Revision to Tuning the heater temperature control

David Crocker

To see which set of parameters is being used, run M307 H# where H is the heater number, and that will tell you either that the model is in use (so model-based PID parameters are being used for that heater), or not in use (so legacy PID parameters are being used).
 
Each heating controller performs temperature monitoring to try to detect fault conditions such as a heater of thermistor falling out of an extruder heating block. The temperature monitor relies on the model parameters to decide what is reasonable behaviour. Therefore, even if you decide to use legacy PID parametersparameters or bang-bang control, you should still define an approximate model of the heater to provide good heater monitoring without false alarms.
