Inconsistent power with Canon speedlite 600EX-RT
I recently purchased the Cactus v6 II for my Canon 5D Mark III along with 4x Canon 600EX-RT speedlights.
Cactus v6 II is updated with the latest firmware (may-2017),
Camera and speedlights are recognized very well by the Cactus triggers and everything works fine.
The problem is that while shooting the speedlights intermittently fire at full power.
It happens on 3x 5D MKIII bodies and 6 diferent 600EX-RTspeedlights.
I have no clue why this is happening and how to fix it.
1. Camera on
2. Speedlight on (ETTL)
3. Cactus V6 II on
Hopefully someone can help me out with this issue.
Thanks in advance.
