Describe your issue: Cannot access ‘/dev/serial/by-id/’: No such file or directory

I have followed all the posts and tried what I think is everything.

I have tried different USB cables, I’ve tried different ports and the rest.

Here is my dmesg.txt file attached.

Please help.

Thanks.

What about uploading the klippy.log as well?
Did you flash the correct firmware to your printer so it can be found?

Hi. Thanks for your reply.

klippy.log uploaded to the OP. It’s here as well:
klippy.log (119.7 KB)
The file was found in this directory on the SBC (Radxa Zero): ~/printer_data/logs/klippy.log

I flashed the firmware created. The config file for the Aquila printer
printer-voxelab-aquila-2021.cfg (1.6 KB)
says to use STM32 selected, and I also selected to “Disable SWD at startup (for GigaDevice stm32f103 clones)” option for my G32 chip - though it doesn’t say that in the config file.

The firmware seems to have done its thing and the printer screen glitches out, and so then I waited for about ~1 minute, then turned the printer off and removed the SD Card.

I hope this all leads to something to help. Thanks for your time and inputs.

A bit of an update.

It was the micro-USB cable that wasn’t a data cable. So I can now connect to the Fluidd interface.

I’m now facing another issue where the MCU is unable to connect!

mcu ‘mcu’: Unable to connect
Once the underlying issue is corrected, use the
“FIRMWARE_RESTART” command to reset the firmware, reload the
config, and restart the host software.
Error configuring printer

I’ve Googled for 2 days now and tried the following:

  • reflashed the MCU
  • changed the config to vanilla Aquila cfg file
  • used ls /dev/serial/by-id/* to update the config file to:
[mcu]
serial: /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0
restart_method: command
  • used ls /dev/serial/by-path/* to update the config file to:
[mcu]
serial: /dev/serial/by-path/platform-xhci-hcd.0.auto-usb-0:1.1:1.0-port0
restart_method: command
  • taped over the power connector on the USB connector to the printer

latest Klippy.log:
klippy.log (807.8 KB)

Any other ideas?

Thanks.

See Issues flashing the printer board for potential reasons and solutions.

Thanks @Sineos
what I tried next was using the original 8Gb uSD card that came with the printer and Flashing the MCU with that. It worked.

The 128Mb uSD card did not work. The 8Gb uSD card worked to flash the MCU.

I have left the config as:

[mcu]
serial: /dev/serial/by-path/platform-xhci-hcd.0.auto-usb-0:1.1:1.0-port0
restart_method: command

Thanks for your support.
