could try this while you wait, but do take note its a poor solution, I only used it for a chamber sensor with no heater.

I'm using the original cetus thermistor. It works well after finding the correct values for it.

I do not think a negative B value is common.

Looks like you are using a PT100 but you have connected it directly to the thermistor input. This will give you a very poor resolution and you should use the PT100 daughter board instead. However, if you want to use a direct connection then I suggest this:

M305 P1 X501 R47000

This says you are using a PT1000 sensor, but inflates the series resistor value by a factor of 10 to compensate for the fact that you are actually using a PT100.
