Godox X1Tn/Flashpoint R2 Transmitter stacked on top
I've been trying unsuccessfully to make v6II trigger my Godox v850ii/Flashpoint R2N flashes via a
stacked X1Tn on top of v6ii. All units are are with latest firmwares.
The v6ii recognizes my camera (Pentax K-1) and when the v850ii is on top of the v6ii both camera and flash system are recognized fine.
When the X1Tn is on top however, the flash system is recognized, but not always. Moreover, if I manually trigger the X1Tn device, v6ii "forgets" the flash system.
If I manually trigger the v6ii (while it still recognizes the X1Tn unit), I get a short LED indication on the X1Tn, but (it almost feels) not long enough to trigger the wireless system and my flashes.
I initially bought the Flashpoint rebrand, but because the screen is defective, I will be returning it. In the meantime (suspecting that the defect could be deeper), I purchased a Godox X1Tn. Functionally, both units were identical and both units do not play ball with Cactus v6ii.
Can anybody help?
P.S. I was able to achieve HSS by stacking a Flashpoint R2 Zoom for Nikon which was serving a wireless master to Godox v850ii flashes. I would rather use the X1Tn trigger as lugging the flash on top of the Cactus on top of the camera for a real shoot is very inconvenient.
P.P.S. I suspect I can also use a second v6ii unit to trigger the V850n flash, which in turn will trigger the rest of the flashes. I suspect this is the only workable solution at this moment.
