Problems with HSS and V611

edited November 2016 in V6 II Problems
I am having problems with getting consistent connectivity between the V611 and the hotshoes on my Fuji X-T1 and X-T2s despite removing the hotshoe springs. Sometimes the 'F' shoes up in the camera icon and sometimes not. When the unit is in the hotshoe there is some play even when it is tightened with the lock lever. When I do have connectivity, I'm having problems with the Forced HSS either not triggering the flash on the RF60 or triggering but with several seconds delay. I have updated all the firmware recently. Any suggestions?


    1. Try re-doing the LEARN HSS process in case it actually failed in recording the timing on the first run.
    2. Before shooting above camera's x-sync speed (1/250s on the X-T2), manually switch ON Forced HSS by pushing the Adjustment Dial.
    3. Similarily, before shooting at or below camera's x-sync speed (1/250s on the X-T2), manually switch OFF Forced HSS by again pushing the Adjustment Dial.
    4. Make sure both the V6 II are running on the latest firmware version (1.1.005), and on the RF60 as well (v2.04).
    5. Try doing a Factory Reset.

    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).
