Allow running the model checking during autotuning, with the only exception being the parameter estimation stage where we alter the same value which is used by the checker (done to conserve memory/code). With previous changes the model checker will disable/enable itself when passing through an unavailable R vector entry, allowing to start the calibration by checking only the stages where the part fan is disabled. The C/R0 values should be stable enough to provide a fail-safe mechanism for printers of the same variant right from the factory.
