camera not reliable at moderate speed

[David]

My Nikon Z6 camera when commanded from a script will skip frames and slow down and sometimes not update the exposure per the script if it is commanded at more than a photo every 1.5 sec or so. The camera itself is capable of 10 (or maybe 12 frames per sec - I forgot). I want to speed up the camera to get lots of shots of the diamond ring and Bailey beads. I know the buffer on the Z6 is only about 45 frames or so but that is enough. I would also bracket some exposures if I could shoot faster.

Is there anything I can do to reliably get more shots per sec?
