Hi, i run a photobooth business and the M50 Mk1 has been serving me well for the past 3 months.
My connections are M50 to usb to Surface pro 6 and for power it'll be CPS ac adaptor and flash will be those generic 1 pin hotshoe with sync cord to my external strobe (300di).
Recently my flash just don't fires at times like maybe every 5 shots, there will be 1 that the flash didn't fire.
Also, when the booth is stationed with no activity the flash also went on a rampage randomly fires.
My slave switch is off.
So due to this incident I change 3 different strobe all behaves the same.
I also change the hotshoe and sync cord (new) it's the same too.
In the end I even change to an older 700D and it's the same either!!!! What happen!!
