Needle won't stay in left position when using zip foot - bernina 1530

pls tight ur button hole foot...while inserting needle

Does it straight stitch with a zig zag foot? Go back into the menu and clear everything then go to straight stitch, then press the little buttons beside the Zig Zag dial to position the needle left or right

Please tell us the make & model machine.

Perhaps this will help:

Bernina 1630 Zipper Foot

Look at the knob which creates the zig-zag stitch (1-4) at the top right of your 930. In the center of that is a silver knob that rotates right and left. That silver switch moves the needle position right and left.

Unless it needs to be oiled, you may need a service call.

I have a Bernina Virtuosa so not the same machine - but this may help. There is an icon on the front of the machine - it is a needlepoint pointing at a dot in an oval - there are arrow buttons on either side. These move the needle left or right of center and it shows on LED screen. I checked mine just now and if you turn machine off and on it resets to center automatically. Hope this helps - Happy Sewing!!
