Oozing filament at end of Print

  • I have tried adjusting the settings for length on move and speed and they helped with stringing on the print itself but I can't find how to adjust the end of a print to prevent filament from oozing when the print is over. There is a picture attached of the oozing along with the retraction settings 0_1529008586809_oozing.JPG 0_1529008442373_retraction settings current.JPG and below are my G-Code's for the start and end. Any help would be appreciated.

    Start Code
    G1 E1 F250
    G28 ; home all axes
    G29 ;autolevel
    G0 X0 Y0 F9000 ; Go to front
    G0 Z0.15 ; Drop to bed
    G92 E0 ; Zero the extruded length
    G1 X80 E25 F500 ; Extrude 25 mm of filament in a 8cm line
    G92 E0 ; Zero the extruded length
    G1 E-1 F500 ; Retract a little
    G1 X80 F4000 ; Quickly wipe away from the filament line
    G1 Z0.3 ; Raise and begin printing

    End Code
    M400 ;wait for buffer to clear
    M104 S0 ;turn off extruder
    M140 S0 ;turn off bed
    G91 ;relative positioning
    G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure
    G1 Z+0.5 E-5 X-20 Y-20 F{travel_speed} ;move Z up a bit and retract filament even more
    G28 X0 Y0 ;move X/Y to min endstops, so the head is out of the way
    M84 ;steppers off
    G90 ;absolute positioning

    @skrilla269 Check your acceleration on the extruder motor and increase the value and see if this makes a difference. If this is not enabled in the EEPROM, you may want to reflash the firmware.
