Great, now the hint from spants applies. Under /dev/serial/by-id/ choose the right connection to your printer (should only be one if nothing else is connected) and see if everything works after restart the Octoprint-Docker.

That's a point, but to test whether the printer wants to respond at all, ttyusb is ok. /dev/serial/by-id/ usb_Prusa_Reserve… was also the default in my installation and didn't work. The hint that it is better to use /dev/serial/by-id would have come after the success message.

Hey Notrial, maybe you didn't choose the right printer USB port. It still looks like the original settings Try to choose the ttyusb0 or suitable for you by selecting it. For me, TTYUSB0 is the first printer and TTYUSB1 is the second.

Hi there, I have two Dockers running with Octoprint. My two printers connect and work as well. I have a webcam for each printer, but I can't get both to work. Only the one whose Docker starts first will work. Of course I adjusted the ports (5005, 5006 & 5007) and the video DEV to video2. Docker internally I can't change the ports (80 and 8080). Maybe there is the problem? Next I would like to control one of the two printers with klipper. How to install this? Is that even possible? I'm a complete newbie to Docker. Can anyone give me tips on how to get the cams and Klipper to work?
