Hi, Arne,

Could you attach your jeol.cfg so that I know your mag range and lens series ? We should do a few tests from where you connect to jeolcom with direct python script. I will prepare one.

Arne,

From the jeol.cfg you sent, I found a few parsing errors and it also missing for each lens series since you are using PLA

IMAGESHIFT_CAL_MAG%LS4 = 50000

Could you try some test with the config from where you use JEOL external access within python IDLE
so that exception can be shown ?

form pyscope import jeolcom

# Initialize the class
j = jeolcom.Jeol()

# This should set sequentially all magnifications
j.findMagnifications()

# This should git back image shift
j.getImageShift()

Dear Anchi,
thanks for the answer -
I have copied the modified Jeol.cfg into pyscope and performed the test you suggested.
When I run findMagnifcations the scope cycles through all available mags and also the imageShift runs without error.

As suggested I then ran start.py directly on the Jeol Computer - without selecting the camera.
Logically I could not create a preset (camera missing) but still the get magnifications button is greyed out unfortunately.

Is there maybe a writing permission problem?

your help is much appreciated

thanks
Arne

Don't worry about creating preset, yet.

read write at this point of the program is only to database. If you can create session, return to session, there should not be I/O to database issue.

Does "Jeol" show up in Instrument ? Could you show me a screenshot ? Maybe I will spot something. Did you get the same error in the terminal ?

Dear Anchi,

I can create and return to the session
I can load and get connection to scope and camera PC (on neither side (client and main) no errors)
I do not get any printed error the only thing I get (after pulling or sending a defocus (for example)) is a red cross in Leginon viewer (presets manager) that states: Get value failed focus function not implemented

I get no errors in the terminal window
there it is:
parsing jeol.cfg

(I do not get parsing dmsem.cfg)

does that help?

I did not make the code to write parsing dmsem.cfg

Could you try in the script what I gave you earlier and add

j.getFocus()

If still not work, we should do Skype

Make sure that you do

j.findMagnifications()

This is working very well - I do get the focus
