Thanks David.
By "switching" I meant switching from older firmware to 1.19. I wish it was simpler.

Could you make some ALL-IN-ONE firmware file to update everything at once?

I think the switching method is a bit cumbersome. Besides, I suspect that running the web-server in ESP is better for stable printing, there won't be any lags when the web-interface is updated. I vaguely remember that the printer used to freeze for a moment when I connected to duet 0.8.5.

I'm not sure I want to upgrade to 1.19. The web-server works OK for me.

Can I just upgrade DWC to 1.16?

Please make it possible to choose and move/delete multiple files.
Thanks

Thanks!
I had 117 files in "gcodes".
It probably stopped showing new files after 95.

Please make some interface to choose and move/delete multiple files.

I counted some 95 files in web-interface.
Is there a way to remove them fast?

Yes, there are many files, I can count them tomorrow.

BTW, a few times I wanted to clean the files, but could not find a way to choose and delete many files at once. Is there any trick to do that?

I use Chrome

Hello,
I upl;oad and print a file but it doesn't get to the G-code files list. I think this problem appeared after updating to 1.18

Firmware Name: RepRapFirmware for Duet WiFi
Firmware Electronics: Duet WiFi 1.0
Firmware Version: 1.18.1 (2017-04-09)
WiFi Server Version: 1.03 (ch fork)
Web Interface Version: 1.15a

I think you can adjust autotuning to more agressive temperature rise, even if it leads to a small overshoot.
