K7 speedlight issues.

Longtime reader, first time poster.
New to external flash and having problems getting them to fire.

I have a sigma EF530DGSUPER and it works just fine. TTL and manual fire just fine on the camera.

I just got in a set of cactus V4's and a Lumopro LP120 from midwest.
After setting up the cactuses, either flash fires on the receiver when I press the test button on the transmitter.

However, neither fires when I actually shoot with the camera.
The LP120 also doesn't fire when attached directly to the hotshoe.

It seems like the K7 isn't firing for anything attached to the hotshoe with a single pin. It also didn't work through the x-sync port.

Just wondering if I'm making some noob mistake and missing a menu setting or something. Anyone have any advice?

Thanks in advance,

Make sure you're under the sync speed of 1/180th sec.

Will it not fire at all in this case, or just fire late?

I was thinking about it more last night and realized I should have tried it on my k10. I'll do that tonight and see if it works on the k10

Found another thread where they say it won't trigger at all if it's over 1/180. That's probably what my problem was.
Thanks for your help.
