Describe your issue:

Klippy is crashing without any good reason.
Ive changed the BTT PI, ive updated klipper.

It does seem to be connected to the file its printing.

And it also looks like it has something to do with the 2nd layer of the print.

I can not find some sort of unprocessed Gcode or something like this.

Ive had these issues before, but they seemed to have resolved itself.
But back then they were connected to using superslicer.

Prusaslicer did not have these issues, and now I changed to orcaslicer and they are back again.

So im a bit puzzled why this is happening.

Cuz there is an issue on GitHub saying klipper can not process the G1 command without an axis.

But the slicer keeps putting multiple of these lines in.

Heater extruder not heating at expected rate
Transition to shutdown state: Heater extruder not heating at expected rate
See the 'verify_heater' section in docs/Config_Reference.md
for the parameters that control this check.

Even if there is some communication issue with CAN0 device,
There is a heater issue, it is not normal to have a +0.3-degrees increase per 3 seconds with 100% PWM on the hotend.
So, there is either a heater issue or a thermistor.

not sure if that is from a previous error I fixed by properly;y seating the can cable

cuz that error is not visible in the part of the logfile that is connected to my errors

what’s the timestamp of those can0 errors ?
