machine learning

Over the course of the last year, the zig-zag capabilities of both of my beloved Bernina machines has degraded, to the point that I am currently the possessor of three straight-stitch only machines. I took apart the Bernina 1230 to see if I could recognize anything. I found capacitors and resistors and some mysterious things. Consulting with local experts, we concluded the board was probably done. Making some minor tweaks and reattaching it produced no change in diagnosis, so I ordered a replacement board. That arrived yesterday, and I installed it this morning and tested the stitching capabilities with the back and sides open to the breezes. I shocked myself only once, the zig-zag and decorative stitches seemed to be functioning again, so I closed everything up and now have one machine back close to spec. I did manage to cut myself on something though, so either I have promulgated a blood pact with the machine and it is now my servant forever, or I have let loose a demon within it. I’ll report if anything deeply suspect occurs.
