Printer Model: Voron
MCU / Printerboard: MKS SKIPR w/ external Raspi 3b
klippy.log (2.6 MB)
Config: MKS SKIPR with external RasPi, flashed with the latest klipper (275) and with katapult (ex CanBoot), communicating with a Fysetc SB CAN TH, also running katapult and 275.
To start, everything was working fine, so no hardware issue. Then I updated my system(SW), and hell broke loose.
Long story short, I updated a lot and run through several problems, but now I can at least communicate with my printer.
But the problem that occurs now is that even if it does nothing, I get alot of
b'Got error -1 in can write: (105)No buffer space available'
MCU 'mcu' shutdown: Timer too close
events happen, causing the printer to shutdown, even if it does nothing. Sometimes it runs for a minute, sometimes it crashes directly. I cannot really guess why this is happening.
Can settings are:
allow-hotplug can0 iface can0 can static bitrate 500000 up ifconfig $IFACE txqueuelen 1024 pre-up ip link set can0 type can bitrate 500000 pre-up ip link set can0 txqueuelen 1024
as before. That was a well working environment once.
I have searches the internet and this forum for similar issues, but have found nothing that did help me.
So… any ideas??
