Extruder spins on print start after warm up

Hello,

For some reason my Prusa i3 Reprap printer with the latest Repeiter firmware will most of the time - start spinning the extruder for minutes before it moves the print head to the appropriate position after the bed and extruder hotend have reached the set tempurature.  If I kill the print job (resetting the Ardunio) and restart the print then it seems fine.  Not sure what to make of it.  Can anyone help out?

Thanks

    Might be related to these setting (also in eeprom present)

    /** \brief Temperature to retract filament when extruder is heating up. Overridden if EEPROM activated.
    */
    #define EXT0_WAIT_RETRACT_TEMP 150
    /** \brief Units (mm/inches) to retract filament when extruder is heating up. Overridden if EEPROM activated. Set
    to 0 to disable.
    */
    #define EXT0_WAIT_RETRACT_UNITS 0

    Hello,  My units setting was #define EXT0_WAIT_RETRACT_UNITS 500.  I have set it to zero and will see what happens.

    Thanks

    Remember it might also be in eeprom overriding your setting!
