General Discussion

Basic Information:

Printer Model: OpenBeam Kossel Pro
MCU / Printerboard: Azteeg X5 Mini (lpc1769)
Host / SBC: Raspberry Pi
klippy.log (1.0 MB)

Describe your issue:

…I’m hoping someone can help me get across the finish line.

I dug up an old Azteeg X5 Mini that I want to get running on a delta. I’ve created the makefile (lpc1769 chipset) with bootloader, etc

  • Created the klipper.bin
  • Copied to SD Card
  • Renamed firmware.bin
  • Inserted and powered up board
  • /dev/serial/by-id/ is showing the correct information: usb-Klipper_lpc1769_13D0FF08880449AE6D916E54C32000F5-if00
  • Added this to the [mcu] of printer.cfg
  • Restarted klipper, and still getting “Printer is not ready”

Where I’m stuck is that I’m seeing the device on /dev/serial/by-id/, but klippy.log is still saying:

mcu 'mcu': Unable to open serial port: [Errno 2] could not open port /dev/serial/bi-id/usb-Klipper_lpc1769_13D0FF08880449AE6D916E54C32000F5-if00: [Errno 2] No such file or directory: '/dev/serial/bi-id/usb-Klipper_lpc1769_13D0FF08880449AE6D916E54C32000F5-if00'

I’m not sure what’s missing - can anyone help me get this last bit sorted? Thank you in advance.

try doing an ls /dev/ and check for usb, tty or acm* devices and try the initial connection over serial.
also make sure its a lpc1769 and not a lpc1768! caught me out on my machine!

Thanks, I’ll try that
To confirm, you’re saying to update the [mcu] to something like:
serial: /dev/ttyACM0, or something similar?

…And yes, I’ve confirmed it is a 1769.

Yeah, I originally had the following

[mcu]
serial: /dev/ttyACM0

later I then changed it to by-id when I added more serial devices. See if it at leasts connects with that :woman_shrugging:
