Designer 1: upper thread shredding while embroidering
HI, I hope someone can help with this problem. I have had my machine about 1.5 years and in Dec started having trouble with it in the embroidery mode. The upper thread is being shredded until it breaks. I had the machine cleaned and serviced in Jan thinking that would help but the problem persists. I've re-threaded using every possible configuration, changed needles, changed types and brands of needles, changed stichplates, bobbin thread, speed... everything I can think of. I am using Sulky thread, it is new and the problem persists with any color I use. I do not have the problem when sewing, only embroidering.
Re: Designer 1: upper thread shredding while embroidering
I too, have the same problem withmy Designer 1. I just bought ISACORD brand polyester embroidery thread to hopefully solve this problem, but I believe it must be a tension problem. I have a "date" with the repair lady on Friday (11/22/08) and if it gets repaired I will re-post what the problem was. Still love the machine WHEN IT SEWS!!

I find that most problems for me have been from poorly wound bobbins or very dense designs. With the dense design, when nearing the end the hoop starts catching/jumping up with the needle, breaking thread. I use software to decrease density one or two increments then embroider. Clean out the bobbin shuttle and the upper thread path. Change needle & make sure your stabilizer is appropriate for the fabric. If too lightweight it tends to shred causing issues.
I'm sorry your Designer 1 is not feeling well.8*( It sounds like to me you need to get your embroidery unit re-calibrated by your local technician. When was the last time you had your machine serviced? Are the designs you are trying to embroider stock designs or your own designs? Have you tried resetting your machine by turning it off and back on again and let the machine calibrate again? (Take the hoop off before you do this and put it back on after you have selected your design) and try it again. Also how old is your machine? They had a recall on Des 1 purchased between 1999-2004 for a power supply problem. The serial # and recall info is on the Viking website at- www.husqvarnaviking.com. Also do you have enough clearance around your machine where the hoop is not hitting anything while it's embroidering that will throw it of big time!

If you are adjusting the upper tension on your machine and yet there is no difference to the sewing, it seems to me that maybe your upper thread is not in the tension disks correctly. Re-thread taking care to make sure the threads bed down into the tension disks. I pull off about 2 foot of thread from the spool and put my right-hand finger on the thread very close to the spool (the idea is to hold it down so it doesn't move) then use my left hand to take the thread through the thread run. Once I get close to the needle, I tug the thread a little and you can hear/feel it go into the tension disk.
Sometimes it looks like the top thread is the problem, but in fact it is the bobbin which is at fault. Re-insert your bobbin again taking care to click it into its tension slot. If you are still getting bad results, try loosening off the bobbin tension. Use a tiny screwdriver to turn the tension screw (the one just on the outside of the tension slot). Turn it no more than 1/5th of a circle at a time (to the right to tighten, to the left to loosen) then put bobbin back in and test. You should not need to adjust it more than two or at most three times. If you do, something is seriously wrong with your machine's tensions and it needs to see the Sewing Machine Doctor.
The threading may be out of the channels. Rethread. Put in a fresh needle. Make sure you are using an embroidery needle and a new one for each new project. You can't use YLI bobbin thread. It stinks. If all this doesn't help, take it in to be checked These work great when there is not thread stuck in the bobbin case and it is threaded properly. If all is well, it will go like gangbusters.
If the upper thread spool is spinning allowing slack to the inlet of the tension assy and the machine gives a broken thread indication shortly afterward, the pre-tension assy needs to be adjusted. If the machine has the original "snap in" tension assy that was in the first generation of Designer 1, have it replaced with the modern "lay in" tension assy. Slack at the spool should never cause a broken thread indication as long at the thread is in the pre-tension assy. Sulky thread will work as well in a Designer 1 as any other embroidery thread as long as it is properly adjusted. One thing that you can look for, when the machine is sewing, watch the thread as it passes out of the left hand side of the tension disks. It should exit the disks at the 9 o'clock position. If it starts to drift up to the 10 or 11 position and then you get a broken thread warning, the pre tension must be increased.
