Klipper config settings for minimizing MCU shutdowns?

[dragos240]

I've been using this firmware for a while now, maybe a year or so. And I do occasionally get MCU shutdowns, but lately I've also been getting the error Move queue overflow when I try to print things. I don't know why it's only happening now, but it does seem if I set the speed factor to a much slower speed like 33%, the problem does not occur. I also use Orca Slicer for slicing, but I have settings like arc fitting turned off.

I know in general MCU shutdowns are from the system overloading, so I disabled my webcam, but it doesn't seem to help.

So essentially I'm looking for things I can change in my config files to prevent this from happening.

In printer.base.cfg there's a line in [printer] called max_accel, which seems to be set by default to 20_000. Setting it to 10_000 made the queue overflow error completely disappear for me. It might be possible to go higher, but it's also prevented MCU shutdowns in general for me for some reason. Before I edited that value, I would get an MCU shutdown every other time I started a print. Now it's pretty uncommon. I'm not sure why that would help this, but it does seem to help.

So I guess it was just dumb luck, because the MCU showdowns have started again. So to anyone looking at this message, it doesn't actually prevent them, I was just lucky before.
