My Janome suffered from needle strike to the bobbin case, my own fault. I thought it would sew denim hems like my vintage Elna did. Nope. Just have to pick the machine to use for each sewing job now. I find any slight jam up is invariably due to me not holding the threads at the start, then thread jumps out of take up lever and things go south. So I rethread everything at a jam.

I have found that machines with drop in bobbins are much more “ fussy” than machines with front loaded ones.
Way cool video on how a stitch is formed, I never exactly understood how the knot was made before, thanks!
