Setup<\/h2>\n\n\n\n

I have multiple printers connected to my PC running Klipper: Creality Ender 5+, CR6-SE and Ender 3 S1 Pro. <\/p>\n\n\n\n

I used kiauh<\/strong>, GitHub - dw-0\/kiauh: Klipper Installation And Update Helper<\/a><\/code>, to install 3 instances of Klipper, Moonraker, Mainsail and Fluidd.<\/p>\n\n\n\n

I tried both Debian 12 and Ubuntu 22.04.3 LTS. kiauh <\/code>successfully installed all of the packages on both OSes but I could not configure the USB ports correctly on Ubuntu. I didn’t capture the errors before I wiped the system and installed Debian. Will need to try again on a different system.<\/p>\n\n\n\n

I now have a directory for each printer:<\/p>\n\n\n\n

drwxr-xr-x 10 klipper klipper 4096 Sep 3 23:53 CR6SE_data
drwxr-xr-x 10 klipper klipper 4096 Sep 3 23:53 E3S1Pro_data
drwxr-xr-x 10 klipper klipper 4096 Sep 3 23:53 E5Plus_data<\/code><\/pre>\n\n\n\n
along with directories for the various components:<\/p>\n\n\n\n

USB ports<\/h2>\n\n\n\n
Each time the PC boots, it assigns a different USB port to each printer (only two are connected right now)<\/p>\n\n\n\n
klipper@klipper1:~$ sudo dmesg | grep ttyUSB
[ 5.580820] usb 1-2.4: FTDI USB Serial Device converter now attached to ttyUSB0
[ 5.581119] usb 1-2.2: ch341-uart converter now attached to ttyUSB1
[ 1213.719327] ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0
[ 1215.624744] usb 1-2.4: FTDI USB Serial Device converter now attached to ttyUSB2
[ 2418.419348] ftdi_sio ttyUSB2: FTDI USB Serial Device converter now disconnected from ttyUSB2
[ 2420.328872] usb 1-2.4: FTDI USB Serial Device converter now attached to ttyUSB0<\/code><\/pre>\n\n\n\n
And the \/dev\/ttyUSB<\/code> devices:<\/p>\n\n\n\n
klipper@klipper1:~$ ls -ld \/dev\/ttyUSB*
crw-rw----+ 1 root dialout 188, 0 Sep 6 23:19 \/dev\/ttyUSB0
crw-rw----+ 1 root dialout 188, 1 Sep 6 23:25 \/dev\/ttyUSB1<\/code><\/pre>\n\n\n\n
The problem was, I thought I was being smart by specifying the USB port in printer.cfg<\/code>, but which learned is most probably wrong after a reboot. Ex. for the E5Plus:<\/p>\n\n\n\n
197 [mcu]\n198 serial: \/dev\/ttyUSB2<\/code><\/pre>\n\n\n\n
And for the CR6-SE:<\/p>\n\n\n\n
195 [mcu]\n196 serial: \/dev\/ttyUSB1\n197 restart_method: command<\/code><\/pre>\n\n\n\n
The correct thing to do is specify the \/dev\/serial\/by-id<\/code><\/p>\n\n\n\n
klipper@klipper1:\/dev\/serial\/by-id$ ls -l \/dev\/serial\/by-id
total 0
lrwxrwxrwx 1 root root 13 Sep 6 17:41 usb-1a86_USB_Serial-if00-port0 -> ..\/..\/ttyUSB1
lrwxrwxrwx 1 root root 13 Sep 6 23:19 usb-FTDI_FT232R_USB_UART_AB0KE6G5-if00-port0 -> ..\/..\/ttyUSB0<\/code><\/pre>\n\n\n\n
So for the E5Plus<\/p>\n\n\n\n
[mcu]
serial: \/dev\/serial\/by-id\/usb-FTDI_FT232R_USB_UART_AB0KE6G5-if00-port0<\/code><\/pre>\n\n\n\n
And the CR6-SE<\/p>\n\n\n\n
[mcu]
serial: \/dev\/serial\/by-id\/usb-1a86_USB_Serial-if00-port0
restart_method: command<\/code><\/pre>\n\n\n\n
I also discovered the udevadm <\/strong><\/code>command which provides a lot of information about a connected USB device<\/p>\n\n\n\n

Powering off the printers<\/h2>\n\n\n\n
If I power off the AC to the printers, the fans and motors turn off but their mainboards are still powered via the USB from the PC. The E5Plus’ screen remains lit but the CR6SE’s screen flickers annoyingly. So, I unplug the USB cables from the PC. The PC detects the disconnect and removes the USB devices:<\/p>\n\n\n\n
klipper@klipper1:~$ sudo dmesg | grep USB<\/strong>\n...\n[ 7192.491354] ch341-uart ttyUSB1: usb_serial_generic_read_bulk_callback - urb stopped: -32\n[ 7192.491871] ch341-uart ttyUSB1: usb_serial_generic_read_bulk_callback - urb stopped: -32\n[ 7192.545458] usb 1-2.2: USB disconnect, device number 5\n[ 7192.548319] ch341-uart ttyUSB1: ch341-uart converter now disconnected from ttyUSB1\n[ 7193.313261] usb 1-2.4: USB disconnect, device number 6\n[ 7193.314428] ftdi_sio ttyUSB2: FTDI USB Serial Device converter now disconnected from ttyUSB2<\/code><\/pre>\n\n\n\n
Changing the printer name in fluidd<\/h2>\n\n\n\n
By default, every printer is called fluidd<\/em>, which is confusing because you have to remember which moonraker port each printer is connected to (7125, 7126, etc)<\/p>\n\n\n\n
In the web GUI, go to Settings (the gear icon):<\/p>\n\n\n\n
\"\"<\/a><\/figure>\n\n\n\n
Then change the Printer Name:<\/p>\n\n\n\n
\"\"<\/a><\/figure>\n\n\n\n
The change happens as soon as you hit return – there is no Save button.<\/p>\n\n\n\n
The printer name is stored in ~\/printer<\/em>_data\/databases\/data.mdb<\/code>. I can see it with strings<\/code>:<\/p>\n\n\n\n
klipper@klipper1:~\/E5Plus_data\/database$ strings data.mdb\nfluidd\nauthorized_users\nupdate_manager\nhistory\nannouncements\nuiSettings{\"general\": {\"instanceName\": \"E5Plus<\/mark>\"}}\nlayout\ncameras{}<\/code><\/pre>\n\n\n\n
But I cannot find it in the dump created by mdb_dump<\/code>. First install lmdb-utils<\/code>:<\/p>\n\n\n\n
