I recently purchased the Explor 600 with r2 trigger. The flash fires great with my godox xt16 trigger but I can't seem to fire it with the Fuji compatible r2 trigger (which was backordered and just arrived). I've double checked all the channel and group settings. The odd thing is that the r2 trigger fires my ad200 just fine so I'm assuming that I've overlooked a setting somewhere with the r2 trigger to explor 600. I would appreciate any ideas. FYI, I'm only using manual mode. Thanks in advance for your time.
