The first M20 done on connection is missing the L flag. #4493
Closed
Description
The problem
With the latest version of Marlin with Cap:EXTENDED_M20:1 the first display of the file list after connection does not show long filenames but refreshing the list does. The first M20 command that is sent immediately after the M115 does not have the L parameter but subsequent ones do.
It looks like the M20 command is built and added to the send queue before the results from the M115 have been parsed and the EXTENDED_M20 capability set.
Did the issue persist even in safe mode?
Yes, it did persist
If you could not test in safe mode, please state why

---------------------------------------------------------------------------
Your printer's firmware supports host action commands, but they are
disabled. The firmware will not inform OctoPrint about job pause &
cancellations, filament runouts, and similar firmware-side events. If you
want this functionality, you need to change your firmware's configuration.
