Cactus V6 II freezing X-Pro2 during "Learn" set up for HSS
I can't get the Cactus V6 mark II to work with my X-Pro2 and 2 Cactus RF60 flash units (both now running firmware 2.02) Works well at 1/250 but can't complete the set up for hss procedure. When I set it to do the "Learn" shot at 1/1000 the X-Pro 2 shutter refuses to fire either locking up the shutter button or just making it not fire the camera even when the shutter is fully depressed. I have to turn the X-Pro 2 off and on again to free it up.
Then the brand new cactus V6 II unit's on-off switch stopped working after 1 hour and I am awaiting a replacement unit now. I had the unit set to Fuji camera, auto flash detect, force hss, and the X-Pro2 set to force flash (also tried commander mode).
What could be the issue? any ideas? Any help appreciated.
