General Discussion

Basic Information:

Printer Model: RatRig Style
MCU / Printerboard: Octopus Pro
Host / SBC
klippy(6).zip (3.5 MB)

I have installed on my printer the Klipper Toolchanger Code from Viesturz.
That worked really well.
Today I updated klipper to: v0.13.0-254-ga89694ac

Now I have error messaegs like:

  • ‘GenericPrinterRail’ object has no attribute ‘generate_steps’

  • Internal error on command:“MANUAL_RAIL”
    Once the underlying issue is corrected, use the
    “FIRMWARE_RESTART” command to reset the firmware, reload the
    config, and restart the host software.
    Printer is shutdown

  • 11:45:46 $ G28 X
    11:45:46 // Activating extruder extruder1
    11:45:48 // Klipper state: Shutdown
    11:45:48 !! Internal error on command:“MANUAL_RAIL”
    11:45:48 !! Internal error on command:“HOME_TC0”
    11:45:48 !! Internal error on command:“G28”

Hi @TimoTimo ,

There were some pretty big changes to the internal motion code recently.

If you run the below commands in SSH to revert Klipper, does the error persist?

cd ~/klipper
sudo systemctl stop klipper
git reset --hard 60879fd29
sudo systemctl start klipper

If the error is gone after those commands, I would open an issue on the klipper-toolchanger Github.

Hey thanks for your help.
I put the software back to v0.13.0-177-gef4c76fe.

Now the printer works fine again.
