Press each MENU selection in order to begin 1) 4 Point Level Calibration, 2) Probe Z-Offset Calibration, 3) Auto Mesh Level Calibration and 4) Test. Each selection brings up a new menu to perform that task. Subsequently you only need to perform the Menu tasks that have not been Saved or that need to be updated.

When done with these MENUs move down to the next group of Special Menu selections.

Next you have the option to 1) Restore memory to the Factory Default EEPROM values, 2) Restore memory to the Last saved EEPROM values or 3) Save the current memory values to EEPROM.

Note: None of the newly calibrated values are save to EEPROM until Save to EEPROM is selected. If not saved to EEPROM the values will be lost if the printer is turned off.

From here move down to the next group of EEPROM related selections. After making your preferred EEPROM selections you may Exit the Special Menu or move down to the next group of additional Utility Special Menu selections.

SPEC_3

The PID controller (proportional-integral-derivative controller) reliably controls the heating of bed and nozzle. "Tuning" overwrites the values set in firmware and the heating is recalibrated. This is important when printing significantly higher temperatures and this may result in fluctuations. The standard PID tuning takes several minutes. A beep confirms successful tuning. However, it is important to know that under certain circumstances (very high or very low ambient temperature) the PID tuning even worsens the heating behavior. Here it is then necessary to reload the default / standard values.
