Basic Information: Printer Model: Voron 2.4 350 MCU / Printerboard: Octopus 1.1, SB2209 with U2C, PI4 klippy.log Describe your issue: Ive got Voron 2.4 with Octopus and SB2209 CAN board all connected to PI4, everything seems fine but ive got error in the middle of print as shown in photo attac…

I just restarted and will try to print it one more time.

This is exactly what I reported here Intermittent crashes with no obvious reason - #14 by patrik-zitko but no one, even Kevin helped. It seems to me like some bug related to CAN, as since that I did not had that problem. @koconnor pls check this, I am not the only one who is suffering this issue.

May I ask you where you found an evidence of unstable CAN? It is printing and suddenly the klipper service restart happen.

Both @Kromka_z_maslem and @patrik-zitko logs contains a lot of Got error -1 in can write: (105)No buffer space available So far you both are first ones, where I see this error. So I would guess it is not a common problem, given the fact that CAN usage in Klipper is quite widespread nowadays. Unfo…

I went through the docs before I made this thread, I would try to update the buffer size with something bigger, but honestly I really don’t know how it could help… I would really appreciate if I could be able to see at least something in the logs, all we can see is service restart with no exception…
