Revision to Tuning the heater temperature control
|Each heating controller in RepRapFirmware 1.15 and later can work either in bang-bang mode of in PID mode. When operating in PID mode, it can get its PID parameters in either of two ways:|
|After power up or reset, the bed heater controller is in bang-bang mode and the extruder heaters use the model-derived PID parameters. If you use the M301 command to set the legacy PID parameters, the controller for that heater switches over to use them. If you run a successful auto tune or you set the model parameters manually using the M307, the controller switches back to using model-derived PID parameters.|
