K30 and Yongnuo 560 iii

I'm having some difficulties and I'm assuming I'm making a dumb mistake. With the flash mounted on the hot shoe and the camera in automatic, the flash fires every time. When I turn to manual, the flash will not fire. What am I missing?

So I'm not sure what's going on, but I don't think its the flash, which would be my first guess, given it's a Yongnuo. It has been firing consistently in all modes but manual. Then out of the blue it starts firing in M. Problem with the camera or hot shoe?

You may have the flash on RX, S1 or S2 Triggering mode (3rd top button from the left - just cycle through till it works)

So now I know it was something stupid I was doing, and I know what, but I don't know why. At a shutter speed of 160 or less it fires, over that it does not. So 160 is the max for flash?

And paging through the manual, I answer all my own questions. Thanks folks!

1/180 is the max (to get 1/180 instead of 1/160, you have to set the camera to 1/2 EV steps instead of 1/3 - it's in the first custom menu). It's a limitation of the shutter design - if you tried to use a flash and go faster than 1/180, you would get black bands on the image. Pentax' solution is to just disable the hotshoe at speeds over 1/180.
