V6 II hangs EOS M3

I am facing some issues with the EOS M3

1) The V6 II will disappear on camera after a while (flash icon missing)

2) The V6 II hangs the EOS M3 Ext Flash menu when TTL pass thru is enabled (it force shut down the camera)

3) Sometimes I can enable the TTL pass thru, it goes into an error.

Thank you.

  • Hello @slmka
    1. I wonder if it helps if you manually select both the camera system and flash system as Canon?
    2. The V6 II was not designed to function with any camera's External Flash Menu.
    3. Is the flash set to TTL mode? 
    BTW what flash model are you using?

    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.
