Describe your issue:

Hello everyone !

I have an issue with my 3D printer, on most (not all) of my prints I get this error :

{"code": "", "msg":"MCU 'mcu' shutdown: Move queue overflow", "values": []}

I am not sure why it started doing that (and increasing in regularity) and I could really use some help

Thank you in advance !!!

Hello, greetings my dear…
a tip perhaps →

try increasing the power of x and y

if too much power burns and maybe magic smoke

[tmc2209 stepper_x]
run_current = 0.65 # put 0.8 or 1

0.65 is too low I think.

[tmc2209 stepper_y]
run_current = 0.6 # put 1

live long and prosper

Looks like some sort of overload condition.
System load seems pretty high but the type of error rather points to an overload in the MCU.

Generally, this is a Klipper that has (closed source) modifications by Creality, so no further in depth support can be offered.
Please contact Creality directly.

Thank you very much for the tip, do I have to set this up in the slicer ?
If so, where do I change this parameter, I use OrcaSlicer ?
And else, where in Klipper do I change this ? :slight_smile:

Kind regards.

Thank you, I’ll try to contact them !

Kind regards.

What you can typically check is the size of your models and the resolution. Does the error only happen with big gcode files or respectively high resolution files? If yes, then this would point to some overload condition.

Another thing surely is keeping the printer busy with webcams, light-shows, imperial march via the beeper etc.

It started with only big g-code file, but lately it seems to happen even on small prints (>30 minutes)
I have tried to unplug the Webcam but that didn’t change a thing
I also don’t do the imperial march with the bipper :')
