Arduino native port wont connect to octoprint

The programming port on my arduino due mysteriously broke(bloody cat) and I need to use the naqtive port. I erased the due and reflashed via the native port. I can control the printer from my lcd fine but octoprint will not connect to the port. I tried different ports in octoprint but to no avail. If I ssh into the pi it shows

Bus 001 Device 003: ID 2341:003e Arduino SA
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
so its there but can anyone advise?


I'm not sure if I understand your setup
We need more information
For starters what does the due do?

Logs would be quite handy too...

Print controller is radds 1.6 on arduino due. Firmware is MK4Due. Log is showing many WARNING - 409 GET /api/printer (::ffff:192.168.x.x) 86.10ms

Yes, but for further more investigation, it would be really good if you would share the logs: octoprint.log and serial.log


octoprint.log (120 KB)

serial (1).log (2.13 KB)

Referring to the serial.log, the serial connection from OctoPi to the Arduino board is established.
But OctoPrint can not establish a connection to the Firmware.
You said, you uploaded a new firmware to the Arduino. Maybe with the configuration of the firmware (Marlin?) is something wrong.
