Basic Information:

Printer Model: Sovol Sv 07 plus
MCU / Printerboard: STM32F103
Host / SBC
klippy.log Doesnt exist right now?

Describe your issue:

I bought the bigtreetech Eddy and wanted to update my Klipper software to be able to use the sensor to its full extent. However, the installation according to the guide (https://github.com/3DPrintDemon/How-to-Update-Sovol-Klipper-Screen-To-Latest-Klipper-SV06-and-SV07/blob/main/README.md) with the Klipper software from Bigtreetech did not work and I have been stuck ever since. I have already tried to reset the 3D printer to factory settings with the original firmware from Sovol (.deb) without success. I insert the USB stick into the printer, it recognizes it and updates

the firmware, after it has done this the Klipper interface appears normally and everything works (at least for the first few smaller prints before the message appears that the CPU is overloaded, for whatever reason). As soon as I try to start the 3D printer without the USB stick, it can’t connect to Moonraker and Klipper (see picture). The fact that the 3D printer works when the USB stick with firmware is inserted in the 3D printer suggests that everything is actually OK with the STM32F103, right? Why does it only start with the firmware on the USB stick but not with the files created by the firmware?

@EddyMI3D bitte hilf mir xd

It should. Any chance to access Moonraker via Mainsail/Fluidd?

After your comment i went looking for it again and in the mainsail interface when i opened the Klipper log i only found:

{”error": {“code”: 404, “message”: “Not Found”, “traceback”: “Traceback (most recent call last):\n\n File \”/home/mks/moonraker-env/lib/python3.7/site-packages/tornado/web.py\“, line 1713, in _execute\n result = await result\n\n File \”/home/mks/moonraker/moonraker/components/application. py\“, line 796, in get\n self.root, absolute_path)\n\n File \”/home/mks/moonraker-env/lib/python3.7/site-packages/tornado/web.py\“, line 2813, in validate_absolute_path\n raise HTTPError(404)\n\ntornado.web.HTTPError: HTTP 404: Not Found\n”}}”.

This led me to the conclusion that Klipper was not installed correctly. Cause of the Problem: Klipper installation with Kiauh does not work on the MKSPi. Solution: Installation via an image using these instruction: GitHub - TomasOlsson/BrickedSv07-Sv07Plus: This is just for users that have bricked their Sovol Sv07 printer.

I will probably have to wait until the eddy sensor is fully usable without installing another version of klipper

Thanks for your time you put into this forum

The latest Klipper git should have all necessary changes to work with the BTT Eddy sensor.
