Unfortunately the issue came back. Qlen is still set right.
Will investigate some more. otherwise will gutt the EBB and wire the hotend directly to the board.
So I cant find the issue. which means I will step away from the EBB36. no big deal but have to revert back from CANBUS to USB mode.
Anyone know how to accomplish this without reflashing everything?
The SKR EZ V3 is in USB-CAN-Bridge config via Katapult which has its own bootloader.
Which means as well that I can only update via USB and the sdcard is not in use.
Can I just safely SHH into PI and then go into cd ~/katapult then make menuconfig and revert to USB?
Will the PI still be able to connect to the SKR EZ? there are zero to no writeups on how to revert.
I think the above should be possible and then ls /dev/serial/by-id/* to get the MCU serial ID for the PI klipper config to communicate with the MCU.
I’m not convinced that will solve your problems.
The temperature of your EBB36 is quite high.
I guess you have an EBB36 with a µC STM32G0B1CBT6?
The temperature grade is not sufficient for most 3D printers with a chamber.
Toolhead boards for 3D printers with a chamber should have a T3 grade.
thanks for checking. But the max temp is 80c? it hasnt got hotter than that.
I think I solved the issue.
Removed the entire CAN cable, redid all the crimps.
Installed the cable in such a way that it is not near or as close to power, motor wiring etc.
Ran a couple of long prints. Have not seen a bytes retransmit incremental increase. it stays at 0 and no CAN comms failures.
Lets hope that this is it.
I will probably at some point move away from CANBUS though.
