Biqu Pi not detecting Controlboard USB; Sees webcam

General Discussion

Basic Information:

Printer Model: Custom
MCU / Printerboard: Fysec Spider V2.3
klippy.log

klippy.log (23.3 KB)

So I will start to say I tested this with a genuine Pi4B without issues detecting the Spider USB, but still couldn’t get the MCU id. Also detected the webcam.

Now I am trying my Biqu Pi 1.2. Both this and the original Pi4 is using the latest klipper install, and latest generated firmware.bin file uploaded to the Spider via STM32 program. All went well.

But, with a lsusb command the only USB I see used is the webcam. I am at a loss of what to check. I originally thought the issue was setting the console=serial in the settings file of the biqu debian install, but that did not work.

klippy.log is telling you pretty clearly where your issue is:

[mcu]
serial = /dev/ttyACM0 restart_method: command

mcu 'mcu': Unable to open serial port: [Errno 2] could not open port /dev/ttyACM0 restart_method: command: [Errno 2] No such file or directory: '/dev/ttyACM0 restart_method: command'

my mistake, I added that while browsing for solutions, this issue occurs before I made this change.

Again the original problem is there is no usb detection of the Spider control board when I type lsusb into putty. only the webcam shows. But I verified the Spider is able to be detected by connecting a pi4 with klipper.

Regardless if it is looking in the right directory or not, I should be able to see the USB right? This I believe is my current issue, but PLEASE correct me if I am wrong.
