Communication timeout during homing X/Y

[WatWall]

I get this error "Communication timeout during homing X" when I start printing.
Sometimes it happens on Y axis too. I retry printing 4-5 times and it works
Is there any fix for this?

Are you using the version with klipperscreen?

[WatWall]

Yes, Installed the latest with klipperscreen

[KaruroChori]

That error is due to latency in the linux side of klipper while trying to keep up with the firmware.
Klipperscreen might be a bit too much for the low spec board running it, and this jitter in latency is likely to cause the issue you are seeing from time to time.

If you can work over a network and you want a more stable environment I would suggest to stick with the headless version and control it remotely.

@consp made some progress recently in porting over a more lightweight UI; hopefully that should solve this problem in some future release.

Thanks. I installed the lite version. I just got the error once when I first opened the printer and homed manually. Then I did 4 test prints in a row and they all started without any error. It looks better now.
