This specific config crashes the latest klipper version

[Nyegaard]

I did a little experiment that didn't work but still had this config section in my led_effects.cfg file: `#####################

whole_top_strip

#####################

[led_effect top_strip_stroboscope] leds: neopixel:top_strip autostart: false frame_rate: 60 layers: strobe 110 100 top (0.0, 0.0, 0.0, 1.0)

[gcode_macro stroboscope] gcode: STOP_LED_EFFECTS SET_LED_EFFECT EFFECT=top_strip_stroboscope`

when starting klipper after I updated tonight, I got this error message. This was only happening on the chain connected to my klipper expander, so I tried upgrading the mcu there and on the octopus for good measure to all be on the latest klipper version, but no luck until I figured out it was this led effect that caused it, giving the following error in klippy.log:

Unhandled exception during run Traceback (most recent call last): File "/home/pi/klipper/klippy/klippy.py", line 217, in run self.reactor.run() File "/home/pi/klipper/klippy/reactor.py", line 292, in run g_next.switch() File "/home/pi/klipper/klippy/reactor.py", line 340, in _dispatch_loop timeout = self._check_timers(eventtime, busy) File "/home/pi/klipper/klippy/reactor.py", line 158, in _check_timers t.waketime = waketime = t.callback(eventtime) File "/home/pi/klipper/klippy/extras/led_effect.py", line 177, in _getFrames frames = [(effect, effect.getFrame(eventtime)) for effect in self.effects] File "/home/pi/klipper/klippy/extras/led_effect.py", line 177, in <listcomp> frames = [(effect, effect.getFrame(eventtime)) for effect in self.effects] File "/home/pi/klipper/klippy/extras/led_effect.py", line 413, in getFrame layerFrame = layer.nextFrame(eventtime) File "/home/pi/klipper/klippy/extras/led_effect.py", line 485, in nextFrame return self.thisFrame[self.frameNumber] IndexError: list index out of range Transition to shutdown state: Unhandled exception during run klippy (10).log

Full klippy.log attached to the issue.

I have the same problem unfortunately. Any fix in sight?

For the strobe effect the effect rate (the first parameter) can't be greater than the frame rate. So set it to 1 or so and it should work: strobe 1.00 100.00 top (0.0, 0.0, 0.0, 1.0)

I will add a check to the code.

It works when removing the strobe effect, thanks.

I'm new to Klipper but have been dealing with a few issues when installing add-ons to it. Most of them are due to the changes made to moonraker and klipper lately. I noticed that in the install for this bit of software that it references the klipper_config folder. That folder no longer exists in the newer installs of klipper. Is this being addressed as well?

i am waiting to at least folder correction.

Fixed by v0.0.10
