Why doesn't it recognize that an embroidery hoop is attached?

I assume you mean a Bernina 830. If you have removed the slide-on table, I have two possible solutions. I've seen this with a couple of Viking embroidery attachment units. (I am also assuming it's not a hoop issue.)

You could have corrosion on the pins that send the signals between the embroidery attachment and the sewing machine. Remove the embroidery attachment and turn off the sewing machine. Unplug the sewing machine. Spray the pins with an electronic contact cleaner; one example is here: http://www.homedepot.com/p/CRC-QD-11-oz-Contact-Cleaner-02130-6/202262505 . Push the embroidery attachment into the sewing machine by lifting up the far side and then sliding it into the port. Remove the embroidery attachment. Repeat this a few times. (The friction of the insertion and removal will remove any dirt or corrosion.) Plug in the sewing machine and turn it on. Try connecting the embroidery attachment. If it works, remember to clean the contacts the next time the embroidery attachment isn't recognized.

Once I helped someone with two sewing/embroidery machines with an unrecognized embroidery attachment. In that case, the person swapped which embroidery unit went with which machine. The contacts were not the same and didn't mate. Once the correct machine and embroidery unit were paired, the embroidery unit was recognized instantly.

I hope this helps. If it doesn't, you may need to talk to your Bernina repair technician at your local shop.

Perhaps the machine is not recognizing the hoop you have installed. Could be a computer component or software glitch or something wrong with the hoop itself.

You might try contacting a local machine dealer for support or contact the online manufacturer support.

You have probably got the machine set to use a different size hoop. Click on the hoop icon and change it to the size you are using. Hope this helps you.

Calibrate the embroidery hoop


Note
The embroidery hoop can only be calibrated with the oval hoop.. You'll find the instructions for each machine in the relevant user manual.

Your machine would be able to perform 5 X 8 embroideries. The hoop size on this machine is recognized by the machine itself, depending of the embroidery file size. So it the embroidery is small, it will indicate that the small hoop is needed.

But U can use the large hoop, position the embroidery where U want then perform another embroidery on the sams hoop.

TRICK : the embroidery size exceeds the hoop? reduce it in X and or Y using this function on the machine

Depending on your model of machine this problem is solved by replacing the hoop attachment unit on the hooping arm. (hoop sensor cable is not properly welded)

First turn off and disconnect embroidery unit and hoop from the machine. Plug machine back in and connect the embroidery unit only and turn the machine on. Reattach the hoop and test to make sure it's secure. Your hoop might not have been attached snuggly enough or you might need to put on the small hoop.

My machine did the same thing. I had several frustrated nights ans then it just started to work. Some suggestions that I had was that there may be dust where the units connect. Not sure what I did, but it worked.

Joan, there are 3 micrositches on your embroidery unit arm. these switches are depressed when you attach the hoops, it appears from your comments that one switch is not functioning. This could be simple, it is out of alignment or more complex it is broken. Either way you need to take it to a professional for repair.

The embroidery unit needs to be calibrated. Can only been done by a trained dealer. you can relax, it is not a major issue and shuold not cost you a arm and a leg. Ask the dealer to also calibrate your touch screen and download the working hours on your machine.
