Lambda2M timed out after first measurement because `cam1.NumTriggers_RBV` not found #292

Closed qzhang234 closed 2 years ago

qzhang234 commented 2 years ago

@prjemian Lambda2M timed out after the first measurement because it timed out on cam1.NumTriggers_RBV.

My first reaction was to comment out that PV in the detector class definition, but then I realized that the error did not pass through ad_Lambda2M.py at all. Any suggestions?

Does this PV (8idLambda2m:cam1:NumTriggers_RBV) exist?

qzhang234 commented 2 years ago

@prjemian Looks like the PV does not exist. Any suggestions?

No such NumTriggers feature in that camera. So in your Python cam class, set num_triggers = None

prjemian commented 2 years ago

In conversation, we changed the base class for the cam class, from ophyd's Eiger cam to ophyd's Lambda750k cam.

Will push today's code to branch 150-Lambda2M

prjemian commented 2 years ago

In AD_Acquire there is a path kwarg that is used to set the path the detector uses to write image files and also the path that bluesky will write the DM workflow file. Can't do that since the Lambda2M does not have the same filesystems as the bluesky workstation. Execution fails here: https://github.com/aps-8id-dys/ipython-8idiuser/blob/73d28f5ae6dcf3066e8d9bc79ea7d5ac91b7c041/profile_bluesky/startup/instrument/plans/xpcs_acquire.py#L295-L297 with a permissions error. Suggest refactoring with pathlib and consider det.hdf1.read_path_template and det.hdf1.write_path_template. Also, clarify the meaning of the path kwarg (IOC or Bluesky sense).

I think we want path in AD_Acquire to be consistent with Bluesky sense (/home/8ididata/2022-2/****)

We resolved the Lambda2M NumTriggers question in today's meeting, by starting from the ophyd.Lambda750kCam class.
