Hi
I’m having an issue on the mellow sb2040 can bus controller. There are two blue LEDs on the controller; one is a power light the other indicates the can-bus connection (I assume).
Normally, if I switch on my printer (V2.4) both LED are on immediately.
Sometimes only the power LED is on. When that happens I haven’t found any other solution then power cycling the printer until both led are on.
I don't know if I need to worry about that, are there any thoughts on this?
If the printer starts normal (Both LEDs are on) there is no other issue to the can-bus. I did several multi-hour prints without any connection problems.
This is satus of a current print
pi@mainsailos:~ $ ip -s link show can0
4: can0: <NOARP,UP,LOWER_UP,ECHO> mtu 16 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1024
link/can
RX: bytes packets errors dropped missed mcast
655008 106377 0 0 0 0
TX: bytes packets errors dropped carrier collsns
2168331 286091 0 0 0 0
This is my setup:
Voron 2.4r2 Formbot
Stelthburner+CW2+Tap
Mellow SB2040
RPI4 with waveshare can-hat
Octopus with klipper FW (no canboot)
I’m using the cables that come with the mellow kit in the cable chain
Best regards
Markus
