The thread cutting mechanism is dull and needs to be replaced or sharpened. I had the same problem on my machine. I found another post where another user said it has to be replaced every 150 hours of machine use, the cost was 62 dollars. My dealer would not sell me the parts he said I had to bring it in, so I decided to sharpen it myself. See picture for more details. To start take the two screws of the top of the chrome plate to reveal cutter that is above bobbin. The cutter is in two parts both chrome plated. The hook part is held in place by a copper plated screw, the blade (shown in picture hanging off to the side) is held in place by one small screw. I sharpened the blade on a fine grit Japanese water stone (brown block shown in picture) to a razor edge and about a 7 degree angle; the tip of the blade must ride on the hook. This still did not make the cutter work perfectly so I had to take the hook out and reform the small hole in the hook that the blade rides over with a the un-fluted end of a 5/64 high speed steel drill bit. Was not hard to do because the hook is not hardened steel, at least on mine. When putting the blade back on make sure it is resting against the rolled black pressed pin before tightening down.

It is completely normal for a Bernina 180 and other Bernina models to stitch just a few stitches and stop after first pushing the reversing button. The reason for this is so you can cut off the extra piece of top thread so it does not get caught up in the embroidery design. After you cut off that extra piece of thread, press the reversing button (hold it in till the machine starts) then it will continue with the design. Assuming you do not have a problem (a message would come up on the screen) or you are out of bobbin thread, the machine will continue to embroider till either the design is finished or it stops because you need to change the upper thread to the next color. Each time you start to embroider it will stitch about 3 or so stitched and stop. Cut off the extra thread and press the reversing button again to continue.
If this is not the problem you are having then you need to describe your problem better, in more detail.
This should help! Bill
I have found that this error most commonly is a result of a lot of thread caught in the cutting blades preventing the cutting blade from moving. See the "Cleaning around the Needle Plate" in the User Guide or "Cleaning of Knives and Rotary Hook" on page 316 (or 6-6) in the Service Manual located at http://www.brodyrmaskiner.se/service/pr620/pr-620-service.pdf.

It's okay - it's supposed to do that! The Needle Down button has a different function when you are in Embroidery mode i.e. you have the emb. unit attached. It moves the emb. arm forward for two reasons: so you can cut top-side jump stitches more easily between colour changes (you touch the button again and the emb. arm returns to under the needle so you can finish the design); and secondly so you can "park" the embroidery unit when you are finished. You can then turn the machine off, remove the emb. unit and replace it in the carry case. If you DON'T do this, the emb. arm is not in the right position to fit into the moulded carry case properly.
The Broken Thread message usually means that it has started the colour, but the thread has been pulled down underneath instead of making nice locked stitches. Hold onto the thread end until the machine has stopped and beeped for you to cut the thread. This usually solves that problem. Sometimes the thread gets pulled out of your hand so just back up the stitches a few and start over, holding the thread more tightly. Don't tug on the thread - just keep a firm grip.
Designer 1s often cut the bobbin thread too short so that it can't make those nice locked stitches when it starts. You need to take off the hoop, open up the bobbin cover and use your stylus, the tip of a pair of scissors, tweezers (whatever is to hand) to pull the bobbin thread out a little. Instead of cutting it on the bobbin thread cutter, just let it hang outside by 1/8" or so. That way you can be sure there is enough bobbin thread available for the stitch to lock. Don't use the scissors button on the machine after every colour change. Sure, it makes for a tidier back of the embroidery with less work for you afterwards, but if it means you are taking the hoop and bobbin cover off after every colour change then it is not worth it in time-saving. If your machine is doing this - cutting the bobbin thread too short - mention it to your tech. when you machine goes in for its next service. He may be able to tweak the bobbin cutter so it does not cut so close.
Not if you just want to get the patterns off the internet, etc., you cannot, or at least with my older version, make your own designs. You need to download the program to your computer. Its pretty simple if you get on the internet and download the designs put your palette on your computer, go to the designs, with a blank card, and load the patterns. Hope this makes sense.
