Is my set up wrong ?

edited October 2016 in V6 II Problems
Hi everyone,

I freshly purchased a RF60 and pair of V6 II ( both with the latest firmware ) to use for D500 and X pro2.
After having spent hours and hours, my set up is still too unstable to use on professional purpose and I hope someone could help me out.

In both case It only works one time out of, say, five or six. 
All the units are always set on the same channel and group. I used the eneloop batteries fully charged.
Flash is set slave mode. I also tried on the receiver.

With D500, flash fires but does not synchronize above 1/250. Even though flash fires, above 1/250, I only have the flash effect at the bottom of image, not the whole image so HSS does not work.
Trigger set up: camera system Nikon, Flash system Auto and I tried Nikon as well, Sync mode both Normal HSS and Power sync.

With X pro2, I have had my trigger learn HSS and turned forced HSS On, took the hot shoe spring off. When it works, I  noticed that at certain distance, either flash does fire but does not synchronize ( image taken with no effect of flash ) or does not fire at all although the trigger and the receiver talk each other when I use the test button on the trigger.

Thank you in advance

    Jst to confirm, what are the firmware versions currently running on your V6 II and RF60?

    To help us better help you, always state the exact firmware version installed on your Cactus device(s), such as: "1.1.013", "FUJ.1.002", "v.103".

    For the time being, Cactus V6 (MK1) running on firmware version 2.1.001 can be triggered by a V6 II (MK2) running on Multi-brand HSS firmware (e.g. 1.1.013) and not by X-TTL firmware versions: PEN.A.001 and OLY.A.001.  No schedule has been released yet. 

    Cactus RF60X / RF60 Firmware versions A01 and A02 currently ONLY works with PEN.A.001 and OLY.A.001.  Other "A" version of X-TTL firmware will be released soon. For both Multi-brand HSS and X-TTL firmware versions (FUJ, SIG, SON), install firmware version 103 / 205 on your RF60X / RF60.

    Cactus RF60 is now an off-camera TTL flash with firmware version 205 or later!

    Metz M400 (for Fujifilm) is now supported on the Cactus V6 II (HSS and TTL).

  • It reads as if you have a V6II receiver attached to the RF60? You said you had the flash plus 2 V6IIs ..... It is not necessary to use a receiver on the RF60 as the flash has it built in.....

    Sorry if this is not the case, but just wondering if this might be an issue .... ?
