SimpleBGC v.2.56b7, Canon 5D3+Canon 24/1.4 L II
I noticed that if I turn off Beholder DS1 and keep it for minute or more with USB cable connected to my notebook, after turn Beholder on, ROLL axis changes the horizon. Also ROLL axis does not keep the horizon angular during Beholder’s handle movements.
If I press “Write” button in SimpleBGC, even without any changes, ROLL axis works OK and keeps horizon.
If I turn off Beholder DS1 and keep it for minute or more without USB cable connected, nothing wrong with ROLL axis.
