@fcwilt @Phaedrux @wschadow You can find my updated v3.4.1+1 firmware builds for standalone mode here: https://pkg.duet3d.com/RRF-3.4.1plus1.zip Please let me know if they fix the FTP transfer problems. The issue where uploading config.g resulted in an empty file may be fixed by these builds, too.
I'm out of town for a few days.
I will test this new firmware as soon as I return home.
Thanks much.

I just tried the following using FileZilla set to single connection and transfer limited to 500kb/s
On past usage all of these tests gave multiple zero kb files both directions- Bulk upload of all my filaments (25 directories each with 3 files) - OK
- Bulk download of same - OK
- Bulk download of complete system (700 files in 25 directories) - Only one failed transfer.
File was 0/www/css/OnScreenKeyboar
It was not 0kb, it failed to transfer. Re-queuing worked.
FileZilla didn't give a clear reason why the transfer of that file failed, but as it was reported I would call the test successful.

@owend Was that with @chrishamm's updated firmware?

Yes, it was.

I finally returned home and tested the new FTP code.
On all of my printers (two Duet 2 WiFi, one 6HC and one Mini 5):
- I was able to download all of the files from the SYS folder via my FTP client
- I was able to upload all of the files to the SYS folder via my FTP client
No sign of file loss or truncation.
I will now continue with my normal activities using FTP and see if I encounter any problems.

I have returned to using my favorite editor in, for lack of a official term, FTP mode, where files are automatically download/uploaded as they are opened for editing and then saved when editing is done.
So far it seems to be working fine - though I have been keeping my fingers crossed.
JOOC what was it that you found and seem to have fixed?

@fcwilt Thanks for confirming. All the network responders in RRF could ignore incoming data when a transfer had finished before incoming data was actually processed. So sometimes files could be truncated or when transfers timed out, the opened file would remain empty. It may also fix the issue some users had where config.g could be empty after uploading.

Thanks for the feedback.
I will alert you if I have any problems.

I just finished editing everyone of the 60 files on one of my printers (Duet 2 WiFi), using my editor in "FTP" mode.
FTP Mode Summary
- when the editor opens the project the file names, in a specified folder, are downloaded from the printer and displayed as a list
- when a filename in the list is clicked the editor downloads the file from the printer and opens it in the editing window
- when the edited file is saved the editor uploads the file back to the printer
I made non-trivial changes to each of the 60 files over three days.
So far no sign of corruption or truncation.
I will repeat the test on another printer which is using a Duet 3 Mini.

I just finished the same set of non-trivial changes to all of the 60 some files on a printer using a Duet 5 Mini.
All seems fine.

Thanks for verifying. Good to know this bug is finally squashed.
