Hey all,
Wanted to leave a quick note here thanking you for this thread. It Helped me with my can bus error.
The klippy error i was getting in my logs was:
b’Got error -1 in can write: (105)No buffer space available’
So while not the same as yours, your thread was helpful.
Changed the txqueuelen from 256 to 1024 and have completed one long print, 25 hours and two shorter prints 5 hours each and its running with no issues. Such a simple fix this time.
I am using a voron 2.4 with octopus pro board with the can bus ebb36 to the PA11/PA12 on the octopus board.
And with lots of help from the can bus to octopus pdf doc listed in the forum below.
Here is my latest output of the can0 with tons a packets passed and no buffer issues.
can0: flags=193<UP,RUNNING,NOARP> mtu 16
