The flash fires if you connect the middle and the rail - the tow contact - by a wire. Doing this (triggering) by another circuit might helps.
That indeed provided a workaround. Don't like the wobbly controller but it works for now. What I've discovered is that almost all of the K cameras of have this problem and that it was eventually solved by one of the firmware updates. I was searching for a K-3 but when I expanded the search I found out the K7 and K5 and 5ii to have this problem initially and then it went away with subsequent firmware updates. The K-3 an K3ii both still have it with the latest firmware updates although I heard that the first K-3 firmware did not have this problem. But I can't downgrade so I can't really test it.
I would love to know what's going on in terms of voltage or whatever is causing the problem. It is quite a baffling problem. But thanks for the work around in the meantime
