Firstly, many thanks to the team for all the hard work!

Newly built Fabscan Pi,

Calibration OK

Scan starts, operates for one full revolution of the turntable, then hangs, and server becomes unresponsive.

Only apparently relevant log entries (repeated many times)

<<2020-08-17 13:40:45,368 [555:1577178208] WARNING - fabscan.server.services.api.FSStreamHandler: Error while trying to trigger the scan processor: local variable 'jpeg' referenced before assignment

It is entirely possible that I have missed something in the setup because

a) This is out of my normal field of computing

b) I am pleasantly fuzzy due to opiates following surgery last week

Any assistance would be appreciated
