Klipper not connecting after new installation

General Discussion

In this ecosystem you have different players:

  • Klipper Host software running on your RPi
    • Processes your config
    • Does all the management
    • Reads and processes your gcode to be printed
    • etc
  • Klipper Firmware on your printer, aka [mcu]
    • Typically connects to the Klipper Host via the serial paths in your printer.cfg
    • Receives the command from Klipper Host
    • Manages your printer’s hardware
  • Klipper Host MCU, aka [mcu rpi]
    • Typically connects to the Klipper Host via /tmp/klipper_host_mcu
    • Allows to use the RPi as kind of MCU to manage hardware, e.g. for ADXL IMUs etc
  • Moonraker
    • Typically connects to Klipper Host via /tmp/klippy_uds or ~/<datapath>/comms/moonraker.sock or the -a argument in the env
    • Other connection paths can be specified in the moonraker.cfg
    • Serves as an interface process to direct information and commands between, e.g. a webinterface (fluidd, mainsail etc) and the Klipper Host
  • Webinterfaces, e.g. fluidd, mainsail, klipper-screen etc
    • Connect to Moonraker via a http port
    • Allows the user to monitor and command the printing process

In your case the connection between Klipper Host and Moonraker was not working due to a mismatch in the connection paths.

I have a very similar situation here. Any one with the time to help

If it is very similar, you should be able to solve your issue with the information in this thread. Otherwise start a new one and provide the relevant information.

Hi Sineos, I did start a new thread (502 bad gate way) the one you have not responded to after threatening my privlages in this group.

Dangerous waters @Jamiekay, very dangerous. You do not want me to go into public with this now, since I have access to the previous content of this post.

So I propose that you now tread carefully, open a new post in “General Discussion” and properly provide the asked for information.

Amazing!!! I wish I could send you a donation for this… I was just about to give up on Klipper and all the work I put into learning it over this issue. Not only did your instructions fix my problem, but your explanation taught me a lot about the components involved for future troubleshooting.
