How know driver temperature?

Basic Information:

Printer Model: Vcore 31
MCU / Printerboard: Octopus pro + ebb42
klippy.log its bigger than 8 mb

Hi,

I think I had mentioned it before, but I think I have heating problems in the extruder driver, which is mounted on the EBB42.

I deduce this, because when I send a gcode to print, and I have the Top Lid of the printer open, it extrudes fine… but after a few minutes, 2 or 3 of lowering the top lid, it begins to lose steps, until it reaches a point which stops extruding.

At that moment I open the top lid, and I touch the extruder motor with my hand, and being hot, I don’t think it goes over 50 degrees, so I think it may be a driver temperature problem…

To check it, they told me that there is a console command

DUMP_TMC STEPPER=extruder [REGISTER=] that lists the Driver temperature, but I have tried to send it through the console, and a rather long list appears, of which I hardly understand any name.

What is the name of the value that informs me of the driver temperature?

The EBB SB2240 TMC2240 is the only one currently that can provide driver chip temp. The TMC2209 doesn’t provide chip temperature.
