Describe your issue:

I am having a hard time setting up klipper on my ender printer. It connects just fine to octoprint with other firmware, but when i switch, it dosen’t want to connect. Does anyone have a .bin that I can use. I have tried to made my own, but am not finding too much luck

Update I was able to create a bin, but I am still not able to connect it through OctoPrint

Did the firmware flash correctly?
Google Creality 4.2.2 firmware.

Your board is notoriously hard to flash. Use a smallish SD card (or partition a big one with a single 4GB partition) formatted with 4k sectors. AND rename your .bin file. To prevent accidental reflashing if the user doesn’t remove the card it will NOT flash a file with the same filename as the one used to load the current firmware.

@EddyMI3D Assuming Klipper flashed to the board are there any tricks to get Octoprint to connect?

Depends on the kind of installation: On a OctoPi/Klipper installation, the serial port is a different one as on a KIAUH/OctoPrint installation.

Also: foosel already works on a connection OctoPrint → Moonraker: Recommendation for Octoprint compatible printers - #5 by foosel - General - OctoPrint Community Forum

Hi @asdfdsa ,

Once you flash Klipper, you still need to configure Klippy (through OctoKlipper), then you can use OctoPrint.

Thank you. I belive I got the firmware swaped correctly. I am running Octoprint off an old laptop running Linux. I was able to connecet to the printer with marlin firmware, but after powering on with the klipper.bin, I haven’t been able to connect. I have also pasted a printer.cfg to octoprint throught the klipper plugin. I’m not too sure what to do next.

I assume you have installed Klipper on that laptop?

yeah, thats where I ended up creating my .bin. Do I also need to also run klipper while I am running OctoPrint?

Yes.

Klippy (on laptop or Pi) connects to Klipper on the printer’s board.
OctoPrint connects to Klippy and to your local network.

To run your printer, Klipper needs to be constantly running.
