Thanks Slashee, but the SD card reader on my printer is broken, so that's not an alternative for me. I hadn't had any significant problems with USB printing until yesterday (after the OS upgrade). It's probably a change to the way hotplug is detected and reported, since I think that was necessary before. Thanks for the heads-up on Octoprint. I've now got that working and printing is back on track :-)

Cura version: 5.7.0 OS: Linux Mint 21.3 Printer: Creality Ender 3 S1 Pro Project file: N/A, the printer isn't detected before creating a project. I've been using the Cura AppImage on Linux Mint 21.2 for a while without any serious issues. I always have to disconnect and reconnect the USB, sometimes more than once, but I can live with that :-) Yesterday, after finishing a successful print, I upgraded my system to Mint 21.3 and now the printer is no longer detected, regardless of how often I reconnect the USB. I haven't looked at the debug before, because it was working OK, so I can't say whether any of the current messages are new or not. I think the following shows the relevant parts of the debug output: Gtk-Message: 17:19:03.767: Failed to load module "xapp-gtk3-module" [MainThread] UM.Application.initialize [163]: Initializing UltiMaker Cura [MainThread] UM.Application.initialize [164]: App Version 5.7.0 [MainThread] UM.Application.initialize [165]: Api Version 8.7.0 [MainThread] UM.Application.initialize [166]: Build type None . . . 2024-05-05 17:21:26,279 - DEBUG - [JobQueueWorker [0]] USBPrinting.AutoDetectBaudJob.run [39]: Checking /dev/ttyACM0 if baud rate 76800 works.

It still connects to my phone, web camera, graphics tablet, etc. It's just an issue with the 3D printer. If there is any more information needed, just let me know and I'll provide anything that's necessary. Thanks.
