Resetting the MP Select Mini Firmware Settings/EEPROM
See Sending G-code for more information on how to send the commands below.
Example for using
M502 to revert the MP Select Mini firmware to default settings
M502 ; Restores default settings M500 ; Saves the settings to EEPROM Reboot the printer
Rebooting the printer may not be necessary but it is recommended.
Example for using
M502 to temporarily revert the MP Select Mini firmware to default settings
M502 ; Restores default settings M501 ; Restores the setting currently stored in EEPROM. This is basically the same as turning the printer off and on.
Do not reboot (power cycle) the printer until you are ready to go back to previous settings.
Turn the printer off for about 1 or 2 seconds to return to previously stored settings
M502 resets all settings/parameters to the default values of the currently installed Motion Controller firmware. These settings are sometimes altered by the user or slicing software although I suspect the latter is less likely to have occurred.
Most often the two settings altered by the users are the PID values and the Steps per mm for the extruder stepper motor.
