Usage

• M500
• M500 P31
• M500 P10
• M500 P10:31

Save current parameters to the sys/config-override.g on the SD card. (similar to other firmware's storing to EEPROM). Implemented in RepRapFirmware 1.17 and later. The parameters stored are:

• M307 auto tune results
• PID parameters, if you used M301 to override the auto tune PID settings
• Delta printer M665 and M666 settings
• Any M208 axis limits that were determined using a G1 S3 move
• If the P31 parameter is used, the G31 trigger height, trigger value and X and Y offsets for each possible Z probe type (in older firmware versions the G31 parameters are stored even if the P31 parameter is not present)
• If the P10 parameter is present, the G10 tool offsets

Ensure that M501 is at the end of config.g in order for the values in config-override.g to be loaded on startup.
