread and your needles and try to re-create the problem. ------ quiltingwolf.blogspot.com

Date: 12/20/12 1:13 PM Yes I am using Brother bobbin thread that came with the machine. I know I used that needle too long but I took out the old needle before I took it to be repaired, I am now using new needles and having all these problems.

Messy stitching on the bottom usually indicates the top thread is not feeding through the tension. Re-thread with the presser foot up and use an embroidery machine needle.

I wonder if I am not putting my needle in properly. Since I got the machine I have been using the needle that came with it. I bought the titanium embroidery needles when I picked up the machine. Do I insert the needle with the presser foot up or down, and does that make a difference? I change needles on my serger and sewing machines all the time without ever having problems.

Date: 12/20/12 3:57 PM My reference to having the presser foot up applies only to the upper thread tension. Foot up opens the tension so the the thread can "seat" into the tension wheels/disks. If the needle was in wrong the upper and lower threads would not "knit" together. But is is worth looking at. Rule of thumb: Flat side of the needle shaft faces away from the bobbin area (top loading/drop-in or front loading bobbin = to the back of the machine and end loading bobbin = toward the tower/hand wheel). Loosen the needle clamp screw and make sure the needle goes in as far as you can push it without effort. Then tighten the screw. No brand of home sewing machine or embroidery needle should be too long for your machine. Singer needles are a tiny bit shorter, but I didn't get from your overview that this was a brand you were using. Take the thread off the spool pin and set it on the table (in a heavy coffee mug) making sure the machine is threading correctly and then begin the embroidery process. If the thread is mis-wound on the spool or the thread is catching on the end of the spool it will pop out of the mug. Occassionaly you can get a spool of thread, no matter what brand that is wound onto the spool incorrectly (bad day at the factory?) If the thread is feeding from the spool without any hang-ups, then the problem may still be with the thread path within the machine. If your machine self threads the needle, the problem can be the internal thread path. I hope a bit of this and a bit of that will resolve your problems. I know how it can make you want to toss the machine into the garbage! -- Edited on 12/20/12 4:07 PM --

You might have a nick or hole on it. ------ Singer 66-16.
