I suspect the CAN board is overheating--it looks toasty.

I have come to the same conclusion. Even the extrusions (X and Y-axis are extremely hot - would sustain a burn if you gripped it hard.

We're boiling - only a 6hour print that finished. I can fry an egg on the X-Extrusion

But this is I am sure the problem - SB 2040 overheating.

Other than taking out the Canbus, cannot see a long term solution. Am going to use the canbus on the new 2.4 build and see how hot that gets. I must be a sucker for punishment but it is the only way I'll know for sure.  Toolhead end won't be as hot as it sits lower than the Trident. Heat rises. Mmmhhh

Think the chip (2040) is only rated up to 85C (down to -20....or perhaps even -40 now). So if the ambient temperature is hitting 75C then I'm not surprised the Canbus is conking out (dunno about other components on the board). Time to invest in liquid cooling? Or perhaps some sort of heat-pump/thermo-couple and turn that Voron into a power-plant...
