My Bambu X1C will do both of these and tell you when it’s time to lube the Z axis screws for example, but I think all printers will shut down if the thermistor (what measures the heat) is reading incorrectly due to it being bad or a problem with the extruder heater since not doing so could be catastrophic rather than just giving you a shitty quality print.

I’m not familiar with how the X1C does it, but the printers I’ve used can only tell if the temperature or resistance are outside of normal operating range—not if they differ from the exact values predicted at each point in the print.

The Bambu printers do some cool stuff with measuring resonance to measure things like lubrication and belt tension. This is theoretically possible on any machine that can do Klipper’s inout shaping, but requires a LOT of data to be useful (from what I understand), which is orobably why we don’t see many printers on the market that can do that.
For thermals, Marlin (one of the popular printer firmwares) actually evaluates the control response of the heater based on the, rather than just looking at a specific temperature range. If the behavior is sufficiently different than what the system is tuned for, it will throw a temp error and shut down before thermal runaway occurs. I would expect other modern firmwares (e.g. Klipper) do this as well, but I don’t have as much experience tinkering with them and don’t want to make definitive statements.

Can confirm, klipper does this too. Sincerely, someone who had a few thermistor related wire breaks.
