There's an update on the Bernina site that you need to download that corrects that issue. It's under Support/Downloads, and the firmware version is 29.39.00

I have an 830 and I found that before I selected anything or attempted anything that required a C or D foot, I had to put the presser foot on for the machine to "read" and then do my selections. I find that if I've pushed too many soft buttons, I must do a "restart" which is turn the machine off for 10 seconds and then turn it back on with the proper foot already on.

Personally, I find that I must treat the 830 more like a computer than a sewing machine. I used to sew to get relief from my job which required me to problem solve computer/software problems all day long. As I progressed from the original 830 to the 170 to the 630 and now the 830, I find I have to put my techie hat back on. Good thing I'm retired now!

Did you tell the machine which foot you have attached? I got that message yesterday after I changed to that foot and I hadn't done that. After I chose 37D in the presser foot selection I did not get that message anymore. Hope that helps.

No - I have the regular throat plate on. Any other foot doesn't give me that message. I know this foot was working on the machine because it was on the machine when used by Libby Lehman at Art Quilt Tahoe (which was where I bought the machine "used" at the end of the class).

Do you have a straight stitch throat plate on the machine which would not allow zig-zag or other side-to-side stitches?

On my Pfaff, this is what that means -- switch to a zig-zag throat plate.

I just got home with my 820 (adore it). When I attach the 37D patchwork foot, I get the icon on the screen that shows the needle crashing into the presser foot. The entire area above that which shows the needle position turns pink. I have the needle in the center position. Any ideas? Thanks in advance!
