    I just purchased a Robo 3D R1 Plus. I've updated the firmware to ROBO3DR1PLUSV2. I'm trying to calibrate the extrusion by measuring the actual extrusion length. When extruding 100mm, it actually only extruded 85mm. So i've updated the firmware with following:

    //#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,800,723.38} // default steps per unit for RoBo 3D R1
    #define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,800,846.76} // X,Y,Z,E

    After flashing the updated firmware with above changes, I tested the extrusion again with 100mm but still only got 85mm.

    Why isn't the new steps per unit having any effect?

    Command I use to extrude 100mm is:
    G92E0
    G1E100F90

    Maybe you have overridden the firmware defaults with Matter control EEPROM options?
    I never use or suggest using the flash eprom ... I'd rather know a firmware update will work immediately :)

    GCode:
    M500 Store current settings in EEPROM for the next startup or M501.
    M501 Read all parameters from EEPROM. (Or, undo changes.)
    M502 Reset current settings to defaults, as set in Configurations.h. (Follow with M500 to reset the EEPROM too.)

    So after firmware is fixed you need the M502 and an M500 at some point for them to work.

    Sweet. Just remember that if you need to make other changes in the future.
    The flash EEPROM overrides the firmware.
