Question about Bernina Virtuosa 160

3 Answers

Bernina Virtuoso 160 Whilst sewing a buttonhole, the second bead stitches for about 20 stitches and then fails to continue feeding backwards. Hence clumping of stitches in one place and a failed buttonhole.

    Hello,

    Thank you for your reply.

    I think maybe I got someone elses solution.

    You sent me a solution to resolve a thread track problem. My problem seems to be with automatic buttonholer.

    Thank you for your advice.

    Are you using a 3A foot - if so, it sounds like the automatic calibration may have gone out. But before that, ensure that the buttonhole sensor is clean ... put your machine carefully on its back so you can see the bottom of the head mechanism (where the needle and foot are fixed. Look carefully to the right of the needle bar and you will see a small round lens and a similar, but flat lens next to it - these comprise the sensor and work with the two lenses on the top of your 3A foot. Use a cotton bud to gently clean the optical parts of the sensor, being very careful not to push it hard - on some models, you can inadvertently push the sensor up into the head, then it wont work at all! Once you've cleaned it, re-check whether its working. If it's still not working, it will have to be re-calibrated - unfortunately, on your machine, this requires a filter to be fitted between the sensor and the foot, so it will need to go to a proper service agent. I am based in Devon !!!

Make sure you use the buttonhole foot or one with clearance underneath to allow stitching to pass freely under the foot.

feed dogs may need to be raised.

    It sounds to me as if your machine has a sensor problem. You will need
    to take your machine to an authorized dealer/repairmen- they are
    the only ones who will look at your machine.

    Take the back of the machine off and heat the inside of the machine with a hair dryer.

    Take the back of your machine off and hold a hair dryer to it until the button frees up.

Bernina 350 buttonhole - when I hit the reverse button, the machine just keeps stitching backwards. It doesn't stop to do the tck and then go forward again.


Here's a video:

It looks like the Reverse button just needs to be "tapped." On my machine, if I hold the Reverse button too long, it turns into a continuous reverse until I deactivate it.

Bernina 350 16 Buttonholes

If it still won't make buttonholes, you should take it for service. On machines that have the "eye" on the presser foot, the machine needs to be calibrated to use the buttonhole presser foot. Be sure to take the presser foot when having the machine serviced.

How do I make a new buttonhole on my 1260? B


Hi Karen,
Sew two parallel lines of overlock stitches very close together. Then see overlock stitches accros the ends of the first lot of stitches to close them off. Finally, carefully cut the fabric between the first set of stitches. Try this out several times on some scrap fabric. You'll need to get the spacings sorted out.

How do I make buttonholes on the Bernina 180?


I don't know about your Bernina but mine you have to manually set the button hole size every time you do a new button hole size. Practice on a scrap bit of fabric. I think you push the buttonhole button - sew which I think does an end, push the button again, sew for the distance forward you need and push the button again, and sew the other end and push the button again and it should go back to the beginning. That's off the top of my head, I could be wrong but try it on scrap. I think it might then have set the size until you change stitch types and it should continue to do the same amount of forward and back stitches with each button press to tell it to go forward, end, back, end etc. But practice! My machine has trouble feeding the fabric evenly.

My Singer 2950 buttonhol-er stitches only one side of the buttonhole. It does not reverse and finish the buttonhole. What to do??


Have you pulled down the buttonhole trigger lever at the back of the sewing area? most modern machines have one of these - when you use it with the button hole foot, you'll see the foot has a little piece that sticks out and triggers the lever to begin stitching the reverse bead and bar tack of the buttonhole.

My sewing machine was working fine until I changed the stitch length. Now it just stitches in one spot. I didn't change anything else. I've rethreaded the top thread, bottom thread, and changed needles....


So is the stitch length now back on 2.5 for a normal straight stitch?

Or have you perhaps put it into a buttonhole sequence or something where it is sewing in the same spot.

Or have the feed dogs been disengaged accidentally, this would also mean no forward motion during stitching. Can you run it slowly, no thread, no presser foot and see if the feed dogs are going through their normal up and backwards movement to check this?

Have you got the manual to trouble shoot and find how to renegage the feed dogs if this is the cause. Sometimes it is a slide mechanicsm on the free arm or at the back of the main sewing area.

How do I use the button hole foot on the Bernina 807 minimatic?


There isn't an automatic button hole on this machine. You can do it manually. Thread the bobbin thread as usual, but put it through the little hole on the hook in the bobbin case. Set the stitch length between 0 and 1, like a nice satin stich. Set the needle position to the far left and the stitch width to 2. Sew down the left side. Center the needle, set the width to 4 and lower the feed dogs, stitch about 6 stitches across the bottom. Then reverse the direction, set the needle to the right, stitch width to 2 and go back up the right side. Lower the feed dogs again, set a wide stitch and finish the top.

Another good option is to buy a universal presser foot shank from Bernina and then attach an old cam type buttonhole attachment from Singer. They make beautiful buttonholes and you can even do a keyhole button hole.

Bernina 240, won't complete the buttonhole


Double check the instructions and if there is still an issue, call the Bernina dealer and tell them what is wrong.

Ask if someone will be available to look at the machine when you come in .... you need one-on-one assistance.

Automatic buttonholer won't work


Your buttonhole foot needs to be recalibrated to your machine by a technician. Takes about 5 minutes or so.
