Question about Bernina Virtuosa 160
When you turn on my machine, the needle makes a funny clicking noise, and starts jumping slightly side to side. Eventually does stop, but sometimes takes a while. Also, it sometimes sew slightly zig-zag when straight stitching, and the stitch length is hard to make longer, it always starts off really small (1 or 2 ), and can get it to lengthen only by winding the stitch length dial to the longest setting (5), then bringing it back down in small increments. Sometimes when sewing the preset medium stitch length zigzag, it will jump to large stitch length zig zag, mid-sew. Do I have a costly computer board replacement on my hands, and/or stepper motor???? I have been told by my local bernina agent, that there isn't really a way to test it, they would just start replacing the boards (it has 4), until the problem comes right - a bit hit and miss, and no guarantee the problem would be fixed, with the possibility of a large bill for trying. I love my machine, but not sure whether to take the risk, or walk away from it and buy a new one - equivalent around $2500. YOUR HELP WOULD BE APPRECIATED! :-)
You will most likely find that just adjusting the stitch length and width controls for a while will correct the problem (if the machine has been sitting idle for some time the stepper motor linkages seem to stiffen up a bit but i have good success with continual adjustment until they free-up.
also try switching machine off and on again to ensure it resets correctly.
the combination of both above fixes works 95% of the time - otherwise, as you mentioned circuit board and or stepper motor replacement may be necessary (however if both length and width are playing up it is unlikely to be an electrical fault).
