7 years ago FCCD back to work by start another count_dark(10) measurement, but not when doing RE(ct()). Any comments?

^CA 'deferred pause' has been requested. The RunEngine will pause at the next checkpoint. To pause immediately, hit Ctrl+C again in the next 10 seconds.
Deferred pause acknowledged. Continuing to checkpoint.

Your RunEngine is entering a paused state. These are your options for changing
the state of the RunEngine:
RE.resume() Resume the plan.
RE.abort() Perform cleanup, then kill plan. Mark exit_stats='aborted'.
RE.stop() Perform cleanup, then kill plan. Mark exit_status='success'.
RE.halt() Emergency Stop: Do not perform cleanup --- just stop.

No response after starting dscan(theta). Last scan was good. It seems that FCCD cannot be triggered, see second message below. Also, on the FCCD image, writing data shows always, even when restart FCCD.
