Cannot start Klipper

[jankorous]

Unfortunately I had to reinstall Klipper today. After updating everything and installing all the components I used before installing, I ran into problems with LED Effects:

Unhandled exception during ready callback
Traceback (most recent call last):
  File "/home/biqu/klipper/klippy/klippy.py", line 164, in _connect
    cb()
  File "/home/biqu/klipper/klippy/extras/led_effect.py", line 397, in _handle_ready
    for i in range(ledChain.led_helper.get_led_count()):
AttributeError: 'LEDHelper' object has no attribute 'get_led_count'
Transition to shutdown state: Internal error during ready callback: 'LEDHelper' object has no attribute 'get_led_count'

led_effect in v0.0.12-0-g03a46eab version, klipper v0.12.0-315-g8f361a15, mainsail v2.12.0.

i already reported this bug,you should # your neopixel setup for the moment so u can run klipper again =)

https://github.com/julianschill/klipper-led_effect/issues/223

the led_effect.py needs to be edited, it is best to disable led_effect in your config file until led_effect.py has been edited

FYI, if you are familiar with the command line and git, you could run

git reset --hard ef75346861fdf94d952a4e887fb843d215b00631

in the klipper folder to reset klipper to the state just before the breaking change and avoid updating it until this module gets patched. Restart the printer afterwards and you should be good to go.

Just be careful. As a rule of thumb, if you don't understand what I wrote, just # the neopixel config as @Zarrsito mentioned. It's easier to fix than a broken klipper installation.

I am having same issue but not sure how to fix this.

Either roll back the Klipper update or comment out all led_effect instances in your config.

I commented it out for the moment.

roll back your update until it is resolved

Has been fixed now.

I'm still experiencing failures:

@thetic Your error is not related to LED effects, but to "Virtual LEDs".

My mistake. Thank you
