MCU 'mcu' shutdown: ADC out of range

I got the following Error: MCU 'mcu' shutdown: ADC out of range This generally occurs when a heater temperature exceeds its configured min_temp or max_temp. Once the underlying issue is corrected, use the "FIRMWARE_RESTART" command to reset the firmware, reload the config, and restart the host software. Printer is shutdown How can I solve it? I don't use an extruder or heater temperature sensor for my application.

I'm curious, if you don't mind me asking, what is your application?

Hi, sure! We are actually two students and for a big project we are trying to build a liquid metal 3D printer to make stretchable electronics. So instead of the basic Filament we will try to use a syringe with the liquid metal. We are both quite inexperienced with 3D printers so more questions will possibly follow :). Thanks!

Oh cool! How come you went with RatOS?

We are both masterstudents at (Immo)-IMEC and this is part of or thesis so we did a liturature review to explore which printer is the best for or project. The software and the fact that RatRig is completely open source won us over.
