I know about the "low bobbin" warning. Mine has it, but as of yet I have not reached that point before pulling it. I want to know before I start a design if the bobbin is going to get there, not be warned that it is low before it's too late.
I'm not a sewing machine tech, nor have I spoken with one, but I know the "techs" have a diagnostic procedure for displaying total stitch count. I wish that info were readily accessible to the owner/operator. Maybe they don't want us tampering with the odometer? LOL
