    Hello @djbe

    Check the following:
    1. Is HSS activated on the 600EX-RT? You should see a H lightning symbol.
    2. If you use auto-detect for the flash, always switch on the flash first, set it to TTL, then switch the V6 II to RX mode.
    3. Has the hot shoe metal spring plate been removed?
    4. Did the V6 II auto-detect the camera as Fujifilm by half-pressing the camera shutter button while switching the V6 II to TX mode?  Make sure to securely mount the V6 II on the camera hot shoe.
    5. Try re-doing the LEARN HSS process in case it actually failed in recording the timing on the first run.
    6. Before shooting above camera's x-sync speed (1/250s on the X-T2), manually switch ON Forced HSS by pushing the Adjustment Dial.
    7. 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.
    8. Make sure both the V6 II are running on the firmware version 1.1.005.
    Thank you and I hope the above helps!

    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", "NIK.A.001", "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) but not by X-TTL firmware versions:  PEN.A.001 NIK.A.001 OLY.A.001.  No schedule has been released yet for an "A" version firmware on the V6 (MK1). 

    Cactus RF60X / RF60 Firmware versions A04 and A03 currently ONLY works with PEN.A.001 NIK.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.
