How to reset the error "Temperature reading fault on heater 1: sensor open circuit"
When I change the tool, I have to unplug the temperature sensor (it's attached to the tool). I don't want to restart the printer every time I change the tool.
After I change the tool, it shows the temperature (room temp), so the temperature sensor is OK, but I can't heat up the extruder because of the "unplug", and "plug back new one" sensor error.
Is there a way to reset the error?

It does not work for me!

I don't see why M562 won't work, although you may need a second or so delay between reconnecting the thermistor and sending M562, to allow the temperature reading to stabilise. Alternatively, if you turn the heater off by setting its temperature to 273 before you unplug the thermistor, then you may avoid the fault.

Can't get it to work.
I get the error when I remove the tool, and when I attach a new tool, I clear the error with M562 P0, it shows the temperature, but it's not doing anything when I was to raise the temperature with "G10 P0 S120" for example.
When I remove the tool, thermistor, and heater (and BL-Touch, and fans) gets unplugged, and then a new one is plugged in, I have a few of them
Until now, I always reset the printer, but in the future I want to do automatic tool changer, so I want to figure out this problem

Just discovered something new.
When I get the error, I send command "M562 P1", and it does not show "fault" anymore, then I use the web interface to change temperature, it sends "G10 P0 S120", and that does not work!
BUT !! If I send command "M104 S120", then it DOES WORK, after the M104, sending G10 P0 S120 (or any other temp) works after that.
So this looks to me like this is a bug in the software

It's not a bug because resetting a heater fault turns the heater off. An alternative way to turn it back on is to reselect the tool using a T command, e.g. T0 if you have only one tool.
