Me3D Me2 extruder drops violently at end of print

  • Hi,

    I just got a 2nd hand Me3D Me2 and using Matter Control, works great except at the end of the print, the head violently drops onto the bed. I'm worried about damage long term.

    Is this a problem I can fix in Matter Control, or something with the printer itself?

    I think you need to remove this line from you end gocde.

    M84 ; disable motors

    It looks like your printer does not hold the extruder up unless the motors have current.

    Hmm I'm not seeing that line, perhaps I need to add something instead?

    Current end gcode:

    G91; Set to Relative position
    G1 Z3 E-3; move z axis up
    G28 ; home axis
    G1 F250 E-16; Retract filament from barrel
    G92 E0; zero the extruded length
    G90; Set to Absolute position
    M104 S0 ; turn off temperature
    M140 S0 ; turn off heated bed
    M106 S0 ; Turn off fan
    M117 All Done!!!
