I have tried increasing all buffers and it did not make a difference. Maybe more adjustments are needed?

ummm...you're using a remix & not official marlin ... and you also haven't told what control board you're using.

rerickson1 commented 11 months ago

Control board is listed up in the description. What do you mean by remix? I have taken vanilla marlin and applied the config settings for my board:

Without any customizations to marlin, this issue happens.

I have noticed the LCD only freezes when printing is in progress and there is motion in X/Y directions. During a tool change when there is no X/Y motion, the LCD unfreezes. Video: https://youtu.be/nyE4K4mlIH8 What can I try to troubleshoot this issue?

This is a duplicate of #24813

I looked into this recently and found a couple of possible sources that can cause this, but it is still freezing... Hopefully this will fix it 😉 : #26523

@thisiskeithb I would really like to help get to the bottom of this. This issue is present with this PR: https://github.com/MarlinFirmware/Marlin/pull/26635

There must be some loop starving the LCD update task. How can I enable some advanced debug? I tried increasing buffers and it didn't solve the issue, but maybe I did it wrong.

tommylux commented 1 week ago

I'm experiencing slow performance with the LCD when printing through OctoPrint. The LCD seems to lag, moving only one notch when I turn the dial, and often appears frozen. Pressing the dial selects a different menu because the selection hasn't updated. If I wait too long, the menu often closes out. I'm wondering if the buffer is getting overloaded and if there's a way to limit the number of commands OctoPrint sends. Any suggestions would be greatly appreciated. Thanks!

Look forward to any suggestion.

Thanks
