Thank you. I get this message for the git checkout… pathspec ‘work-trsync-20240102’ did not match any file(s) known to git
nevermind i got it switched
FYI, I recently committed PR #6453 to the main Klipper repository. That PR has some of the timing tweaks discussed here.

Hi, I will test them as soon as I find some time, sorry I am very busy right now.
Hi. Found this tread. Installed klipper from work-trsync-20240102, hope that helps to fix my trouble.
PR #6453 already merged, newest klipper installed, firmware updated, but i still have a random error :
“MCU ‘EBBCan’ shutdown: Missed scheduling of next digital out event”
i believe it could be related with stepper driver
here is some log

Just FYI: I won’t have time to test your work within the next 4 weeks. As soon as I am back, you will get some feedback. I have not forgotten the issue 
Just for information. Reverted back to main repo. I believe lowering can0 speed allow me to solve problem. Now can works on 250000 bitrate.
allow-hotplug can0
iface can0 can static
bitrate 250000
up ifconfig $IFACE txqueuelen 1024
EBB works on 250000 too.
Keep watching logs and debugging.
