Hi Guys,
I have just finished to mount and connect my new Ratrig vcore 3.1 and installed Klipper following the guide on Ratrig website.
Once the configuration is finished I removed from ihe printer.cfg the # in the Hotend section next to the Revo and i removed the # also in the Toolboard section (i have the BTT EBB42 1.2 correctly flashed via RatOS configurator).

I always see the errore "Mcu Toolboard adc out of range" when i start Klipper.

This is the datasheet of the REVO Voron:
Max Printing Temperature: 300°C
Mass: ~25g
Temperature sensor type: thermistor, Semitec 104NT-4-R025H42G
Voltage options: 12V or 24V
Wattage: 40W
Filament diameter: 1.75mm

PS:
If I connect the Phaetus Rapido 2 to my toolboard and choose the Rapido into the Printer.cfg, i can read the temperature in the dashboard and the printer works fine.

Thank you in advance 🙂

You're saying that you're getting adc out of range error (which a quick google search would tell you is because of thermistor problems) without a thermistor attached, and it goes away when you attached a thermistor. So.. what's the issue?

i have ATTACHED the E3D Revo and i read the error.
But if i ATTACH the Phaetus Rapido 2 it works.

Ah, gotcha, are you sure the Revo thermistor isn't the problem?

ok, what value i must read ?

#

kOhm?

#

My T Amb is about 30°

I expect there's no continuity however

(pretty much the only way you're going to get that error)
